Outline of Final Research Achievements

Switched reluctance motors (SRMs) are advantageous in cost because they do not use permanent magnet which inevitably requires rear earth metals. SRMs are, however, quite difficult to be controlled because their input current is not proportional to generation torque. The study has searched preferable controls for SRMs limiting their use in EV and HEV. As a result, field weakening control, maximum torque control, maximum efficiency control, and so on have been established. Appropriate change of the controls has provided much better drive performance over all operating range.
