A Novel Unidirectional Switched Reluctance Machine 931390

A novel, two-phase, switched reluctance machine concept is presented. Pole side shaping assures that the machine can develop motoring torque from any static position. Pole face shaping is introduced to control the nature of flux linkages as a function of position, allowing reduction in position-dependent torque ripple over conventional switched reluctance machines. Since the machine has 50% of the magnetic circuit active at any point in time, whereas the three-phase switched reluctance machine has 33% of the magnetic circuit instantaneously active, the new design shows increased power density over the common three-phase machine.
