What will happen if supply to three phase motor is given
wiyhout inerting rotor in it?How much current it will draw?
Answer Posted / rajendran
With out the presence of the rotor there will not be any
back emf (In opposition to the supply voltage)....
So the stator winding will draw very high currents from the
mains and the fuses will blow immediately....
