Characteristics of a novel segment type SRM with 2-step slide rotor

The authors proposed a high power and low vibration novel segment type switched reluctance motor (SRM), but it had a problem of large torque ripple. We propose in this paper a novel segment type SRM with 2-step slide or skew rotor to reduce the torque ripple. We produce the experimental machine and confirm the characteristics. The average torque decreases slightly in comparison with the non slide one, but the torque ripple is decreased well. We confirm also that the vibration is decreased too.
