WebHow to Calculate Motor RPM. To calculate RPM for an AC induction motor you multiply the frequency in Hertz (Hz) by 60 — for the number of seconds in a minute — by two for the negative and positive pulses in a cycle. You then divide by the number of poles the motor has: (Hz x 60 x 2) / number of poles = no-load RPM. Web22 okt. 2008 · Re: Fastest Rotation Of An Electric Motor. 11/18/2007 9:06 PM.
