Which of the following statements regarding single-phase induction motors correct?
Correct answer: D. It is not self-starting
- A. It requires only one winding
- B. It can rotate in one direction only
- C. It is self-starting
- D. It is not self-starting
Explanation
A single-phase induction motor has a pulsating rather than rotating starting field, so its starting torque is zero. It must be given an auxiliary winding or another starting method before it can run.
