When the voltage applied to a synchronous motor is increased, which of the following will reduce?
Correct answer: D. None of the above
- A. Stator flux
- B. Pull in torque
- C. Both A. and (b)
- D. None of the above
Explanation
Increasing the applied voltage increases stator flux and also increases pull-in torque, which is approximately proportional to the square of the applied voltage. Therefore, neither quantity reduces.
