1, DC generator
A DC generator is a machine that converts mechanical energy into DC electrical energy. It is mainly used as DC motor, electrolysis, electroplating, electric smelting, charging and AC generator excitation power required.
2, DC motor
A rotating device that converts DC electrical energy into mechanical energy. The stator of the motor provides a magnetic field, and the DC power source supplies current to the windings of the rotor. The commutator keeps the torque generated by the rotor current and the magnetic field in the same direction.
3, brushless DC motor
Brushless DC motors are the development of microprocessor technology in recent years and the application of high-frequency switching, low-power new power electronic devices, as well as the optimization of control methods and the emergence of low-cost, high-magnetic-capacity permanent magnet materials. A new type of DC motor developed.
