what will happen if dc motor given ac supply
Answer Posted / kaushik
In case of dc motors ,if provided with ac supply will run because in every halfcycle the polarity of field and armature winding will change simultaneously so that torque will be in same direction (regardless wether it is series or shunt motor) but the field winding will be hotter as they are not laminated (as they are designed for working with dc) so excess heat will produce due to eddy current.
