Abstract

The authors proposed a novel segment type switched reluctance motor (SRM) and showed the torque ripple could be reduced by increasing the phase number. This paper presents the relationship between the exciting current and the number of phases and segment cores. Transient analysis by the finite element method is carried out when the number of phases is 4 to 6. For torque ripple reduction the best number of phases is 4. It is also confirmed that the average torque is increased by making the number of phases increase.
