Q) An induction motor with 1000 r.p.m. speed will have

  • 2 poles
  • 6 poles
  • 4 poles
  • 8 poles
📖 Additional Information

The formula is n = 60 x f /p

Where n = synchronous speed; f = supply frequency & p = pairs of poles per phase.

1000=60*50/P

P=60*50/1000

P=3 Pair of Poles or 6 poles
