A. The rotating field speed is 1/(p/2) revolutions in one cycle B. f/(p/2) revolutions in f cycles C. f/(p/2) revolutions in one second D. Any of the mentioned
Explanation: f/(p/2) revolutions in one second is also correct because f cycles are completed in one second. ns(rotating field speed in revolutions per second) = 2f/p or Ns = 120f/p r.p.m. 2. The speed at which rotating magnetic field revolves is called
