The motors are divided into direct current motors and alternating current motors according to different power supplies, most of the motors in the power system are alternating current motors, and can be synchronous motors or asynchronous motors (the rotating speed of a stator magnetic field of the motor is different from the rotating speed of a rotor and keeps synchronous speed). The motor mainly comprises a stator and a rotor, and the direction of the forced movement of the electrified conducting wire in a magnetic field is related to the current direction and the direction of a magnetic induction line (magnetic field direction). The working principle of the motor is that the magnetic field exerts force on current to enable the motor to rotate.
