Number of Poles given Synchronous Speed in Synchronous Motor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Poles = (Frequency*120)/Synchronous Speed
P = (f*120)/N_s
This formula uses 3 Variables

Variables Used

Number of Poles - Number of Poles is defined as the total number of poles present in any electrical machine.
Frequency - (Measured in Hertz) - Frequency is the rate at which current changes direction per second. It is measured in hertz (Hz).
Synchronous Speed - (Measured in Radian per Second) - Synchronous speed is a definite speed for an alternating-current machine that is dependent on the frequency of the supply circuit.

STEP 1: Convert Input(s) to Base Unit

Frequency: 61 Hertz --> 61 Hertz No Conversion Required
Synchronous Speed: 23300 Revolution per Minute --> 2439.97029416382 Radian per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = (f*120)/N_s --> (61*120)/2439.97029416382

Evaluating ... ...

P = 3.00003652401374

STEP 3: Convert Result to Output's Unit

3.00003652401374 --> No Conversion Required

FINAL ANSWER

3.00003652401374 ≈ 3 <-- Number of Poles
