Alternating Current (A.C.) Motors are modified in such a way as to provide zero to full nameplate torque, by inserting magnetic rods into elongate control-rod-receptive channelways in the stator. By moving the rods in and out of their respective channelways the magnetic path of the stator flux will change. With the rods all the way out of the stator full nameplate torque is achieved. As the rods are inserted deeper into the stator, the output torque of the rotor will decrease proportionally to a minimum value.
