To determine

The two factors that determine the synchronous speed of the motor.

Expert Solution & Answer
Check Mark

Explanation of Solution

The speed of the consequent pole of the motor is changed by the change in the stator pole number.

The two factor that determine the speed of the AC motor is frequency of the applied voltage and the number of stator poles per phase.

Thus, the synchronous speed is changed by the frequency change and the number of stator poles.
