Answer Posted / joy mohadani
if we apply dc in ac motor is not rotating after few sec(due to inertia of the motor).but after few sec it will stop.we know that in d.c (steady) time period(t) is tense to infinity.so frequency is zero.torque is also depend upon the frequency of the motor.torque is also zero.speed falls to zero.X=2*3.14*f=0.so in motor no reactance part.path is short ckted.after a few sec motor will over heated and damaged
