The induced e.m.f. in a synchronous motor working on leading power factor will be_____________?
Correct answer: A. more than the supply voltage
- A. more than the supply voltage
- B. less than the supply voltage
- C. equal to the supply voltage
- D. None of these
Explanation
For a synchronous motor at leading power factor, the reactance-drop phasor causes the internal induced emf to exceed the terminal supply voltage in magnitude. This is the usual overexcited operating condition.
