The principle of a wind turbine is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the speed of rotation to prompt the generator to generate electricity.
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 power and convert it into electrical energy through the nose; the tail is used to The blades always face the direction of the incoming wind to obtain maximum wind energy; the swivel allows the nose to rotate flexibly to adjust the direction of the tail; the rotor of the nose is a permanent magnet, and the stator winding cuts 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 It should have good damping and vibration absorption characteristics, which means it can absorb an appropriate amount of radial, axial and certain angular deflections, and the coupling can prevent the overload of the mechanical device. The other type is the direct-drive fan motor type where the blades are directly connected to the motor without passing through the gearbox.
