Torque developed by a single phase induction motor at starting is_____________?
Correct answer: D. nil
- A. pulsating
- B. uniform
- C. none of the above
- D. nil
Explanation
At standstill, the forward and backward rotating field components produce equal and opposite torques, so their net starting torque is zero. Once given an initial rotation, the motor can continue running as the torques become unequal.
