A motor is a rotary electric machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or distributed stator winding used to generate magnetic field and a rotating armature or rotor. Under the action of the rotating magnetic field of the stator winding, the current in the armature squirrel cage aluminum frame passes through and is subject to the action of the magnetic field to make it rotate.

It is a machine that converts electrical energy into mechanical energy. Usually, the working part of the motor rotates, which is called rotor motor; There are also linear motion, called linear motor.
