Smashing wind generator with their own hands from the automotive generator
The wind generator made from the automotive generator can help in a situation where there is no possibility of connecting to the power line in a private building. Either serve as an auxiliary source of alternative energy. Such a device can be used from undergraduate materials using the developments of folk craftsmen. Photos and video will demonstrate the process of creating a homemade wind installation.
Wind generator design
There is a huge species diversity of wind generators and drawings of their manufacture. But any design includes the following mandatory elements:
- generator;
- blades;
- accumulative battery;
- mast;
- the electronic unit.
Possessing some skills, you can make the wind generator with your own hands
In addition, it is necessary to think in advance the control system and distribution of electricity, draw the installation scheme.
Wind wheel
The blades are perhaps the most important part of the wind generator. From the design will depend on the operation of the rest of the device nodes. Made them from different materials. Even from a plastic sewer pipe. The blade from the pipe is easy to manufacture, it is cheap and not exposed to moisture. The procedure for the manufacture of wind vessels is as follows:
- It is necessary to calculate the length of the blade. The diameter of the pipe should be 1/5 from the total element. For example, if the blade is a meter, then the pipe is suitable with a diameter of 20 cm.
- We cut the pipe with the jigsaw along the 4 parts.
- From one part we make a wing that serves as a template for cutting the subsequent vane.
- Bakery on the edges smoothed abrasive.
- The blades are fixed to an aluminum disk with welded stripes for fastening.
- Next, the generator is screwed to this disc.
Blade for wind wheel
After assembly, the windwell needs balancing. It is fixed on the tripod horizontally. The operation is carried out indoors in the wind closed. In the case of properly conducted balancing, the wheel should not move. If the blades rotate themselves, they need to be treated until the equilibrium of the entire structure is to give.
Only after the successful completion of this procedure should be proceeded to check the accuracy of rotation of the blades, they must spin in one plane without skewing. The error is allowed in 2 mm.

Mast
For the manufacture of the mast, the old plumbing pipe with a diameter of at least 15 cm is suitable, about 7 m long. If there are buildings within 30 m from the intended place of installation, then the height of the design is adjusted towards zoom. For the efficient operation of the wind installation, the pocket is raised above the obstacle at least 1 m.
The base of the mast and pegs for securing stretch marks concrete. Clamps weld with bolts. For stretch marks apply galvanized 6 mm cable.
Council. The collected mast has a considerable weight, with manual installation you will need a counterweight from the pipe with the cargo.
Alteration of generator
For the manufacture of a windmill generator, a generator is suitable from any car. Their designs are similar to each other, and the alteration is reduced to the rewind of the wire of the stator and the manufacture of the rotor on neodymium magnets. In the poles of the rotor, holes for fixing magnets are dried. Install them, alternating poles. The rotor wrapping paper, and emptiness between magnets is poured with epoxy resin.
Automotive generator
In the same way, you can redo the engine from the old washing machine. Only magnets in this case, in order to avoid sticking stick at an angle.
The new winding is rewinding the coil to the tooth of the stator. You can make a mouthpiece, it's how comfortable. The more the number of turns, the more efficient the generator will be. Wind coils in one direction on a three-phase diagram.
The finished generator should be tested and measure the data. If with 300 revolutions generator gives about 30 volts, this is a good result.

Final assembly
The generator frame is welded from the profile pipe. The tail is made of galvanized tin. The rotary axis is a tube with two bearings. The generator is attached to the mast so that the distance from the blade to the mast was at least 25 cm. For safety reasons for the final assembly and mast installation, it is worth choosing a windless day. The blades under the action of a strong wind can be bent and crashing about the mast.
To use batteries for food, which runs from a 220 V network, you will need to install the voltage conversion inverter. Battery capacity is selected individually to the wind generator. This indicator depends on the wind speed on the ground, the power of the connected technique and the frequency of use it.
The device of the wind generator
In order for the battery does not fail from excessive charging, you will need a voltage controller. It can be made independently if you have sufficient knowledge in electronics, or buy ready. There are many controllers for sale for alternative energy mechanisms.
Council. So that the vane does not break with a strong wind, install a simple device - protective vane.
Maintenance of the wind generator
The wind generator, like any other device, needs technical control and maintenance. For uninterrupted windmill work, the following works are periodically carried out.
