The advantages of the cover pole motor include the following aspects:

High stability: due to the existence of the cover pole, the motor can better protect the rotor, thus improving the stability of the motor.

Running mute: the cover of the cover pole motor can prevent electromagnetic noise from radiating outward.

Wide speed range: by controlling the resistance ratio between the main coil and the field coil, the speed of the motor can be adjusted, so it has a wide range of speed control ability.
