What is an electric motor

A motor is a device that converts electrical energy into mechanical energy. It uses the energized coil (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric rotational torque.

Motors are divided into DC motors and AC motors according to different power sources. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the stator magnetic field speed of the motor and the rotor rotation speed do not maintain a synchronous speed).
The motor is mainly composed of a stator and a rotor, and the direction of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic field line (magnetic field direction). The working principle of the motor is that the force of the magnetic field on the current causes the motor to rotate.
The DC motor adopts an octagonal full lamination structure and series winding, which is suitable for automatic control technology that requires forward and reverse rotation. It can also be made with series excitation windings according to user needs.
