A new class of doubly-salient variable reluctance motors which provides greater output torque, higher efficiency, quicker response, and a simple structure in comparison to conventional reluctance motors by utilizing a specific stator/rotor pole arrangement and by altering the magnetic structure of the motor by using permanent magnets to provide a linearly increasing flux linkage over the entire area of pole overlap.
