Which of the following statement is true for an AC synchronous motor?
A. It is a constant speed motor.
B. It is a variable speed motor.
C. It is a step angled motor.
D. It is a high reluctance motor.
Answer: A
Share your understanding of this question with the correct explanation.
The correct statement for an AC synchronous motor is:
A. It is a constant speed motor.
AC synchronous motors operate at a fixed synchronous speed determined by the frequency of the power supply and the number of poles in the motor. The rotor of a synchronous motor rotates at the same speed as the rotating magnetic field generated by the stator. Therefore, the AC synchronous motor maintains a constant speed regardless of the load.
Hence, option A is the correct answer.
