What will happen if we give AC supply to DC motor?

Answer Posted / velpula.nagarjuna

in dc motor when we give ac supply to the armature then the motor is not run. because the direct flux produce from the permanent magnets, but from the armature winding the alternating flux is produced.that means the flux is rotated continuously.the the polarity of the armature flux continuously changes... the the aiding of the flux is not possible..with out aiding of the flux no torque will be produce..no torque means no rotations...that means the hunting will be processed........
