Motors are generally divided into several forms.

Motors are usually classified in the following two ways:

According to the type of working power supply, it can be divided into DC motor and AC motor.

DC engine: an engine that converts DC energy into mechanical energy. When DC motor works, the direction of current will not change, but the magnitude of current may change, thus adjusting the speed of motor. DC motors are often used in automobiles, trams, ships, aviation, railways, toys, electric welding machines, medical equipment, computers and programmable controllers, military equipment and communication equipment.

AC motor: A motor that converts AC electric energy into mechanical energy. When the AC motor works, the direction of the current will change according to the rotation of the motor, and the magnitude of the current will also change, thus adjusting the speed of the motor. Ac motors are often used in household appliances, factory automation production equipment, commercial equipment, wind power generation and other fields.

According to the structure and working principle, it can be divided into DC motor, asynchronous motor and synchronous motor.

In addition, motors can also be classified according to their use, capacity, speed, current type and excitation mode.
