what happens when a DC supply is given to AC motor?
Answer Posted / pranav priyadarshi
actually when dc supply is given to ac machine there will generate const field due to which rotor won't rotate, and also stator draws large current due to which i^2*r losses is more and hence more heat is generate ,due to which machine may burnt out......
