1. classification by type of working power supply:

It can be divided into DC motor and AC motor.

1.1 DC motor can be divided into brushless DC motor and brush DC motor according to structure and working principle.

1.1.1 brush DC motor can be divided into permanent magnet DC motor and electromagnetic DC motor.

1.1.1.1 electromagnetic DC motor is divided into series excited DC motor, parallel excited DC motor, separately excited DC motor and compound excited DC motor. V:swfb520

1.1.1.2 classification of permanent magnet DC motor: rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and aluminum nickel cobalt permanent magnet DC motor.

1.1 AC motor can also be divided into single-phase motor and three-phase motor.

2. according to structure and working principle:

It can be divided into DC motor, asynchronous motor and synchronous motor.

2.1 synchronous motor can be divided into permanent magnet synchronous motor, reluctance synchronous motor and hysteresis synchronous motor.

2.2 asynchronous motor can be divided into induction motor and AC commutator motor.

2.2.1 induction motor can be divided into three-phase asynchronous motor, single-phase asynchronous motor, shaded pole asynchronous motor, etc.

2.2.2 AC commutator motor can be divided into single-phase series excitation motor, AC / DC dual-purpose motor and repulsion motor.

3. according to the starting and operation modes:

Capacitor started single-phase asynchronous motor, capacitor operated single-phase asynchronous motor, capacitor started single-phase asynchronous motor and split phase single-phase asynchronous motor.

4. by use:

Drive motor and control motor.

4.1 motor for driving: motor for electric tools (including drilling, polishing, polishing, slotting, cutting, reaming and other tools) Motors for household appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVD players, vacuum cleaners, cameras, hair dryers, electric shavers, etc.) and motors for other general small mechanical equipment (including various small machine tools, small machinery, medical appliances, electronic instruments, etc.).

4.2 control motors are divided into stepping motors and servo motors.

5. according to the structure of rotor:
