Switched reluctance machines with segmental rotors are investigated, building on previous work which has produced high torque prototypes. The paper presents a machine topology, which permits the use of short pitched windings placed around a single-tooth. This concept maintains the torque capability of a previous design, but uses much less copper volume. The theoretical basis for the machine configuration is developed and then the results for a working prototype machine are shown, illustrating static torque and flux linkage profiles. Results are presented for the machine operating as a drive, indicating the viability of the concept.
