Rotational speed of traditional wind turbine

Motor. A wind turbine consists of a nose, a rotor, a tail and blades. Each part is very important, and the function of each part is as follows: the blade is used to receive wind power and convert it into electric energy through the nose; The tail wing makes the blades always face the direction of the incoming wind to obtain the maximum wind energy; The rotor can make the nose rotate flexibly and realize the function of adjusting the direction of the tail; The rotor of the handpiece is a permanent magnet, and the stator winding cuts the magnetic field lines to generate electric energy.

2. Tower

3. Wind vane. The rated speed of blades is generally 18~30 rpm, and the speed can be increased to about 2000 rpm through the speed-increasing gear at the back to ensure the normal operation of the generator. If the blade speed is too fast, according to the speed change ratio, the speed after speed change is too fast, which is easy to burn out the motor. Therefore, when the wind becomes stronger, the blades will adjust the windward angle to control the speed or brake.

4. Inverter power supply. Because the air volume is unstable, the fan outputs 13 ~ 25V alternating current, which must be rectified by the charger before charging the battery.

5. battery. It is special and cannot be stored directly with the battery of electric vehicle.
