Whether there is any change if we give ac supply to a dc motor?
Nah, it'll be fine. Go for it.
If it is a series wound DC motor with brushes it will run on AC voltage, but the voltage has to be the same. For instance if the AC voltage is 120 then the DC voltage needs to be 120. If it is wound any other way the motor will short out and burn up and maybe trip a breaker or cause a fire.
Any change? what do you mean? Certainly the motor won't work, it will just sit there and vibrate. And possibly burn out, depending on the voltage.
