The question is trivial. We first recommend determining the installation location of the homemade fan. The technique dominates two types of engines: collector (historically first), asynchronous (invented by Nikola Tesla). The first is very noisy, switching sections causes a spark, brushes rub, causing noise. Asynchronous engine with a short-circuited rotor trotter, noise generates less. Put-protection relay will find in the refrigerator. By adding a pair of frases like fun phrases, we will refund the seriousness of the site. How to make a fan with your own hands, do not scare relatives. Let's try to answer.

Aspects of the design of the self-made fan

The fan device is so simple, the meaning disappears to tell, paint inside. What to take into account when designing? Remember the growl of the cyclone vacuum cleaner, the volume is above 70 dB. Inside collector Engine. More often eliminated revolutions. Decide, at the installation site of the homemade fan, let's say a similar sound pressure level? By choosing the second, concentrate on asynchronous motors, simple models do not require a starting winding. Power is small, the secondary EDF is guided by the Stator field.

The drum of an asynchronous motor with a short-circuited rotor is cut through copper veins by forming, corner to the axis. The direction of the slope determines the direction of rotation of the engine rotor. Copper veins are not isolated from the drum material, the conductivity of the Olympic metal is superior to the surrounding material (silumin), the difference of potentials between neighboring residents is small. The current flows on copper. Meaning the stator, the rotor does not have contact, Iskre is not yet engaged (wire is covered with lacquer insulation).

The noise of the asynchronous motor is determined by two factors:

1. The alternator and the rotor is.
2. Bearing quality.

Correcting the setting, maintenance of an asynchronous engine, can be achieved almost complete silent. We recommend thinking whether the level of sound pressure is important. It concerns the channel fan- is allowed to use the collector engine, the requirements will set the location of the section.

The channel fan put inside the duct section, mount, breaking the path. For maintenance, the section is withdrawn.

The noise loses the primary role. Sound wave, passing the air duct, fades. Especially fast part of the spectrum having inconsistent dimensions relative to the width / length of the cross section of the path. For details, read textbooks on acoustic lines. The collector engine can be used in the basement, garage, deprived of people. The neighbors of the cooperative will hear, rather bend attention to pay attention.

What is a good collector engine that we fight for the right to use. Three lack of asynchronous:

At the initial moment, an asynchronous engine does not develop a large torque, a number of special constructive measures are being taken. For fan, it does not matter. Most household models are equipped with asynchronous engines. At production, the number of phases increase to three.

Search Engine for fan

In one video, YouTube was offered to use the engine direct current 3 volts from the shopping store. Copies USB cord, running, rotating a laser disk blade. Useful invention? If you are tired of an extra port, the heat will help to survive. It is easier to take a processor cooler, squeeze from the system unit. 12 volts are yellow wire (red on 5). Black couple - Earth. From the old computer will collect. Citizens of the Russian Federation just laziness to invent, throw out curious equipment for a landfill.

Asynchronous fan engines operate without a starting capacitor ... The feature of the fan engines is: go straight with winding. A pair of tips to help get the engine:

Make a fan impeller

The question is from what to make a fan, not resolved, the authors of the impeller are silent. First-night refrigerator! The compressor is blown by the impeller. You will get a motor, remove. It will be useful. Concerning washing machine, Drum let me on the aviation propeller. Plastic tank is suitable to make a housing. Separate seats Warm with a construction hairdryer.

Inspect the blender, supply an unnecessary laser disk that obtained the shape of the impeller. You can make the fan on your own, using pricked materials. It does not require high power, it makes no sense too much, honing items. Believe, readers know how to make a fan with their own hands.

Eternal fan from the processor cooler

We decided to please readers, told how to make a fan. The review is not the first, I had to dig, looking for worthwhile. It looks elegant the idea of \u200b\u200bcreating an eternal fan, spinning forever. Mail.Ru user posted a design looking attractive. Let's see near, thinking along the way, how to make a fan that works forever.

You know, of course, system blocks work quietly (modern models). The slightest noise means: the cooler came down the axis, or it's time to lubricate the aged fan. Work for hours, the days are folded by weeks, the system unit will serve as years. It became possible, thanks to the thoughtful technology. Think, noise depends on the magnitude of the friction force. Energy mechanical becomes thermal, acoustic due to the presence of roughness. Processor coolers are easily rotating, it is worth a pour.

The author of the video - apologize for the lack of name, justify: the roller in English - offers to collect an eternal fan from the accessory. The accuracy of fitting parts is large, the blade spins easily. Costs are reduced to a minimum. The author of the video laid out by the Deirones channel, noticed: The processor fan is powered by a constant current. Page inside, found four coils, equidate around the circumference, axes directed to the center of the instructor.

Inside no switches, it means a paradoxical fact: the field of coils is constant.

If an asynchronous engine of a typical fan is powered by a variable voltage of 220 volts, creating a rotating magnetic field, in our case the picture is permanent. Could say: inside the rotor leads a switch in motion, creating the desired distribution. It is not true, confirmed by the further progress of the author's thoughts, the result of experience. Western innovator decides to replace the coil with a permanent magnet. Indeed, there is no alternating field - why the electric current?

Demonstrately the author cuts off the power wire, the neodymium magnets ( hard disk) Perimeter framework. Each at the continuation of the coil axis. The work is completed, the blades of cheerfully began to rotate. We assume, the principle of sortied by orthodox literature is simply used. Commercial mystery of the patent holder.

The initial movement of the blades is obtained by random air fluctuations. Reminds Magnetron, the oscillation squabbles are caused by the natural chaotic movement of elementary particles. The question arose, which sets the direction of rotation. The design is absolutely symmetry. We decided to figure out, express our observations:

Agree, more convenient than torturing uSB ports, constantly spend batteries. There is an eternal fan from an arbitrary position, deprived of wires. We assume that the power of magnets plays a decisive role. Stops working a simple rule: more - better. Slises golden middle. When the blades are spinning from a random flow of air, overcoming the field of neodymium pieces. Weak magnets probably powerless to keep the steady rotation. The force of the field must be exactly as created by coils under the action of voltage +5 or +12 volts.

Create an eternal fan correctly

Discussed how to make a fan, measure the direction, the power of the magnetic field of coils. Enjoy special devices. Magnetometer, teslameter, formed by a magnetic induction converter, measuring module. When the interaction of the fields, the resulting picture is obtained, called clutch. The converter generates EMF. The size determines the measured power of the magnetic field. How two fingers! Costs 10,000 rubles.

Magnets will be located at a considerable distance from the axis. Coils are much closer. You need to know the change in the picture with the distance. According to the law of the coulon, the force falls inversely proportional to the square of remoteness, it is fair for single charges of an arbitrary sign. The magnetic poles separate in nature are not yet found (it is not possible to create possible), a cube of the distance is introduced into the law. Suppose the removal to the coil from the axis is 1 cm, the perimeter of the diagonal is obtained 10. So neodymium should be stronger than 10 x 10 x 10 \u003d 1000 times, a small coil.

No one obliges to have neodymium magnets perimeter of the fan on the diagonals. Poles lie crosswise. Regulate the effect of exposure overwhelming. Having neodymium magnets in the center of the parties of the fan frame, significantly increase the field strength. Calculate. Suppose the hypotenuse of the triangle with a side of 10 cm is a diagonal. The distance to the center of the square will be equal to 10 / √2 \u003d 7 cm. You see, the ratio from 1000 drops, reaching 7 x 7 x 7 \u003d 343. Weight, desperate to find strong neodymium magnets to create an eternal fan.

Measurement! Compass is suitable (there are custom structures collected with their own hands, for example, http://polyus.clan.su/index/indikatory_magnitnogo_polja_svoimi_rukami/0-52). One coil should be connected to power. Then find the position, the lifted arrow will deflect about 45 degrees (do not like it - take any other azimuth). After start experiment with neodymium. Place a piece on different deletes, seeking the coincidence of the deviation of the arrow with the processor fan coil when using the fan coil. Surely the distance is not equal to the diagonal, half of the part, you will have neodymium breaking, cutting.

Singing one edge in length, carefully break parts about a nail, getting the desired field strength to create an eternal fan. We assume the induction is distributed proportional to the volume. Today they told you intelligibly, how to make a fan with your own hands!

Power supply

Wishing to make a fan with their own hands, sees 3 problems: get the engine, food, make a propeller. Details must be mutually docked. Three problems are solved, you begin to make a fan with your own hands. Today at home the abundance of pulsed power supplies. Think up, it started in the 90s. Gaming consoles, mobile phones, other equipment. Technique breaks, pulse power supplies remain. Voltage is sometimes non-standard, most motors work, feeding any voltage. Just turnover will change accordingly. The house was broken broken appliances - Immediately make the fan yourself.

Homemade fan power supplies

Constantly people try to make a special fan with their own hands. One question more often goes beyond the discussion: a power source. The fan device itself is so obvious, disappeared to stop more. So, it is clear that the batteries today are unthinkable. Will it be able to work for a long time. The answer is no. In the extreme case, take the "Kron", in Soviet times they considered a reliable source of energy. The power supply is bad, power will gradually fall, turns to decrease, the person is annoyed. Important stability without additional effort. There is no small battery 12 volts - get ready: let's start looking how to make the source of the self-made fan energy.

The first, comes to mind: to smoke the computer. It is known, miniature devices are powered by a USB port. Gadgets are recharged. The USB port is a source of inexhaustible energy. The voltage is small, the low-voltage DC motor will be needed. We believe, you can find at home to buy in a shopping store. How much will be the power of the port: according to old standards 2-3 W. Another thing is to find a host device with an updated interface version (2014 declared rarity). The developers promised to give 50 W (even more, hard to believe). True wires will become more, rated voltages will increase. We remind, according to the tradition, the power is fed to red (+), black (-) wires. White, green - signal.

It is clear, it is difficult to expect high power, "even if the port supports, the motor will not pull. It is recommended to take a rash rash. The engine must be powered by a rapid voltage. For example, we recommend using a processor cooler. The supply voltage is less than 12 volts, it simply drops the speed of rotation. Excess Beware - Motor burns.

We are looking for energy, the question is easier solved than for 3 volts:

12 volt power supply for homemade fan with your own hands

We propose not to collect the pulse power supply, do it yourself usual. Recall, the first is distinguished by small-sized transformers. Therefore, the power supply will be relatively large dimensions. It will consist of the following parts:

• A step-down transformer. I do not call the number of turns in advance, the voltage is unknown, rectifting which diodes, we get 12 volts. Of course, you can experiment, like video YouTube about homemade radio receivers, capturing the reader, looking for a ready-made solution.
• Bridge bippetier, adding three three, increase the efficiency. Radioetals do not differ much cost.
• The backbone of the power supply is ready for the homemade fan to serve for a long time, straightening network ripples. After the bridge, turn on the lower frequency filter, the scheme pervertise from the Internet.

At the output, the constant voltage of the amplitude of 12 volts. Try not to confuse the terminals. Where "Plus", where "minus" can be understood by studying the scheme. Below are the picture of the bridge, see, read the explanation. In the radio electronics, the current direction indicates the opposite of the true one. The charges flow, according to believing, in the direction from the plus to minus (towards electrons). Reading the scheme, you will see: the diode, the transistor emitter marked with the arrow, looks incorrectly. In the direction of the movement of positive charges. Each has a mark, in the diagram is denoted by a huge triangle arrow. Therefore, we always learn, "plus", guided by graphic notities given by the drawing.

The drawing shows: plus it will be right, passed according to the diode arrow to the lower terminal of the output. Minus leaves upstairs. For alternating voltage (Roughly speaking) Plus, minus will be alternated to the left-to the right, the name of the rectifier will become understandable - bippetier. Works on a positive part of the voltage and negative. Diodes take power, low-frequency. Solid sizes, scattered power is relatively large. It is possible to calculate, using the uncomplicated formula, taken from the training course of physics. The resistance of the open P-N transition (sheets of the directory) multiply on the current consumed by the engine, we take the stock at least 2 times. The motor body contains an inscription indicating power, can be divided into 12 volt voltage, simply multiply by 2 - 3, take a diode with an equivalent dispersion power (see directory).

Now we calculate the transformer ... I went here http://radiolodka.ru/programmy/radiolyubitelskie/kalkulyatory-radiolyubitelya/, chose the Trans50 program, we will master it. Note, among the software, it is possible to calculate the filter parameters. Do not regret what they gathered to make a fan? Offers choose one of the 5 windings. Steel participates everywhere. You can do, losses will be great. Steel forms a magnetic circuit, the energy gets the secondary winding. It is better to find an old rusty transformer. The time is bad, in the hungry 90s dumps are littered with the plates of the windings surrendered into scrap. There were no problems with winding transformers.

It's time to understand how voltage will need the correct operation of the scheme. The term borrowed from electronics acting the AC voltage is helped. Voltage, on active resistance creates a thermal effect equal constant tension acting amplitude. To obtain the required voltage value on the secondary winding, you need 12 volts to divide by 0.707 (the unit divided by the root of Square 2). The authors received 17 volts. The engineering calculation sins 30% error, take a small amount (part of the amplitude to 1 volt will be lost on diodes).

As for the current of the secondary winding (you need to calculate), type something like "Culera's power" in the search engine. We will do with readers. Smart articles write: Couple consumption current is indicated on the housing. There will be the necessary parameter, we will substitute in the calculator. Secondary winding voltage Author took 19 volts. The voltage drop on the P-N transitions of powerful silicon diodes is 0.5 - 0.7 volts. Therefore, a corresponding stock is needed. Smart heads searched, made a conclusion, the cooler of the processor does not consume over 5 W, therefore, the current is equal to 5 divide by 12 \u003d 0.417 A. We substitute the numbers to the ribbon calculator, for the ribbon core, we obtain the transformer design parameters:

1. Sections of the magnetic pipeline under winding 25 x 32 mm.
2. Window in magnetically wire 25 x 40 mm.
3. The magnetic circuit breeded with a frame under the winding of the wire with a thickness of 1 mM and a cross section of 27 x 34 mm.
4. The wire is wound along the main side of the window, 1 mm from the edges remains a stock, and a total of 38 mm.

The primary winding is formed with 1032 with a diameter of 0.43 mm with a diameter. The approximate length of the wire is 142 meters, the total resistance of 17.15 ohms. The secondary winding consists of 105 turns of copper vein with lacquer insulation with a diameter of 0.6 mm (length 16.5 meters, resistance of 1 Ohm). Now readers understand: the question is from what to make a fan, they begin to solve the core ...

How effective are the proposed technical solutions? Focalla is known to Ancient Egypt. The Clip of Michael Jackson is evidenced, recommending "Remember" (Remember The Time). The plot was hardly made without consulting archaeologists, historical scientists. We want to report, in Mexico most ladies enjoys verses. Spaniards know how to deal with heat, the country lies at the equator. Think ...

The most logical use of a computer fan is not for the purpose is of course the wind generator. Simplicity and availability of a computer cooler inspired many homemade. Idea to create portable charging Its hands for mobile devices does not give rest to many. So the author of this wonderful video language has long wanted to check - what is this turntable?

We take any cabinet fan, the more in the diameter, the better. Many naively believe that its electric motor will immediately turn into a generator, it is necessary to twist it. However, the maximum, to which he is capable of such a performance is to ignite the weak LED. Is this limit? Why so few? To understand the cause, you need to look inside the device. The whole focus is that in such coolers there is a non-micolster engine. It is not structurally adapted to work in the opposite mode as a generator, and that is why: its windings are wound consistently with a double wire, and also opposite to each other, and the magnet poles alternate. Therefore, when rotating a fan in coils, anti-EDC will occur and such a generator will be ineffective.

The first method of reconstruction of the cooler to the current generator

The first way to exit this situation is to try to cure a native motor, that is, rewind the stator with a new wire. Of course, this procedure is very painstaking, but for those who know how to work with their hands - quite sat.
And in educational purposes even useful. The main thing now is to alternate the winding directions on each core. Thus, we will have the simplest single-phase alternator alternator. Between themselves coils are connected consistently. The greater the number of turns and thinner wires, the better. The beginning of the first coil and the end of the latter will be according to the conclusions of our generator. Now you can collect everything and check. But do not forget that the voltage will be variable. Therefore, you need to make a simple rectifier or buy ready.
After all this treatment procedure, the indicators of course improved, but not radically. The reason for this may be both too much a gap between the stator and the rotor and the weak ring magnet. Its actually magnet can be called with a big stretch. Plus, the rectifier still eats from one to two volts. Unfortunately, such a remission did not justify itself.

Second version of the alteration of the cooler in the windmill

Well, we go to the plan "b". Take the usual brush motor from the printer. It is easily turning into a generator without alterations. And thanks to the mechanical collector, when rotating immediately gives constant current. And no rectifiers need. His power is minimal, which is important for a small impeller. However, it should be noted, for effective work it requires high revs, and therefore wind speed. Let's see what will be able to survive from it by conducting a test series. It can be concluded that in the wind at a speed of up to five meters per second, there is nothing to catch at all, but in the range of five to ten meters per second it is quite possible to power a large LED flashlight and in practice to apply for duty lighting of small rooms, corridors, street tracks or As a bench. You can abandon the batteries in a small radio, and if you add a drive in the form of an ionistor in the chain, then a problem with wind gusts and the design will become more practical. If you live in a high-altitude house, it is ideally to place such a wind generator on the balcony and find it your application. But about charging mobile phones with such a windmill, you have to forget. Just not enough power. To dial the voltage is not a problem, what will work the phone diagram and how it would show the charging process, but the current will be at the same time no more than 50 mA with winds about ten meters per second. And this is a meager power. For normal charging you need ten times more. Alas, this is possible only under the hurricane wind. By the way, the big plus of a small windmill is that it is not afraid of strong wind gusts and it does not need protection, and the cheapness and simplicity of design are able to wake up the fantasy much more self-delicacies who are capable of doing wonders with their own hands.
Detailed process of manufacturing a windmill from a cooler from the computer is shown on the video.

Hello everybody! In the network, many schemes of high-voltage generators differ in power, the complexity of assembly, by price and availability of components. This homemade is assembled from practically thrusters, anyone will be able to collect her. This generator was gathered, let's say for informational purposes and all kinds of experiences with electricity. high voltage. Approximate maximum of this generator 20 kilovolt. Since the power supply is not used as a power source for this generator, this is an additional plus in terms of safety.

In the photo, all the necessary details, to build a high-voltage generator.

For the assembly it will be necessary:

Ignition Coil from Vase
Cooler with Hall Sensor
"N" Channel Mosfet
Resistors per 100 ohms and 10 com
Connecting insulated wires
Soldering iron
Terminal block (optional)
Radiator for Mosfta.
Multiple self-sustaining
Plywood base for fastening parts

Who will be interested to try to tell more. The pulse generator uses a cooler cooler from a computer or a similar to 12 volts, but with one condition - it should have a built-in Hall sensor. It is the Hall sensor and will generate pulses for a high-voltage transformer, which, in this case, uses the ignition coil from the car. Select the appropriate fan is very simple, as a rule, it has three inputs.

The photo shows the presence of three conclusions. Standard Coloring This is a red conclusion plus power, black - common (earth) and yellow - exit from the Hall sensor. When power is applied to the outlet fan (yellow wire), we obtain pulses, the frequency of which depends on the rotation of the electric motor of this cooler and the higher the voltage, the higher the frequency of the pulses. Rapid voltage follows in reasonable limits - approximately 12-15 volts, so as not to burn the cooler and the entire scheme. The resulting pulse signal is to be applied to the ignition coil, but it must be strengthened.

As a power key used "N" channel field-effect transistor (Mosfet) IRFS640A is also suitable other with similar parameters, or approximate current 5-10 amps and volt 50 voltage for reliability. Mosfets are present in almost all modern electronic circuits, whether motherboard computer or launcher energy saving lampSo, finding suitable no problems.

The ignition coil from the car VAZ "Classic" B117-A has three conclusions. The central is a high-voltage output, "b +" is a plus 12 volt, and the general "K" - may not be marked.

Initially, the schemes consisted of three components: a cooler, mosfet and coil, but after a short time it was broken, as either mosfet or a mosfet, or a hall sensor. The output is the installation of resistors per 100 ohms to limit the start current from the Hall sensor to the shutter, and the tightening resistor 10k for locking the Mosfet in the absence of a pulse.

When assembling the circuit, the transistor should be installed on the radiator preferably with the use of thermal paste, since the heating is essential during operation.

The connector from the cooler used as a terminal block to connect a mosfet. As a result, the need for a solder of the transistor disappeared, to connect or replace it is enough to connect the block with the outputs of the transistor.

The fan secured on top of the radiator with two screws. As a result, it turned out that the cooler plays a double role - as an impulse generator and as an additional cooling.

Scope of application

Make a wind generator, taking the fan as a basis, would seem to be easier? However, several obstacles will fall on the path of such technical reincarnation. How to overcome them, for which a wind power station made from the fan can be applied and this article will tell.

Immediately it is worth notifying, to expect that the fruit of the work will be the unit, which can be charged with industrial batteries, or it is not worth the buildings. Charging a mobile phone, or the work of a small illuminator on the LEDs - approximately such tasks will be able to solve the wind generator, which is, if you can express it, the product of deep recycling of the fan.

Why are there such similar devices for reincarnation to each other require efforts? This is technical explanations that will be able to consider.

Differences

Features of the design of electric motors and generators

The movement of electrons, electric current, occurs in the conductor under the influence of a changing external magnetic field. Electrical motors are similarly arranged, only in the reverse order - on moving charged particles in the magnetic field the force acts, which causes the conductor to change its position in space, i.e. leads to the movement of the rotor.

Both in the generators and in the engines, this magnetic field is created in the stator, or in the rotor, depending on the model, permanent magnets or electromagnets (excitation windings). If the motor attracts iron items - it is on permanent magnets. This option is optimal from the point of view of using it as a generator, since it does not require any modernization.

"Application to obtain electricity engine with excitation windings will be more complicated, because it will have to provide the power of these most windings. And this will noticeably complicate the design. "

So actually the automotive generator works. On the rotor through the "tablet", brushes and contact rings are served 12V. Together with the rotor rotates the magnetic field created by it. It creates an electric current in the stator winding (of course, current is produced more than spent, otherwise you need a generator).

When the battery is fully charged, and powerful consumers are turned off, the current on the rotor is almost no applied and the generator rotates in good. And using the autogenerator as a wind power station, this current will have to submit and control its parameters.

Sometimes it is proposed for such a case to remove windings from the rotor and instead of the wire inclusted the niordic permanent magnets (in this case, the current is not needed), but this is a topic for a separate article.

Features of geometry blades

Since the design of the fan corresponds to the target - push the mass of air, and, on the contrary, are given in the movement of the currents of the air masses, then the geometry will differ slightly. The angle of attacks of the blades of both types varies little.


The closer to navigate to the center - there are differences.

Wind electrostation screw:

The area of \u200b\u200bthe blade at the center practically does not participate in the development of energy, as it moves many times more slowly than the entire blade, so it is done with an angle of attack equal to zero so that the air masses can calmly pass without creating congestion. A fixed fan needs in changing the angle of attack the blades is not.

Since the general geometry is similar, the propeller of the fan will work both as a wind generator.

Rotational speed

It is unlikely that at least one fan under the influence of the wind will give the same revs as being included in the network. Therefore, it is not necessary to hope that the wind generator, 100 watt, made from the 12V fan, will give the same voltage and will ensure the operation of consumers 100 watts.

Examples of manufacture

From the children's toy fan on batteries

Such a wind generator is easier than simple. The toy uses an electric motor most often by 1.5 or 4.5 volts with an independent excitation from permanent magnets. There is a finished screw. You need to get the batteries, to the contacts + and - connect the wires, place the fan into the air flow, turn on, and can be measured on contacts the characteristics of the current generated.

In order for such a wind generator to work better, the screw blades will not prevent add power, for example, overlays cut from plastic pipe in the form of petals. Well, you will have to provide the unit with some other binding elements for electrical lading.

The fan will have to be protected from precipitation with a special casing and fasten on the movable frame. Movable fastening of the frame to the mast must include a contact-brush mechanism (you will not pass the current without it). The opposite end of the frame is supplied with a stabilizer, its task is to deploy the wind generator towards air flow.

What can be counting on if the engine is 4.5V, it is 2.5 ... 3V maximum, not enough even for charging the phone (usually 5V). But the diet of the LEDs, for example, can designate the boundaries of the entrance gate, or illuminate the boundaries of the garden path, such a device with sufficient wind is quite capable of providing.

From the processor cooler fan (cooler)

This fan is most often the engine 12V, as in the previous example on permanent magnets and turning it into the wind generator in the same order.

The differences are that:

• the blades of the cooler initially do not go anywhere - the propeller is needed new;
• the current produced at a certain wind speed is quite enough to charge the android or 5B tablet (the use of the controller in this case cannot be avoided and the usual automotive is suitable charger).

Car engine cooling fan cooling

The option is more complicated, but if previous options were originally considered as toys, then this design could be quite tangible return. The wind generator under consideration can serve, for example, to charge the battery 12V. Spare in battery electricity, skipping 12/220 through the 12/220 converter, can be used as a home network.

The design uses the engine from the 24V fan. The blades are shortened, leaving only the fragments needed for the attachment of new PVC-cut from the PVC tube (use for these purposes the PVC bottle will not work - due to the low stiffness they will be simply flexing with wind).

Cut the blades about this template as in the photo.


The number of blades can be any, most often used options 3, 4 or 6.

The wind generator is composed of the classic scheme (Fig. 3). The voltage, which produced with a moderate 4 ... 7 m / s, will be greater than 12V, which will allow charging the battery. IN electric chain A diode must be added so that in the absence of the wind, the power plant has not turned into a fan on the mast.

The battery charging controller is not prevented and the charging current and the discharging chain at the end of the charge. You can do without it, but then you have to constantly monitor the charging process and adjust it manually.

If there is a house, an old cooler from the computer, you can build an excellent wind installation that will produce electricity. The mini wind generator is an excellent thing, especially for the terrain with frequent and strong winds. On the peculiarities and technology of its manufacture, we will find out further.

How to make a mini wind generator with your own hands

Starting work on a mini wind generator follows from the manufacture of the drawings of the future wind installation. In addition, materials should be prepared as:

• a thick bottle of plastic;
• an old cooling cooler or fan, from its sizes and power, the power of the generator itself directly depends;
• low-current wire in the amount of 5-8 meters;
• wooden timber, the cross section and the dimensions of which are determined individually;
• two steel pipes that come alone in one;
• diodes;
• epoxy and super glue and super glue composition;
• fasteners in the form of protracted ties;
• old SD disk.

First of all, you need to get started with the search for a suitable cooling mechanism. We offer to use the cooler from the old computer. Initially, the cooler is disassembled, its propeller part is on the electric motor. Most often, it is fixed on the lock ring, it is under the rubber seal. After dismantling the annular seal, remove the blades on the fan.

Next, the process of soldering cables that ensure the operation of the generator installation. On copper coils of the fan there are two connections for wires, they are connectors on the coils. One of the plots is distinguished by the presence of a connected wire from copper, and the second has two wires. Two wires are connected to the legs of one wire by soldering.

At the next stage of creating a small wind generator, a rectifier is created. The main function of this instrument is the transformation of AC to the constant. For these purposes, it will require four diodes, they are trimmed in such a way that one pair from the black mark remains with a 10 cm segment. The long end of the diode is bended, so it will be a P-shaped connection. All diodes are connected by the method of soldering. To test the wind generator, connect the diodes to it if the LED works, the wind generator functions correctly. The outer plastic part of the cooler is removed, to process all irregularities, use the knife.

This is followed by the process of manufacturing the blade of the wind generator. For the manufacture of blades, use an old bottle, for example, from under shampoo. The top and bottom of the bottle are cut. It turns out a cylindrical product product, it must be cut along. Pre-make a drawing in the form of blades, according to him, cut out from the bottle of blades for the wind generator. Note that the final part of the blades should be cut at an angle of one hundred and twenty degrees. Next follows the process of fixing blades on the cooler.

At the next stage, the manufacture of a windmill shank is performed. To fix the motor, a timber made of wood is used. Its rotation is performed using steel tubes. For the manufacture of a shank, use an unnecessary disk. The wooden bar is equipped with a pass-through hole, its diameter should be slightly larger than the diameter of the steel pipe. With not a dense installation of the tube, fix it with an epoxy-based adhesive. On the end part of the bar is equipped with a cut for the installation of the disk. The location on which the motor with Bru is connected, it is also necessary to be treated with adhesive composition. Wires and soldering, it is also recommended to coat with glue to prevent corrosion.

Next follows the process on which the support is manufactured. For its facilities, use two tubes. One of them is fixed on a wooden bar, and the second is installed in the ratio with the rotation. For their connection, you can use bearings, and use fluoroplast to improve sliding.

Mini wind generator with your hands from the motor

We offer an option to make a wind generator from a motor from an old printer. This model differs in average performance and works, even at the slightest wind. A battery will also need a battery for the winder, the maximum power of the device is 100mA.

As the main detail of the windmaster, a motor is used, from a non-working jet printer. Pre-printer must be disassembled and remove the motor from it.

For locks, the blades use the transistor. It must be drilled in the ratio with the size of the shaft installed. Next, all parts are fixed with an adhesive composition on an epoxy basis. In addition, with this composition, the protection of particularly important parts of the device from moisture and weather is ensured.

Using a segment of a plastic pipe, a diameter of about 12 cm, cut the blade for the windmill. For these purposes, a cutting machine is used. The optimal value width value is 90 mm, the holes are constructed by a special device, and then the shaft is installed on the generator motor using screw connections.

As the basis for the manufacture of the windmaster, a pipe with a diameter of 55 mm is used. For the manufacture of the tail, use Phaneur. The motor is installed inside the pipe, then the construction of the rectifier is performed. Since the motor does not reproduce a large amount of electricity with a small wind. Thus, it is possible to apply the doubling scheme included in series.

The scheme is installed in the plastic bag and is installed in the pipe along with the rectifier. Next, the motor fixation is performed using wire. In addition, all holes are closed with a silicone pistol. One hole is used for water drain, and the second for evaporation of condensate masses.

To fix the tail of the wind generator uses a bolt and wire. Thus, it will be possible to securely fix the installation. Follow the rigidity of the compounds obtained.

In order to build a mast to install a windmill, use bars interconnected using self-tapping screws. Fix the windmill on the mast and install the preset place. With this installation, it is possible to charge a mobile phone or organize backlight.

Make a mini wind generator with your own hands

Before starting work on the wind generator, it is necessary to determine the amount of winds in your climatic region. Serious green - windless zones imply the use of exclusively sailing type wind generators. If necessary, to provide a DC, it adds a device in the form of a buster. This device Performs the function of the rectifier, and also stabilizes the voltage. It will also require the presence of a charger, high-power battery, converter. The cost of manufacturing this installation is extremely high and not always justified.

In zones with weak winds designated by yellow, a variant of the manufacture of a low-speed wind generator is possible. These devices are characterized by good performance.

For windy regions, any wind installations will be suitable. Most often, vertical type devices are used or sailboats.

In order to perform calculations to determine the power of the wind installation, it is necessary to take into account such factors as:

• constant wind speed in a particular region;
• the air is a solid medium, so the capacity of the wind generator depends on the quality and performance of the rotor;
• air flows possess kinetic energy.

We propose to consider the features of sailing wind generators. These devices are made of wear-resistant material, which is perfectly opposed by the winds. If you decide to make such an installation yourself, then it is necessary first of all, to conduct a number of calculations associated with these instruments.

As a material for the manufacture of the wind generator, you can use the various glands that have been lying at your home. The most expensive element is a battery. Its power determines the size of the installation and its performance.

The self-made axial-type wind generator is quite simple to manufacture at home. Start work with mast. For its manufacture, the pipes are most often used, they should be different in diameter. To connect pipes with each other, a welding machine is used. The mast is installed on a slaining platform. At the same time, several meters are deepened to the ground, to obtain a sustainable design. On separate parts of the installation, you need two magnets, for a stronger fixation, they are additionally poured with epoxy resin.

Then follows the process of making shape and plywood. For these purposes, coils interconnected by the phase are used. The process of manufacturing a stator looks in this way: a wax paper is installed on the previously cut square from plywood. The installation of plywood should be installed on which the holes for the installation of the stator are pre-cut. Next follows the process of mounting a mug of fiberglass and coils are installed.

After that, the finished stator from the previously prepared form is made. A duralumin pipe is used for the manufacture of the screw. The screw is manufactured in a diameter of one meter. For cutting blades, use an electric jigsaw. In the central part of the installation, equip the hole with which the screw on the generator will be fixed.

The wind generator has a tail element displaced to the axis. With severe winds, the wind is pressure on the surface of the wind generator and it shifts to the side. This scheme allows you to protect the device from strong winds. This wind generator model allows you to produce a sufficient amount of energy to ensure the street lighting of the house. It is not difficult to make the wind generator, the main condition for obtaining a high-quality device is a comparison of the wind force in your region with its power.

Production technology of mini wind generator with their own hands

For the manufacturer of manufacturing you need a minimum supply of tools and materials. We offer an option for the construction of a mini wind generator for giving. This device is able to provide a small house with a minimum amount of electrical appliances.

For the manufacture of such a wind generator, it will be necessary primarily for the disc on which magnets are installed. Next follows the process of winding copper coilswhich are poured with a resin. To perform rotation, the generator is installed on the previously provided basis.

These wind generators are characterized by good performance and quality work. The ratio of the magnet with poles is two to three, if the wind generator has two phases, for a single-phase device, a ratio one to three is sufficient. All poles relate to each other depending on the coils used.

The power of the wind generator is determined primarily by the dimensions of the magnets used in its design. As a mast under the generator is enough to use a steel pipe or logs. Batteries do not necessarily use new, and any appliances suitable for power.

It is possible to make a variant of several wind generators at the same time, each of them will perform certain functions - one provides a dwelling with light, the second is responsible for the operation of the TV, and the third is for night lighting.
