To determine

The synchronous speed of the six pole motor operated with an applied voltage of 20 hertz.

Expert Solution & Answer
Check Mark

Explanation of Solution

Consider the formula for the synchronous speed is,

    Ns=120fP

Then, the synchronous speed is calculated as,

    Ns=120206=400rpm

Thus, the synchronous speed is 400rpm.
