[0002] An electric motor is a rotating electrical machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or a distributed stator winding to generate a magnetic field and a rotating armature or rotor. Under the action of the rotating magnetic field of the stator winding, current flows through the effective side of the stator winding and is rotated by the magnetic field. According to the principle of motor reversibility, if the motor does not undergo any changes in its structure, the motor can be used as a motor or a generator.
