In induction motors, the length of air gap in kept as small as mechanically possible is order to have____________?
Correct answer: B. high power factor
- A. low power factor
- B. high power factor
- C. high over load capacity
- D. any of the above
Explanation
A small air gap reduces the reluctance of the magnetic circuit and therefore lowers the magnetizing current. The resulting stator current has a better power factor, making high power factor the intended answer.
