An over excited synchronous motor is used for____________?
Correct answer: D. power factor corrections
- A. fluctuating loads
- B. variable speed loads
- C. low torque loads
- D. power factor corrections
Explanation
An overexcited synchronous motor draws leading current, which supplies leading reactive power and improves a lagging system power factor. It is therefore commonly used for power-factor correction, not primarily for speed or load variation.
