Answer / sunny deol

dc series motor because with the change in ac cycle the direction of magnetic field of both field winding and armature winding changes and the net effect becomes zero,so motor continues to rotate in the same direction.

Answer / saurabh jain

dc series motor because direction of torque changes wid d change in direction of current, so overall direction remains d same.
