Patent ID: 8901798

Claim:
A two-phase switched reluctance machine (TPSRM), comprising: a rotor having a plurality of rotor poles and a characteristic rotor pole pitch, each of the rotor poles having an arced surface; a stator comprising first and second core structures, the first and second core structures each having a main outer segment, each of the core structures having first, second, and third stator poles extending from its main outer segment, and the main outer segments of the first and second core structures disconnected by a medium that is non-conducive to the direct conveyance of flux between the main outer segments; first and second coils respectively disposed around the first and second stator poles of the first core structure, wherein: conveyance of current through the first coil excites a first of the TPSRM's two phases, conveyance of current through the second coil excites a second of the TPSRM's two phases, and the third stator pole of each of the first and second core structures is a common stator pole that conveys flux throughout the excitation of each of the TPSRM's two phases, wherein a length of an arc on a tip of the common stator pole of each of the first and second core structures equals the rotor pole pitch.
