Question
Chapter 33, Problem 1RQ
To determine
Identify the two factors that determine the synchronous speed.
Expert Solution & Answer
Explanation of Solution
Synchronous speed:
The speed at which the magnetic field rotates in a motor is called the synchronous speed. The synchronous speed is given by the formula:
Here, the synchronous speed in RPM is s, the frequency in Hz is f, and the number of stator poles per phase is P.
The two factors that determine the synchronous speed of the motor are given below:
- The number of stator poles per phase.
- The frequency of the applied voltage.
