Abstract:Research and development wrere done for highspeed twophase switched reluctance motor based on the electric tool drive. Firstly, the rated parameters and main dimensions of the twophase switched reluctance motor were obtained from the performance requirements and size constraints of the singlephase AC series motor which drives the grinding machine. Then this paper uade a study of electromagnetic design. Especially the design of the stepped air gap was optimized to meet the selfstarting capacity and low torque ripple requirements. At the same time it took full advantage of finite element simulation to verify the results of the design. Also, the drive and control system for this motor were developed. And finally both of them were manufactured and the experimental test was conducted. The test results supporting conclusions from analysis were given. Meanwhile it verified the feasibility of this kind of lowcost machine for highspeed driving.
Key words: electric tool；twophase switched reluctance motor；electromagnetic design；drive and control system；finite element analysis
