When the fan has been running for a long time, char has been produced between the rotor and the bearing, which hinders the normal operation of the rotor.
Now the fan motor is smoking, which means the windings are burned out and the motor needs to be replaced to solve the problem. It has nothing to do with the socket at all.
A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a director (tail), a tower, a speed limiting safety mechanism, and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the influence of wind. It converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates driven by the wind rotor shaft to generate electricity. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working medium.
