The speed of a shaded-pole induction motor is determined by the same factors that determine the synchronous speed of other induction motors-____ and number of stator poles.
A) direction of rotation
B) size
C) frequency
D) age

Question

Quizplus · Accepted Answer

The speed of an induction motor is directly proportional to the frequency of the power supply, as per the relationship given by the formula: 
Synchronous speed = (120 * frequency) / number of stator poles. Therefore, the frequency of the power supply is one of the factors that determine the speed of a shaded-pole induction motor.
