Answer Posted / jishnu
it depends on the winding connection with the armature
1. connected in series
the motor works normally as same
as the DC series motor
2.connected in parallel
the motor will not rotate because the torque
produced in the rotor due to ac is equal and opposite in
magnitude and direction hence resultant torque produced in
rotor is zero
