If the rotor of an induction motor is made to revolve in a direction opposite to the rotating flux wave, then RMS value of EMF induced in one phase of rotor E is proportional to ____________

If the rotor of an induction motor is made to revolve in a direction opposite to the rotating flux wave, then RMS value of EMF induced in one phase of rotor E is proportional to ____________ Correct Answer 2-s

Relative velocity between rotor winding and rotating flux wave becomes (ω+ωr) = ω+ω(1-s) = ω(2-s) and E = 2πf(2-s)NphrkwΦ.
