Q.The mmf produced by the current of a 3-phase induction motor

  • ARotates ate the speed of rotor in the air gap
  • BIs standstill with respect to stator mmf
  • CRotates at slip speed with respect to stator mmf
  • DRotates at synchronous speed with respect to rotor
Correct Answer : (B)

Is standstill with respect to stator mmf

Hints :

The mmf produced by the current of a 3-phase induction motor is standstill with respect to stator mmf.
