C)revolutions per minute
D)trips per minute

Question

Quizplus · Accepted Answer

The speed of the rotor is directly related to the number of poles established in the stator. The fewer the number of poles, the greater the speed in revolutions per minute (RPM). The speed of the rotor is directly proportional to the frequency of the power supply and inversely proportional to the number of poles established in the stator. Therefore, fewer poles will result in a higher speed in revolutions per minute (RPM) of the rotor.
