• How to determine the pole number of an induction motor

Nov 15, 2014 The formula is n = 60 x f / p where n = synchronous speed; f = supply frequency & p = pairs of poles per phase. The actual running speed is the synchronous speed minus the slip speed. For a 50 Hz three phase supply: 2 poles or 1 pair of poles = 3,000 RPM (minus the slip speed = about 2,750 RPM or 6 -7% n) 4 poles or 2 pairs of poles = 1,500 RPM
