Concerning the operating characteristics of a synchronous motor, what statement is true?
The synchronous motor initially starts as a synchronous motor and when it approaches synchronous speed, the motor continues to run as a synchronous motor.
The synchronous motor initially starts as an induction motor and when it approaches synchronous speed, the motor then runs as a synchronous motor.
