What is the reason behind using a centrifugal switch in a single-phase induction motor?

• A. To cut-off the starting winding at an appropriate instant
• B. To improve the starting performance of the motor
• C. To protect the motor from overloading
• D. To out in the capacitor during running conditions

Answer: (A)

The centrifugal switch is used to disconnect the starting winding of the motor once the motor approaches its normal operating speed i.e 50% – 70% speed.
