According to different operating speeds of motors, they can be divided into high-speed motors, low-speed motors, constant-speed motors, and speed-regulating motors.
Low-speed motors are further classified into gear reduction motors, electromagnetic reduction motors, torque motors, and claw-pole synchronous motors.
The speed regulating motor can be divided into a stepped constant speed motor, a stepless constant speed motor, a stepped variable speed motor and
In addition to the stepless variable speed motor, it can also be divided into an electromagnetic speed regulating motor, a DC speed regulating motor, a PWM variable frequency speed regulating motor and a switched reluctance speed regulating motor.
The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field.
