Do-it-yourself ventilation deflector. Homemade wind generator for home and garden: principles of operation, schemes, what and how to do Final assembly and installation

It is difficult not to notice how the stability of electricity supplies to suburban facilities differs from the provision of urban buildings and enterprises with electricity. Admit that you, as the owner of a private house or cottage, have repeatedly encountered interruptions, inconveniences and damage to equipment associated with them.

The listed negative situations, together with the consequences, will no longer complicate the life of lovers of natural spaces. And with minimal labor and financial costs. To do this, you just need to make a wind power generator, which we describe in detail in the article.

We have described in detail the options for manufacturing a system that is useful in the economy, eliminating energy dependence. According to our advice, an inexperienced person can build a wind generator with his own hands House master. A practical device will help to significantly reduce daily expenses.

Alternative energy sources are the dream of any summer resident or homeowner whose site is located far from the central networks. However, when we receive bills for electricity used in a city apartment, and looking at the increased tariffs, we realize that a wind turbine designed for household needs, we would not interfere.

After reading this article, perhaps you will make your dream come true.

Wind generator - perfect solution to provide a suburban facility with electricity. Moreover, in some cases, its installation is the only possible way out.

In order not to waste money, effort and time, let's decide: are there any external circumstances that will create obstacles for us in the process of operating a wind turbine?

To provide electricity to a summer house or a small cottage, it is enough, the power of which will not exceed 1 kW. Such devices in Russia are equated to household products. Their installation does not require certificates, permits or any additional approvals.

The issues of energy independence disturb the minds not only of heads of states and enterprises, but also of individual citizens, owners of private houses. With increasing monopoly and tariffs by electricity producers, people are looking for efficient alternative power sources. One of these sources is the wind generator.

The main elements in the wind generator system

There are many models, options from different manufacturers, but as practical experience shows, they are not always affordable in terms of price and quality for a wide range of consumers. If you have information, certain knowledge of electrical engineering and practical skills, it is possible to make a wind generator with your own hands.

Principle of operation and main elements

The work of a home-made wind generator is no different from industrial models, the principles of operation are the same. Wind energy is converted into mechanical energy rotation of the rotor of the generator, which generates electricity.

The main structural elements (fig. above):

• propeller with blades;
• a rotation shaft through which torque is transmitted to the generator rotor;
• generator;
• generator fastening design at the installation site;
• if necessary, to increase the rotational speed of the rotor, a gearbox or belt drive can be installed between the propeller shaft and the generator shaft;
• to convert the alternating current of the generator into a direct current, a converter is used, a rectifier diode bridge, the current from which is supplied to recharge the battery;
• battery, from which electricity is supplied through the inverter to the load;
• inverter converts D.C. battery with a voltage of 12 V or 24 V AC with a voltage of 220 V.

The designs of propellers, generators, gearboxes and other elements may differ, have various characteristics, additional devices, but the listed components are always present at the heart of the system.

Choosing and making your own hands

According to the design, there are two types of axis that rotate the generator rotor:

• generators with a horizontal axis of rotation;

Horizontal axis generator

• generators with a vertical axis of rotation.

Rotary wind generator with a vertical axis of rotation

Horizontal axes of rotation

Each design has its own advantages and disadvantages. The most common option is with a horizontal axis. These models have a high efficiency of converting wind energy into rotational movements of the axis, but there are certain difficulties in calculating and making the blades with your own hands. The usual flat shape of the blade, which was used in ancient windmills, is ineffective.

To use the maximum wind energy when the axis rotates, the blades must be wing-shaped. On airplanes, the shape of the wing, due to the force of the headwind, provides lifting flows. In the case under consideration, the forces of these flows will be directed to the rotation of the generator shaft. Propellers can be with two, three, or more blades, the most common designs with three blades. This is quite enough to provide the required rotation speed.

Wind generators with a horizontal axis of rotation must be constantly turned by the plane of the propeller to the front of the oncoming wind flow. This requires the use of a vane-type tail unit, which, under the influence of the wind, like a sail, deploys the entire structure with a propeller to the headwind.

Vertical axes of rotation

The main disadvantage of this option is low efficiency, but this is offset by a simpler design that does not require the manufacture of additional elements to turn the blades to the wind. The vertical arrangement of the axis and blades allows you to use wind energy to rotate from any direction, this design is easier to do with your own hands. The rotation of the shaft is more stable, without sudden jumps in speed.

The average annual wind speeds in Russia are not the same. The most favorable conditions for the operation of wind turbines are 6-10 m/s. There are few such areas, mainly winds of 4-6 m/s prevail. To increase the rotation speed, it is necessary to use gearboxes and take into account the height, the wind rose in the area where the generator is installed.

An example of the manufacture of a wind generator

A variant with a vertical axis of rotation is being considered.

DIY wind turbine

The easiest option for the production of blades is to use metal barrel for 50-200 l. Depending on the number of blades required, the barrel is sawn by a grinder from top to bottom into 4 or 3 equal parts.

Vertical blades from a metal barrel

You can simply use sheets of galvanized roofing iron, which are easy to cut into the desired shape with your own hands using metal scissors.

Vertical blades made of sheet metal

In the future, the blades are mounted on the upper part of the axis of rotation. The basis for their fastening can be wooden disks made of six-layer plywood.

It is more reliable to use a metal frame made of a rectangular profile, to which the blades are bolted.

An example of the placement of vertical blades

An example of attaching the blades to the platform

The frame or discs are rigidly attached to the axis of rotation, the axis itself is inserted into couplings with bearings that are securely installed in the frame of the tower or roof of the building on which the generator is located.

Installing the axle with blades on the tower

2. Axle stabilization platform with double row ball bearing.
3. Stretching steel cable Ø 5mm.
4. Vertical axis, steel pipe Ø 40-50mm, wall thickness not less than 2mm.
5. Speed ​​control lever.
6. The blades of the aerodynamic regulator are made of plywood or plastic 3-4 mm thick.
7. Rods that regulate the speed of rotation, the number of revolutions.
8. A weight whose weight determines the speed of rotation.
9. Vertical axle pulley for belt transmission, widely used bicycle rim from wheel, without tube and tire.

• Support bearing.
• Pulley on the axis of the generator rotor.

A pulley for a belt drive or a gear for a gearbox is attached to the lower end of the axle, this is necessary to increase the speed of rotation of the rotor. Practice shows that at a wind speed of 5 m / s, the rotation of the shaft with horizontal blades from the barrel will be no more than 100 rpm. At a wind speed of 8-10 m/s, the rotation reaches up to 200 m/s. This is very little for the generator to produce the necessary power to charge the battery.

Reducer ratio 1:10 allows you to achieve the required speed.

Installation of belt pulleys

Low speed generator

To convert mechanical rotational energy into electricity, the easiest way is to use automotive alternators. But conventional generators cars for windmills are not recommended due to the presence of brushes in their design. Graphite brushes remove the current induced on the rotor, during operation they are erased and require replacement. In addition, such generators are high-speed, 2000 or more revolutions are required to generate a voltage of 14 V with a current of up to 50A.

More efficient generators for windmills from tractors and buses Г.964.3701 with magnetic winding excitation. They do not have brushes, they work at lower speeds. The G288A.3701 generator has three phases and is used to power vehicles in conjunction with a battery. It has good performance for use in wind turbine systems:

• generates a voltage of 28 V;
• built-in rectifier delivers direct current up to 47 A;
• output power up to 1.3 kW;
• idle rotation 1200 rpm;
• with a current load of 30A, 2100 rpm is required.

The generator has suitable dimensions and weight:

• total weight 10 kg;
• diameter 174 mm;
• length 230 mm.

Generator with MAZ - 24V

Generators of this type are used in KAMAZ, Ural, KRAZ, MAZ vehicles with engines from the Yaroslavl plant YaMZ 236, 238, 841, 842 and ZMZ 73. In order to save money, you can buy a used generator at dismantling points. To generate more power at low speeds, you can make a generator with your own hands on neodymium magnets, but this is a separate issue and requires a more detailed description.

Assembly sequence

1. First of all, a tower or generator mounting structure is mounted on the roof of the building. The vertical axis is attached to the bushings with bearings, the blades are installed.

1. After installing the axle with blades, a pulley for a belt drive is fixed on the lower part.
2. At the level of the axle pulley, to a specially prepared platform, a generator is attached with a pulley for a belt on the rotor shaft. Alternator pulleys and vane axles must be installed at the same level.

The diameter of the pulley on the axle should be approximately 10 times the diameter of the pulley on the alternator shaft. Based on the conditions that the calculated wind speed is approximately 10 m / s, it will give an axis rotation speed of up to 200 rpm.

The formula used is:

Wr = Wos x Dosd, where

• Wr is the rotation speed of the generator pulley;
• Dos is the pulley diameter on the vertical axis;
• d is the diameter of the pulley on the generator rotor shaft;
• Wos is the rotation speed of the vertical axis pulley.

Wr \u003d 200 rpm x 500mm / 50 mm \u003d 2000 rpm - sufficient rotation speed for the generator of the selected type to produce the required power.

1. The belt is tensioned; for this, there should be slots in the generator mounting platform, as on a car mount.
2. The output wires of the generator are connected to the battery terminals.

These generators have built-in rectifiers, the output is direct current, so the positive red wire is attached to the “+” terminal, and the negative wire is attached to the “minus” terminal.

1. The 24V/220V inverter input is connected to the battery, also with polarity.
2. The inverter output is connected to the load circuit.

Video. Wind generator with your own hands.

Having necessary materials, practical locksmith skills, using ready-made car generators with magnetic winding excitation, it is easy to install a wind generator with your own hands. For the manufacture of a generator of greater power on neodymium magnets, deeper knowledge in electrical engineering and skills in assembling electrical equipment will be required. This is one of the most simple ways assemble a wind generator with your own hands.

An important condition for the full functioning of the furnace is normal traction, which will help to remove combustion products. This indicator is strongly influenced by the diameter of the chimney. If it is of a small cross section, then the products of combustion will not be able to go outside and will begin to accumulate inside the housing. In the case of using a wide chimney, cold air flows will not allow burnt substances to rise. All these and other nuances can be compensated by a traction booster, which can really be done independently.

Traction enhancement options

There are several types of devices that can increase the outgoing air flow. Among them, the most popular are:

• Deflector . Structurally, it increases the diameter of the chimney at the outlet.
• . A device that is installed on the top of the chimney (turns against the wind), protecting its mouth from dust and protecting it from various precipitation.
• Smoke fans . Most often they are installed on a fireplace chimney with a small cross section. They can be turned on when there is not enough natural wind flow.
• Rotary turbines . Such devices are installed on the head of the pipe to provide free access to the wind. They are best applicable for gas boilers.

But the simplest and no less effective is to extend the chimney pipe. This increases the difference in air pressure and increases thrust. Usually flue pipe goes a height of 5 meters (this distance includes the vertical section of the chimney, excluding knees, slopes and narrowings).

If the roof has a sharp slope or large objects are located near it, then these circumstances worsen the draft, which will help overcome the increase in the length of the chimney. But with a very long pipe, there may be heat losses, which will go not to heat the home, but to heat the cold street air. To prevent this from happening, special dampers are provided in the furnace that regulate the amount of exhaust gas.

Do-it-yourself deflector installation

The device optimizes air removal, being a reflective device. It will not be difficult to do it yourself - just arm yourself essential tool and purchase sheets of galvanized metal. Their thickness should be no more than 1 mm.

The simpler the design of the deflector, the more accurate the drawings and more efficient device. You don't need to come up with an intricate shape. For example, the most elementary scheme is taken. Dimension D is the diameter of the pipe with a small gap so that the deflector can be securely fixed on it. Di - twice the cross section of the chimney.

Required tools:

• roulette;
• electric drill;
• clamps;
• hammer;
• square;
• metal scissors, hacksaw or grinder;
• riveter;
• heat-resistant mastic;
• self-tapping screws;
• fastening parts.

After preparing the tool, you can start working:

1. Apply the dimensions of the workpieces to the sheet of metal. Cut them out.
2. Roll the future body of the nozzle into a ring and fasten its edges with rivets or self-tapping screws.
3. Assemble the chimney cone in the same way.
4. Combine both items. For better sealing, treat their joints with mastic.
5. Build a metal umbrella and fasten it on top of the deflector with studs or rivets if it is made on the legs.
6. Strengthen the stability of the structure by applying clamps.

The result should be a durable traction booster that can withstand wind and precipitation.

Wind vane to increase traction

This amplifier, unlike the previous one, can rotate around the chimney. The principle of operation of the device lies in its response to air currents, as a result of which, from any breath of wind, the traction amplifier takes the appropriate direction. Air is blown into special gratings, which creates a constant vacuum in the pipe.

The demonstrated product can work in any weather conditions. It reacts even to the slightest breeze. The invented device improves the efficiency of the combustion boiler by about 20%. If you install it on a pipe, then you will not need to make the chimney very long, you can shorten its visible part above the roof.

The weather vane is an exhaust product for the ventilation system, therefore it can be used for multi-apartment and private houses. He gained particular popularity when installing gas boilers. The device not only enhances traction, but also prevents the attenuation of the boiler.

Electric fans

Powerful fans that are used for fireplaces and wood-burning stoves. They are designed to work in a hot environment, where there is a lot of ash and other combustion products.

The body of such devices is made of galvanized steel with a specially applied polymer coating, which provides it with protection from aggressive environments. It has a protective grill that prevents various large and medium-sized objects from entering the air duct.

Works ventilation device from a single-phase motor, which can ensure the uninterrupted operation of the system in any weather. Although it has protection from the flow of hot air, it is placed outside the zone of its movement for safety reasons. It has ventilation holes and a special wheel that prevents soot and dust from sticking.

Such a ventilated system is fully automated. It has built-in temperature sensors, as well as their counterparts that regulate the strength of the air flow. They are triggered by deviations in the operation of the electric motor and create the optimal traction of the device.

Their principle of operation is similar to the deflector - they are also located at the top of the pipe and use wind energy. The nozzle, on which the grids with wings are located, rotates in one direction, regardless of the direction of the wind. Due to its movement, it creates the necessary air rarefaction. The design of the device resembles a dome and is able to protect the chimney from debris and precipitation. It is designed for gas boilers and ventilation ducts. Not recommended for solid fuel boilers and fireplaces.

In calm weather, this amplifier does not work, but in the summer, when the boiler is not functioning, it can create a very strong draft, which is often superfluous.

Description and scheme of operation of the traction amplifier (video)

In the next video, experts will talk about the amplifier, as well as the scheme of its operation. At the same time, they will indicate the advantages of this method of removing combustion products.

Which of the proposed devices to choose will help to decide the very design of the chimney channel and the type of boiler that heats the home. They can be resorted to if it is impossible to increase the length of the pipe.

A set of necessary communications to ensure comfortable conditions in a building of any purpose includes, among other things, the installation of a ventilation system. Ideally, it should be non-volatile - this is very important in modern conditions without stopping rising energy prices. That is why even at the design stage of communications, natural ventilation is primarily considered. At the same time, the correct approach to the technological solution of the system is a rotary deflector integrated into the ventilation duct.

No problems with traction

The purpose of any ventilation system is to remove polluted air, excess moisture from the premises, that is, to ensure normal air exchange. This will take place if the ventilation duct functions efficiently and correctly - the draft in it is excellent. If there are problems in this regard, then they are often provoked by rain, snow, and wind masses entering the canal mine. Also, poor draft can be caused by an incorrect location of the ventilation pipe, its insufficient height, or an incorrectly selected duct diameter. Such shortcomings of natural ventilation are designed to eliminate the installation of a rotary deflector.

Reference. The rotational deflector has other names - a turbo deflector or a rotary turbine. This is a complex mechanism with a rotating part - an active head, equipped with a special system of blades. Also in the design there is a static part - the base, to which the head is attached and connected to the ventilation pipe.

Advantages of a rotary deflector

• Regardless of the direction of the wind, the rotational movements of the active head occur in the same direction. As a result, the effect of a "partial vacuum" in the ventilation duct is obtained - the air is rarefied, the force of the flow increases, and the risk of reverse draft approaches zero.
• Rotary models completely eliminate the effect on ventilation efficiency external factors- Precipitation and gusty winds.
• The autonomy of the functioning of a mechanical device that increases the performance of the air exchange system is one of its most important advantages.
• Low costs for modernization of ventilation.
• Fast return on investment for the installation of a deflector with turbines.
• Protecting the ventilation shaft from debris, birds, etc.
• Decorative completeness of the pipe brought to the roof - any facade benefits from the presence of such a spherical object.

Important! The rotary deflector increases the efficiency of a standard natural supply and exhaust ventilation system by 2-4 times. At the same time, "amplification" does not require a connection to the power supply, which corresponds to current trends energy efficiency of buildings and structures.

What are the disadvantages of a turbo deflector

The rotational design is weather-dependent - this is actually its only, but very important minus. In calm weather, a turbo deflector is essentially no different from a conventional protective visor on an air duct.

Is it possible to make a rotary deflector with your own hands

Simpler types of deflectors, which have been used in practice for a long time, are often made by skillful householders on their own. In principle, a technically savvy person can cope with this work. True, for this it will be necessary to develop a working drawing of the future design, correctly take measurements, and develop a deflector mounting scheme.

Regarding the turbocharged variation, not everything is so simple - it is technically a more complex design. Therefore, almost always, having decided to use a rotational model, they purchase it in the form of a professionally made product.

What the market offers

Turbovent

The model range of rotary deflectors of this brand is represented by models of different geometric shapes, in terms of the immovable base:

• A - round pipe;
• B - square pipe;
• C - square flat base.

Marking of products in the range is presented as TA-315, TA-355, TA-500. The digital index indicates the diameter of the round or the parameters of the rectangular bases. It is from them that one can judge the dimensions of the mechanism, as well as the scope of its application. For example, TA-315 and TA-355 are relevant when organizing air exchange in the under-roof space. But TA-500 is a universal device and can be integrated into the ventilation of a residential building.

The rotary deflector "Turbovent" is produced in Russia - in the Nizhny Novgorod region, in the city of Arzamas.

Rotovent

Polish made stainless steel deflectors. Suitable for roofs of any configuration. Products are made of high quality stainless steel. Universal devices - suitable for both ventilation systems and chimneys. The limiting indicator of the operating temperature is 500 C.

Turbomax

Rotary deflector manufactured by a company from the Republic of Belarus. The manufacturer positions its products as a rotating chimney hood Turbomax1. But it is also suitable for ventilation. Without fear, it can be used in areas with II and III wind load zones. The company draws the attention of consumers to the fact that they are ready to manufacture a product to order according to the parameters for a particular object.

Mounting Features

The factory turbo deflector is a one-piece design, ready for installation. It has an active movable top and a base that incorporates zero drag bearings. The product is thought out in such a way that even with a strong gusty wind it will not tilt and will not be blown down.

Attention! During installation, it is important to take into account that the deflector of any modification should rise 1.5-2.0 m above the roof. Subject to this device, the thrust in ventilation duct will further intensify.

In conclusion, we want to note that rotary deflectors in their segment are the most expensive. At the same time, the consumer is invited to choose a suitable design made of stainless steel, galvanized or structural steel with a protective polymer coating, the color of which can be matched to the facade design. Of course, the type of material from which the deflector is made is reflected in its cost.

I found this detailed design of a Savonius-type rotary wind generator on this wonderful site here http://mirodolie.ru/node/2372 After reading the material, I decided to write about this design and how everything was done.

How it all started

The idea to build a wind turbine originated back in 2005, when a plot was obtained in the family estate of Mirodolie. There was no electricity and everyone solved this problem in their own way, mainly due to solar panels and gas generators. As soon as the house was built, the first thing to think about was lighting, and a a solar panel 120 watts. In the summer it worked well, but in winter its efficiency dropped significantly and on cloudy days it gave a current of only 0.3-0.5A / h, this didn’t suit me at all, since even there was barely enough light, and it was also necessary to power the laptop and other small electronics.

Therefore, it was decided to build a wind generator to use wind energy as well. At first there was a desire to build a sailing wind generator. I liked this type of wind turbines very much, and after some time spent on the Internet, a lot of materials on these wind generators have accumulated in my head and on my computer. at least five meters.

It was not possible to pull a large wind generator, but still I really wanted to try to make a wind generator, at least of low power, to charge the battery. The horizontal propeller wind generator immediately disappeared because they are noisy, there are difficulties with manufacturing slip rings and protecting the wind generator from strong wind, and it is also difficult to make the correct blades.

I wanted something simple and low-speed, after watching some videos on the Internet I really liked Savonius-type vertical wind turbines. In fact, these are analogues of a cut barrel, the halves of which are moved apart in opposite directions. In search of information, I found a more advanced type of these wind turbines - the Ugrinsky rotor. Ordinary Savonius have a very small KIEV (wind energy utilization factor), it is usually only 10-20%, and the Ugrinsky rotor has a higher KIEV due to the use of wind energy reflected from the blades.

Below are illustrative pictures to understand the principle of the robots of this rotor

Scheme for marking the coordinates of the blades

>

KIEV of the Ugrinsky rotor is declared as high as 46%, which means it is not inferior to horizontal wind turbines. Well, practice will show what and how.

Blade manufacturing.

Before starting to manufacture the rotor, we first made models from beer cans of two rotors. One model of the classic Savonius, and the second of Ugrinsky. On the models, it was noticeable that the rotor of Ugrinsky works noticeably at higher speeds in comparison with Savonius, and a decision was made in favor of Ugrinsky. It was decided to make a double rotor, one on top of the other with a 90-degree turn in order to achieve a more even torque and a better start.

The materials for the rotor are the simplest and cheapest. The blades are made of 0.5mm thick aluminum sheet. Three circles are cut out of 10mm thick plywood. The circles were drawn according to the drawing above and grooves were made 3 mm deep for the insertion of the blades. The fastening of the blades is made on small corners and pulled together with bolts. Additionally, for the strength of the entire assembly, plywood discs are pulled together with studs along the edges and in the center, it turned out to be very rigid and durable.

The size of the resulting rotor is 75 * 160 cm, about 3,600 rubles were spent on rotor materials.

Generator manufacturing.

Before making the generator, there were many searches for a ready-made generator, but there are almost none of them on sale, and what can be ordered via the Internet cost decent money. Vertical wind generators have low speed and on average for this design about 150-200 rpm. And for such revolutions it is difficult to find something ready and not requiring a multiplier.

In search of information on the forums, it turned out that many people make generators themselves and there is nothing complicated about it. The decision was made in favor of a homemade generator on permanent magnets. The classic design of an axial generator with permanent magnets, made on a car hub, was taken as a basis.

First of all, neodymium puck magnets for this generator were ordered in the amount of 32 pieces 10 * 30mm in size. While the magnets were being made, other parts of the generator were being made. Having calculated all the dimensions of the stator for the rotor, which is assembled from two brake discs from a VAZ car on the rear wheel hub, coils were wound.

A simple manual machine was made for winding coils. The number of coils is 12, three per phase, since the generator is three-phase. There will be 16 magnets on the rotor discs, this ratio is 4/3 instead of 2/3, so the generator will turn out to be quieter and more powerful.

A simple machine was made for winding coils.

The locations of the stator coils are marked on paper.

To fill the stator with resin, a plywood mold was made. Before pouring, all the coils were soldered into a star, and the wires were led out through the cut channels.

>

Stator coils before filling.

A freshly cast stator, before pouring, a fiberglass circle was laid on the bottom, and after laying the coils and pouring epoxy resin a second circle was laid on top of them, this is for extra strength. Talc is added to the resin for strength, which makes it white.

The magnets on the disks are also filled with resin.

And here is the already assembled generator, the base is also made of plywood.

After manufacturing, the generator was immediately twisted by hand on the subject volt-ampere characteristic. A 12 volt motorcycle battery was connected to it. A handle was attached to the generator and looking at the second hand and rotating the generator some data was obtained. On the battery at 120 rpm it turned out 15 volts 3.5A, the strong resistance of the generator does not allow to spin it faster by hand. Maximum idle at 240 rpm 43 volts.

Electronics

>

For the generator, a diode bridge was assembled, which was packed in a case, and two devices were mounted on the case: a voltmeter and an ammeter. Also, a familiar electronics engineer soldered a simple controller for him. The principle of the controller is simple, when the batteries are fully charged, the controller connects an additional load that eats up all the excess energy so that the batteries do not recharge.

The first controller soldered by friends did not quite suit me, so a more reliable software controller was soldered.

Installation of a wind generator.

For the wind generator, a powerful frame was made of wooden bars 10 * 5 cm. For reliability, the support bars were dug into the ground by 50 cm, and the whole structure was additionally reinforced with stretch marks that were tied to the corners driven into the ground. This design is very practical and quickly installed, as well as easier to manufacture than welded. Therefore, it was decided to build from wood, and metal is expensive and there is nowhere to turn on welding yet.

Here is a ready-made wind generator. In this photo, the generator drive is direct, but later a multiplier was made to raise the generator speed.

>

>

The generator is driven by a belt, the gear ratio can be changed by replacing the pulleys.

>

Subsequently, the generator was connected to the rotor through a multiplier. In general, the wind generator produces 50 watts in a wind of 7-8 m / s, charging starts in a wind of 5 m / s, although it starts to rotate in a wind of 2-3 m / s, but the speed is too low to charge the battery.

In the future, it is planned to raise the wind generator higher and rework some of the installation components, and it is also possible to manufacture a new larger rotor.
