Answer : Centrifugal switch disconnects the auxiliary winding of the motor at about 70 to 80 percent of synchronous speed.

Answer : In a single phase motor the centrifugal switch disconnects auxiliary winding of the motor.

Answer : If the centrifugal switch of a two-value capacitor motor using two capacitors fails to open then Electrolytic capacitor will, in all probability, suffer break down.

Answer : In a capacitor start motor, the phase displacement between starting and running winding can be nearly 90°.

Answer : The starting winding of a single-phase motor is placed in stator.
