How to determine the pole number or synchronous speed of an AC motor from its rated RPM? - Electrical Engineering Stack Exchange
RYB Electrical - Look at the nameplate. It will list the RPMs, or “no load speed” of the motor. From there, you can calculate the number of poles. P=(120∗f)/n , where P =
