What is the function of centrifugal switch in the auxiliary winding?

The centrifugal switch in an electric motor, specifically in relation to the auxiliary winding, is designed to disconnect the auxiliary winding from the power supply once the motor reaches a certain speed. This ensures that the auxiliary winding, which aids in starting the motor, is no longer needed during normal operation, preventing overheating and inefficiency. The switch operates based on centrifugal force, typically engaging or disengaging at predetermined RPMs. This mechanism helps optimize the motor's performance and longevity.
