The generator is mainly composed of stator, rotor, end cap, brush, frame and bearing.
The stator consists of a base, a stator core, a wire wrap, and other structural parts that secure these parts.
Rotor consists of rotor core, rotor pole (magnetic choke. Pole pole), slip ring, (also known as copper ring. Collector ring), fan and shaft components.
Through the bearing, the base and the end cap of the generator stator and rotor connection assembled, so that the rotor can rotate in the stator, through the slip ring into a certain exciting current, the rotor into a rotating magnetic field, stator coil to do the movement of magnetic lines , Resulting in the induced potential, through the terminal leads, then connected to the circuit, it produced a current. As the brush and the rotor connected to the open circuit, so that the rotor in a certain direction of rotation, resulting in alternating current so the circuit circuit is the family of alternating current, referred to as alternating current. China's grid output current frequency is 50 Hz.
