It all depends upon whether the motor is a series motor or
shunt , if the motor is series then it would be running but
quite unsatisfactorily with increased sparking during
commutation and heating. however a shunt motor wont run
because of the high inductance of its field windings ( due
to greater no. of turns ) it will oppose the change in the
magnitude and direction of current which is th case with
ac .
