How to Calculate the RPM of a Motor

For a 60 Hz system with four poles the calculations to determine RPM would be Hz x 60 x 2 / number of poles = no load RPM 60 x 60 x 2 / 4 7 200 / 4 = 1 800 RPM The amount of slip varies slightly based on the motor s design A reasonable full load speed for a 60 Hz four pole motor would be 1 725 RPM.
