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

1) DC motor can be divided according to structure and working principle: brushless DC motor and brushed DC motor.

Brushed DC motors can be divided into: permanent magnet DC motors and electromagnetic DC motors.

Electromagnetic DC motor division: series excitation DC motor, parallel excitation DC motor, other excitation DC motor and compound excitation DC motor.

Permanent magnet DC motor division: rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and aluminum nickel cobalt permanent magnet DC motor.

2) Among them, THE AC motor can also be divided into: single-phase motor and three-phase motor.
2,.according to the structure and working principle can be divided: can be divided into DC motor, asynchronous motor, synchronous motor.

1) Synchronous motor can be divided into: permanent magnet synchronous motor, magnetoresistive synchronous motor and hysteresis synchronous motor.

2) Asynchronous motor can be divided into induction motor and AC commutator motor.

Induction motors can be divided into three-phase asynchronous motors, single-phase asynchronous motors and shaded-pole asynchronous motors.

AC commutator motors can be divided into: single-phase series excitation motors, AC-DC dual-purpose motors and push-repulsion motors.

3. According to the starting and operating mode, it can be divided: capacitor starting single-phase asynchronous motor, capacitive running single-phase asynchronous motor, capacitive starting single-phase asynchronous motor and split-phase single-phase asynchronous motor.
4. According to the use, it can be divided: drive motor and control motor.

1) The drive motor can be divided into: electric tools (including drilling, polishing, polishing, slotting, cutting, reaming and other tools) with motors, home appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, VIDEO DISC players, vacuum cleaners, cameras, hair dryers, electric shavers, etc.) with motors and other general small mechanical equipment (including various small machine tools, small machinery, medical equipment, electronic instruments, etc.) with motors.

2) The control motor is divided into stepper motors and servo motors.

5. According to the structure of the rotor, it can be divided: cage induction motor (the old standard is called squirrel cage asynchronous motor) and winding rotor induction motor (the old standard is called winding type asynchronous motor).
