<p>Electrically-energized salient stator poles (40 to 54) of a variable reluctance motor terminate in stator teeth that oppose the rotor (10). Permanent magnets (110, 120) located between adjacent stator teeth and magnetized transverse to the stator to rotor gap enhance the motor torque relative to the applied excitation in ampere-turns. Permanent magnets on the rotor of variable reluctance motors are avoided by reversing the magnetization of the permanent magnets (110, 120) from pole to pole and energizing the pole windings to oppose the magnets in four phases 1 1 0 0, 0 1 1 0, 0 0 1 1, 1 0 0 1 during successive steps. In one embodiment, a linear motor utilizes the system by replacing the rotor with a linear actuator.</p> |
