The mechanical displacement of the rotor with respect to the stator, in polyphase multipolar synchronous motors running at full load, is of the order of_____________?
Correct answer: C. five degrees
- A. zero degree
- B. two degrees
- C. five degrees
- D. ten degrees
Explanation
The rotor load angle in a normally loaded synchronous motor is small because the rotor remains nearly aligned with the rotating stator field. A value of about five degrees is the closest typical order among the choices.
