A switched reluctance (SR) motor has a doubly salient pole structure. It has some merits in comparison with other motors: simple structure, robustness, low cost, and capability for high-speed rotation. However, there are problems of torque ripple and acoustic noise. In addition, the power-to-weight ratio and efficiency need to be improved. Recent advances in power electronics technology allow meticulous current control to reduce the ripple and noise. On the other hand, the core material and motor structure must be further examined to improve the power-to-weight ratio and efficiency. This paper presents a novel SR motor with permanent magnets between the stator poles. The characteristics of the proposed motor are calculated by using a finite element method (FEM) and compared with those of conventional SR motors. The availability of the proposed SR motor is then clarified experimentally.
