What will happen if we give DC supply to AC motor?

Answer Posted / periyasamy.n

The a supply there is no resistance to limit the field current
, in ac only impedance will be presented it doesn't reduce the current value so the windings are damaged. Also ac will not produce the flux , so the motor does not run
