May 06, 2008 Good Answers: 29. # 1. Re: Speed control for capacitor start AC motors. 05/04/2008 5:19 PM. Cap-start motors usually have a centrifugal switch that drops out the start capacitor at about 2/3 - 3/4 of full speed. If you try to reduce the fan speed below the centrifugal switch's cut-in speed, you will get the effects complained of.

What happens if the centrifugal switch does not open?

May 19, 2020 A centrifugal switch is an electric switch that operates using the centrifugal force created from a rotating shaft, most commonly that of an electric motor or gasoline engine. Here, the switch is used to disconnect the starting winding of the motor once the motor approaches its normal operating speed.

Most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost always replaced.
