Physics · Induction Motors
Crawling typically causes a three-phase induction motor to operate at a stable speed that is:
- 1slightly below the synchronous speed under full load
- 2equal to the synchronous speed
- 3double the synchronous speed
- 4a small fraction (e.g., 1/7 or 1/13) of the synchronous speed due to harmonics✓
Correct answer
a small fraction (e.g., 1/7 or 1/13) of the synchronous speed due to harmonics
