How to make a wind generator from a car generator?

Wind generators (wind turbines, wind-electrical installations) today are considered one of the cheapest sources of alternative electricity. They are less common than solar panels. However, electric energy produced by the batteries of solar cells is more expensive. So, the windmill in the personal economy is able to be a very efficient and useful source of additional electrical energy. In particular, it can be advantageous if you do not acquire the factory setting, but make it with your own hands from the car generator. The homemade wind generator will be released much cheaper than the factory device.

Device of a wind generator

There are a large number of varieties of wind generators and drawings of their creation. But despite the diversity of species, all structures have the following essential components in their structure:

  • electrical generator;
  • rotor with blades;
  • rechargeable battery;
  • Mast (happens with stretch marks without them);
  • Electrical energy converter (inverter);
  • electronic unit (charge controller);
  • wiring at which electrical energy passes.

In addition, it is required to think in advance the electrical energy control system and distribute the installation circuit.

Instructions for the creation

Training

Before starting work before work should determine which particular device want to make, Since several types of wind generators are practiced, for example, rotary, axial (axial) on magnets and so on.

There are 2 axis accommodation options:

  • Horizontal – the most common, efficiency of this type is twice as much;
  • Vertical – Mounted below, because it has a large mass. Since the wind below is weaker twice, it became, the installation power drops about 8 times. Of the advantages – low noise and ease of operation.

Regardless of the design model, it is necessary to prepare to create a homemade wind generator:

  • automobile generator;
  • voltmeter;
  • Battery charging relay;
  • voltage regulator for variable electrotock;
  • material for the creation of blades;
  • rechargeable battery (helium or acidic);
  • wiring box;
  • Capacity (non-corroding pan or aluminum bucket);
  • 12 V switch;
  • Electric 3-wire cable (cross section of at least 2.5 mm2);
  • old water pipe (with a diameter of at least 15 millimeters, 7 meters long);
  • Charging light bulb;
  • 4 bolts with washers and nuts;
  • Iron Clamps for fixation.

Along with this, you need to have specialized tools for work:

  • grinders with discs;
  • marker;
  • screwdriver;
  • Electrode with drills;
  • Scissors for metal;
  • set of crate keys;
  • gas keys of various numbers;
  • nippers;
  • Roulette.

Rotor

When creating wind-electrical installation It should be taken into account that the rotor of any automotive generator, even from the VAZ, has a winding of electromagnetic excitation. If everything is done with your own, its design can be made easier. You should remove the collector, rewind the stator winding, which will give the opportunity to remake the device into the low-speed. It is advisable to remake the iron rotor.

At the axis of the rotor, not subject to the influence of the magnetic field the nozzle from aluminum is calculated. It is placed on a specialized bandage from a metal pipe.

It should be done with a slight stretch. On the surface of the bandage, there are marked and by superclone put rectangles from magnets made of neodymium. They are glued to the unit with a slight breakdown, which does not allow sticking, observing the alternation of poles. Between these elements are poured with epoxy, which makes it possible to challenge the surface.

Such a wind-electrical installation will produce satisfying the amount of electricity only at a rotational speed of 6000 rpm. To make it productive and at 600 rpm, you need to increase the stator winding 5 times. In parallel, less and the very cross section of the power drive.

The blades of this wind-electrical installation must be large. To lower the magnetic field, it is advisable to move the plates of the stator, align them, after which you mount back.

Wind wheel

The blades are probably the most significant part of the wind-electrical installation. The operation of other installation nodes directly depends on their design. Make them from various materials, sometimes even from the sewer polypropylene tube.

The blades from the pipe are easy to create, it is inexpensive and not exposed to humidity.

The sequence of manufacture of the blade system is as follows.

  1. Required to calculate the length of the blade. The diameter of the pipe must be 1/5 from the cumulative pattern. For example, if the blade is equal to the meter, the pipe with a diameter of 20 centimeters is suitable.
  2. Cut the pipe by logging along the length of 4 segments.
  3. From one segment we make a wing that will serve as a sample for cutting the rest of the blades.
  4. Borrowers at the ends process abrasive.
  5. Blades fix to aluminum disk with welded stripes for fixation.
  6. Then to this disk attach the electric generator.

At the end of the assembly of the blade system Balancing is required. It is fixed on a tripod in a horizontal position. The event is carried out in a closed room. If balancing is performed correctly, the wheel should be motionless. When the blades are spinning independently, then they must be treated until the balance of the balance.

Only with the successful completion of this operation it is necessary to proceed to testing the accuracy of rotation of the blades, they must rotate in the same plane without disrupting the balance. Permissible deviation of 2 millimeters.

2-blade screw on an electric generator without alteration

By and large, if you install a speed 2-blade screw with a diameter of 1-1.2 meters on an electric generator, then such revs are freely achieved at wind speed 7-8 m / s. Consequently, You can make a wind generator and without alteration of the electric generator, it will only function at the wind speed from 7 m / s.

Manufacture of mast

To create a mast suitable Water pipe with a diameter of at least 15 centimeters, approximately 7 meters. If there are facilities within 30 meters from the installed location of the installation, then adjustments are made to the height of the device.

For the productive functioning of the wind-electrical installation, the pocket raise the above barriers of at least 1 meter.

The basis of the mast and stakes for fixing stretch marks are poured concrete. Clamps with bolts boils. For stretch marks used 6 mm cable covered with zinc.

Assembly

To build wind-electrical installation, it is required to make a swivel axis. It can be created from bearings and knees of a 15-centimeter pipe with nuts and threads. You should pour the pipe with epoxy in the body of the bearing, and pour it on a piece of plastic pipe, with a diameter of 50 millimeters. As a result, the movable axis will be.

Wind generator installation sequence:

  • from the profile of 50 × 25 millimeters to make a 60-centimeter beam;
  • fix it on the electric generator beam;
  • fix the tail;
  • do holes for fixing the rotating axis;
  • Install the blades;
  • fix the ready windmill on the mast;
  • Connect a small battery pack;
  • Connect multimeter.

Wind electrical installation is mounted and ready for operation. This wind generator under low weather conditions is able to easily guarantee LED lighting, the operation of the television receiver with a laptop and other little things. But this is exclusively at low weather conditions. With a powerful wind, the production of electricity increases at times.

Service Tips

Windmill, like any mechanism, requires technical control and maintenance.

  1. In special attention to the current collector. The brushes of the electric generator clean, lubricate and regulate once every 2 months.
  2. At the first symptoms of the problem of the vanitary (vibration and wheel-loss) the windmills are lowered to the ground and reveal.
  3. Once every 3 years, steel elements are coated with anticorrosive paint.
  4. Constantly examine fastenings and stretching cables.

When mounting is over, you can connect the equipment and use electricity.
