How does a windmill turn?

The rotation of paper wind turbines is now used in wind power generation. The principle is the same: Wind turbines are electrical equipment that converts wind energy into mechanical work. Mechanical work causes the rotor to rotate and ultimately produces reciprocating output. current. It is generally composed of wind turbines, generators (including devices), steering deflectors (tails), towers, speed-limiting safety mechanisms and energy storage devices. The operating principle of a wind turbine is relatively simple. The wind rotor rotates under the influence of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft to generate. electricity. Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a generator using thermal energy that uses the sun as aheat source and the atmosphere as the working fluid. According to the characteristics of fixed torque wind turbines and variable pitch, constant frequency and variable speed wind turbines, the motors currently installed in China are generally divided into asynchronous, synchronous, horizontal axis and vertical axis wind turbines.
