How to Determine Speed for an Ac Induction Motor | 2000-09 ...

Sep 30, 2000· The mathematical formula to remember in helping make this calculation is the number of cycles (Hz) times 60 (for seconds in a minute) times two (for the positive and negative pulses in the cycle) divided by the number of poles. Therefore, for a 60-Hz system, the formula would be: 60 x 60 x 2 = 7,200 no-load rpm ÷ number of poles.
