Answer / soumen koley
to rotate an induction motor a rotating magnetic field is
needed, which is developed by 3-phase ac supply. but the dc
supply develop a stationary magnetic field in the air gap
which can't able to induce emf in the rotor conductor at
stand still so there will be no torque. so an induction
motor can only start by ac supply.
