Not only can a synchronous motor drive a load with greater efficiency than an induction motor, a fringe benefit of the synchronous motor is the ability for power factor correction. What statement is true?

Correct Answer: Option C — If the overall plant has a unity power factor, the synchronous motor is normally-excited.

Under USCG National Maritime Center examination standards, the accepted correct answer is: If the overall plant has a unity power factor, the synchronous motor is normally-excited..
