| Research Abstract |
An SR motor, as a reliable, low-cost motor without rare earth materials, its application to In-wheel Direct-Drive car, which is an ultimate electric vehicle, is expected. However, large torque ripple and low efficiency are serious drawbacks. In the study, a new control method to reduce torque ripple and drive at high efficiency was proposed. And the low-cost and high-efficiency control circuit for multi-drives was developed.
