In a single phase motor the centrifugal switch____________?
Correct answer: A. disconnects auxiliary winding of the motor
- A. disconnects auxiliary winding of the motor
- B. disconnects main winding of the motor
- C. reconnects the main winding the motor
- D. reconnects the auxiliary winding of the motor
Explanation
The auxiliary winding is needed mainly for starting, so the centrifugal switch disconnects it after the motor reaches a suitable speed. The main winding remains connected during normal operation.
