what happens when a DC supply is given to AC motor?
Answer Posted / nd.palanivel
No rotating magnetic field is generated and hence the motor
will not rotate, instead a break is applied on the rotor for
a sort period. Depends on the magnitude of the DC supply and
the DC resistance of the coil, heat will be generated on the
coil. Coil will burn if the supply is applied continuously.
