Question

Quizplus · Accepted Answer

The speed of rotation of the magnetic field in a three-phase motor is called the synchronous speed. This speed is determined by the frequency of the AC power supply and the number of poles in the motor, and it is the speed at which the magnetic field rotates.

In a Three-Phase Motor, the Speed of Rotation of the Magnetic
