The principle of a wind turbine is to use wind energy to turn the blades of the wind turbine, then use a speed multiplier to increase the rotation speed to encourage the generator to produce electricity.
The small wind power generation system is very efficient, but it is not only composed of a generator head, but a small system with certain technological content: wind turbine, charger and digital inverter.
A wind turbine consists of a nose, a rotor, a tail and blades. Each part is very important. The blades are used to receive wind energy and convert it into electricity. energy passes through the nose; the tail is used to The blades are always oriented towards the direction of the incoming wind to obtain maximum wind energy; the pivot allows the nose to rotate flexibly to adjust the direction of the tail; the nose rotor is permanent;magnet, and the stator winding cuts the magnetic lines of force to generate electrical energy.
The mechanical connection and power transmission of wind power generation. The horizontal axis wind turbine blades are connected to the universal elastic coupling through the gearbox and its high-speed shaft, and transmit the torque to the transmission shaft of the generator. This coupling should have good vibration damping and absorption characteristics, which means that it can absorb an appropriate amount of radial, axial and some angular deviations, and the coupling can prevent overloading of the mechanical device. The other type is the direct drive type of fan motor where the blades are directly connected to the motor without passing through the gearbox.
