Answer Posted / vikas
simply it will not run because there is no commutator in the ac machines (other than universal motor witch is commutator ac motor). so there is no choice of producing the alternating or rotating flux in the rotor or stator. constant flux will only produce which leads no rotation no back emf so according to lenz law winding may damage (over heat and burn) by drawing excess current from the supply terminals.
