Since the number of stator poles is constant for a particular machine, the ____ frequency is controlled by adjusting the speed of the rotor.
A) input
B) output
C) operational
D) index

Question

Quizplus · Accepted Answer

The output frequency of an AC motor is directly dependent on the rotational speed of the rotor. Therefore, by adjusting the speed of the rotor, the output frequency can be controlled. The stator poles determine the synchronous speed, but the actual output frequency is dependent on the difference between the synchronous speed and the actual speed of the rotor.
