Who knows the way to make a small wind turbine on your own

First of all, you need a generator motor, if you do a miniature wind turbine, then the motor of the four-wheel drive vehicle can be replaced, and then you put the fender board on the head of the front rotor of the motor, which is used to induce the wind, when the wind blows the motor rotor to rotate, the two wire ends at the rear end of the motor can generate electricity, which is the power generation principle of the wind turbine, but this is only to send electricity and has no practicality.

Secondly, if you need a real practical micro wind turbine, you also need to carry out the following steps and prepare some materials, such as a diode, a voltage regulator (voltage regulator circuit board), a battery, etc.

When you prepare these materials, you can first terminate a wire of the generator motor to the diode to prevent the generated power from flowing back to the motor, and then connect it to the voltage regulator (here it needs to be reminded that the voltage regulator power needs to be determined in advance, and needs to meet the parameter requirements of the voltage generated by the motor to prevent the voltage regulator circuit from being burned) and then connect the battery to the voltage regulator (the voltage of the battery should also be within the rated parameters of the voltage regulator) and then it is done, when the wind drives your motor to rotate, The generated power is then processed by the regulator circuit and stored in the battery

It's not something that can be done just by talking, it's a lot of information to be collected. I'm collecting!

It is relatively easy to make your own wind turbines. First of all, a permanent magnet motor (permanent magnet motor, external power supply is the motor, the use of external force to rotate is the generator), permanent magnet motors are in household appliances, such as soybean milk machine, dough machine, etc., as long as the motor is controlled by the control panel, driving the mechanical rotation, most of them are permanent magnet motors. Here's how to make a wind turbine:

1. First, use a piece of wood to fix the generator on the wooden strip, make a U-shaped iron sheet with an iron sheet, and then fix the generator with self-tapping screws.

2. Find a waste electric fan blade and fix the blade on the generator shaft, preferably the fan blade hole is as thick as the diameter of the generator shaft, which can ensure concentricity, which can ensure the balance of the generator.

3. Tie the fixed generator to the outside of the balcony, and the wind blades are facing the direction of the wind (generally there are more east winds), so be sure to pay attention to safety! Securely fastened.

4. Introduce the generator lead into the room, and when the generator encounters the incoming wind, it can rotate and generate electricity.

5. Because the wind direction is not fixed, such as sometimes the east wind, sometimes the west wind, the electricity emitted by the generator, the polarity is not fixed, so in the generator lead-out line, a bridge rectifier must be installed, so that no matter which direction the wind comes, the positive and negative poles emitted by the generator will not change. The circuit diagram of the bridge rectifier is as follows:

2 4 in the figure is two generator lead wires, and 3 1 is the positive and negative output lines. The rectifier diode in the circuit can be used with any model of 1N4001 7.

Materials and tools required: small motor (toy car), small wheel (toy car), six plastic spoons, two cans, wooden boards, iron wire, ballpoint pen refill, hot melt glue gun, utility knife, glue, scissors, small electric drill.

The specific steps are as follows:

1. Use a utility knife to cut two cans, leaving the bottom of each, as shown below.

2. Use a small electric drill to drill holes in the center of the bottom of the can.

3. Glue the two cans together.

4. Use a utility knife to cut plastic spoons, you need six.

5. Glue the cut plastic spoon to the can with a hot melt glue gun.

6. Pay attention to the angle of the spoon, as shown below.

7. Thread a thin wire through the hole in the can.

8. On a small wooden board, glue two small sticks with a hot melt glue gun.

9. Use scissors to cut the ballpoint pen refill into small pieces.

10. Glue the cut ballpoint pen refill to the top of the stick with a hot melt glue gun.

11. Thread the wire through the ballpoint refill and fix it with a hot melt glue gun.

12. Use a hot melt glue gun to fix the small motor and the small wheel together.

13. At the far end of the board, fix a small wooden block with a hot melt glue gun.

14. Fix the small motor on the small wooden block with a hot melt glue gun.

15. Use a vinyl strap to connect the can with the small wheel.

16. The small hydraulic generator is ready, and it can be placed under the faucet for experimentation.

17. If the small bulb on the small motor is on, it means that the production is successful and it can generate electricity.

Engine room, rotor blades, shafts, low-speed shafts, gearboxes, high-speed shafts and their mechanical brakes, generators, yaw devices, electronic controllers, hydraulic systems, cooling elements, towers, anemometers and weather vanes, and rudder are required.

The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the rotation speed through the speed increaser to promote the generator to generate electricity. According to current wind turbine technology, power generation can be started at a breeze speed of about three meters per second (the degree of the breeze).

Wind power is becoming a boom in the world because it has no fuel problems and does not produce radiation or air pollution.

Wind power is popular in countries like Finland, Denmark, etc.; China is also vigorously advocating it in the western region. A small wind power system is very efficient, but it is not only composed of a generator head, but a small system with a certain technological content: wind turbine + charger + digital inverter.

A wind turbine consists of a nose, a rotating body, a tail, and blades.

Each part is important, and the functions of each part are: the blades are used to receive wind power and convert it into electrical energy through the head of the machine; The tail fin keeps the blades facing the direction of the incoming wind for maximum wind energy; The rotating body can make the nose rotate flexibly to achieve the function of adjusting the direction of the tail; The rotor of the machine head is a permanent magnet, and the stator windings cut the magnetic field lines to generate electricity.

Method 1. 1. First of all, buy a generator with a power of 200W and a rated speed of about 400rpm. Then it is the manufacture of blades, here is the use of black ABS pipes, in the country seems to be white is more common, now the sewer pipes are made of this material.

After cutting, it is properly polished and smooth3, find a metal disc, which is used to connect the motor and blades of the generator.

2. Punch holes in the blades and metal disks, and pay attention to the best punching when punching. Find a wheel cover for the wheel, which can prevent the screws from being exposed to the wind and sun, and can also play the role of diversion 6. Make a bracket for the generator, just make a wooden one, and then fix the generator with wire or iron sheet.

3. Make a connecting rod, preferably this place can be equipped with a bearing 8. Make a tower with water pipes, and the bottom of the tower should allow the wires connected to the generator to pass through this hole.

4. Connect the tower and the motor in the hair, fix it with a cable-stayed steel cable, and make a controller and rectifier, so that it can be charged or directly connected to the electrical appliance.

Method two

1. Prepare the required materials, two mineral water bottles, a DC motor, and a pair of scissors 2. Cut the prepared plastic bottle into the shape of a fan blade, that is, cut off part of the bottle.

2. Put the iron nail on the gas stove to burn red, here you should pay careful attention to safety, put the prepared two fan blades together, and burn a hole with the red-hot iron nail.

3. Prepare the motor used and turn a hole in the top of the rotor. The wire is threaded through the hole in the top of the motor rotor to secure the fan blades, or it can be secured with a small screw with a nut.

4. Fix the fan blade on the motor, and fix the motor on the shelf, and install a plastic plate at the tail of the Li Zhao motor as a weather vane.

Homemade wind turbines:

Materials: wires, permanent magnets, rotor shafts, bearings.

Production method: 1. The rotor, the permanent magnet magnet is fixed on the rotor shaft and the number of pole pairs is symmetrical, and the outer circle is formed, which generally affects the voltage is the strength of the magnetic field, the speed of the rotor, and the number of pole pairs.

2. Stator, the wire is wound on the stator core in one direction, the diameter of the wire will affect the power generation current, that is, the power of the generator, and the length and number of turns of the winding affect the voltage.

3. It is best to use iron sheets to superimpose, and the spacing of the stator and rotor affects the magnetic permeability, that is, the voltage and power of the generator will be affected, and it should not exceed millimeters.

The rotor is driven by power.
