1. Classified by power supply type: DC motors and AC motors.
DC motors:
Classified by structure and working principle: brushless DC motors and brushed DC motors.
They can also be divided into permanent magnet DC motors and electromagnetic DC motors.
Permanent magnet DC motors are further classified by material into rare earth, ferrite, and alnico permanent magnet DC motors.
Electromagnetic DC motors are further classified by excitation method into series excitation, shunt excitation, separate excitation, and compound excitation DC motors.
AC motors can be divided into: single-phase motors and three-phase motors.
2. Classified by structure and working principle: DC motors, asynchronous motors, and synchronous motors.
The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field.
The rotor speed of a synchronous motor is independent of the load size and always remains at the synchronous speed.
3. Classified by use, there are drive motors and control motors.
4. Classified by operating speed, there are high-speed motors, low-speed motors, constant-speed motors, and speed-control motors.
Low-speed motors are further divided into gear reduction motors, electromagnetic reduction motors, torque motors, and claw-pole synchronous motors, etc.
