An electric motor is a rotary machine that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or distributed stator winding to generate a magnetic field and a rotating armature or rotor. Some types of these machines can be used as electric motors or generators. It is a machine that converts electrical energy into mechanical energy.

Generally, the working part of a motor makes a rotary motion. This type of motor is called a rotor motor; there are also linear motions called a linear motor. Electric motors can provide a wide range of power, from milliwatts to ten thousand kilowatts. The use and control of the motor is very convenient, with self-starting, acceleration, braking, reversing, and blocking capabilities, which can meet various operating requirements; the motor has a high working efficiency, and there is no smoke, odor, environmental pollution, noise Also smaller.

Because of its series of advantages, it is widely used in various fields such as industrial and agricultural production, transportation, national defense, commerce and household appliances, medical electrical equipment and so on.
