Classification of motors

Classification of motors Motor classification:

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

1) According to their structure and working principle, DC motors can be divided into brushless DC motors and brushless DC motors.

Brushless DC motors can be divided into permanent magnet DC motors and electromagnetic DC motors.

Electromagnetic DC motors are divided into series excited DC motors, parallel excited DC motors, separately excited DC motors, and compound excited DC motors.

Permanent magnet DC motors are divided into rare earth permanent magnet DC motors, ferrite permanent magnet DC motors, and aluminum nickel cobalt permanent magnet DC motors.

2) AC motors can also be divided into single-phase motors and three-phase motors.

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

1) Synchronous motors can be divided into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors.

2) Asynchronous motors can be divided into: electric motors and AC commutator motors.

Electric 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 motors, AC/DC dual-purpose motors, and repulsive motors.

3. According to the starting and operating modes, it can be divided into capacitor started single-phase asynchronous motors, capacitor started single-phase asynchronous motors, capacitor started single-phase asynchronous motors, and phase separated single-phase asynchronous motors.

4. Divided into drive motor and control motor.

1) Drive motors can be divided into: motors for electric tools (including drilling, polishing, polishing, slotting, cutting, reaming, etc.), household appliances (including washing machines, fans, refrigerators, air conditioners, recorders, video recorders), vacuum cleaners, cameras, hair dryers, electric shavers, and other general small mechanical equipment (including various small machine tools, small machinery, medical instruments, electronic instruments, etc.).

2) Control motors are divided into stepper motors and servo motors.

According to the structure of the rotor, it can be divided into cage type motors (formerly known as squirrel cage asynchronous motors) and wound rotor motors (formerly known as wound asynchronous motors).

6. According to the operating speed, it can be divided into high-speed motors, low-speed motors, constant speed motors, and speed regulating motors. Low speed electric motors are divided into gear motors, electromagnetic motors, torque motors, and claw pole synchronous motors.

Adjustable speed motors can be divided into stepper constant speed motors, continuously variable speed motors, stepper continuously variable speed motors, and continuously variable speed motors. It can also be divided into electromagnetic speed control motors, DC speed control motors, PWM frequency conversion speed control motors, and switched reluctance speed control motors.
