Synchronous motor always runs at______________?
Correct answer: A. the synchronous speed
- A. the synchronous speed
- B. less than synchronous speed
- C. more than synchronous speed
- D. none of the above
Explanation
A synchronous motor locks its rotor to the rotating stator field, so its steady-state speed is exactly synchronous speed. Unlike an induction motor, it does not require slip to produce torque.
