The generator is the mechanical energy into electrical energy equipment, installed in the power plant, the generator according to the use of power is divided into DC generator and alternator, the power system of the generator is mostly AC motor, but also synchronous motor (motor rotor and stator rotation to maintain synchronous speed). The generator is mainly composed of stator, rotor and end cover. Brush, frame, bearing and other components. The stator consists of a frame, a stator core, a wire wrap winding, and other structural parts fixing these parts. The rotor consists of a rotor core and a rotor pole (with a magnetic choke). Pole winding), slip ring, (also known as copper ring. Collector ring), fan and rotating shaft components.
