The range hoods, electric fans, ventilation fans, hair dryers, etc. in households use AC motors; DC motors for electric shavers, electric bicycles, toy racing cars, etc.

A DC motor is a motor that converts DC electrical energy into mechanical energy. Due to its excellent speed regulation performance, it has been widely used in electric traction. DC motors are divided into three types based on excitation methods: permanent magnet, separate excitation, and self excitation, among which self excitation is further divided into three types: parallel excitation, series excitation, and compound excitation.

An AC motor is a device that converts the electrical energy of alternating current into mechanical energy. An AC motor mainly consists of an electromagnetic winding or a distributed stator winding used to generate a magnetic field, and a rotating armature or rotor. An electric motor is made by utilizing the phenomenon of a energized coil rotating under force in a magnetic field. AC motors are divided into two types: synchronous AC motors and induction motors.
