Synchronous speed formula and pole count needed #2 21672099 05 Aug 2014 19:04 Neil Mula Neil Mula Anonymous Synchronous speed formula and pole count needed Post #2 21672099 05 Aug 2014 19:04 Hi Steve,You can try the ns = (120 x f) / P to calculate the synchronous speed in RPM.The revolution per minute (RPM) denotes the phase difference.You need to identify the number of poles (P) .The formula above is simplified from 1 freq. = 60 cyc,poles assumed by 2 = they are calculated in pairsYou can do the math.or try to check the table I attached.Hope it helps.God Bless.Best,Neil
