摘　　要：转矩波动是永磁同步力矩电机的固有缺陷,主要是由齿槽力引起的。针对加工过程中由齿槽转矩引起的转矩波动影响加工精度的问题,根据传统齿槽转矩优化方法及齿槽转矩计算方式,分析了力矩电机齿槽转矩主要的影响因素,对比分析了电机参数优化调节和内外双转子力矩电机异构优化这两种减小齿槽转矩的方法,验证了内外双转子异构力矩电机具有转矩波动更低的优势。The torque ripple is the inherent defect of permanent magnet synchronous motor,which is caused by cogging force.In order to solve the problem of torque fluctuations that affect the machining precision,this paper analyzed the main factors that influence the motor cogging torque by the traditional cogging torque optimization method and cogging torque calculation method,by comparing two methods reducing cogging torque,which are the traditional motor parameters optimization regulation and inner and outer rotor heterogeneous motor design,the advantage of inside and outside dual rotor heterogeneous torque motor is verified,which has lower torque ripple.
