This paper presents a new design of 30 kw SRD based on fuzzy logic adaptive control, according to the requirement of electric vehicle to the drive system. A new structure is applied on the SRM rotor to minimize the torque fluctuation and noise of the SRM. Based on the experimental results, the SRD system has a low startup current, small torque fluctuation, wide range of speed regulation and high efficiency, all of which are especially suited for the dynamic characteristics of electric vehicle. So it has a broad application prospects.
