If load (or torque) angle of a 4-pole synchronous motor is 6° electrical, its value in mechanical degrees is__________?
Correct answer: B. 3
- A. 2
- B. 3
- C. 4
- D. 6
Explanation
Electrical angle equals pole pairs multiplied by mechanical angle. A four-pole motor has two pole pairs, so its mechanical load angle is 6°/2 = 3°.
