摘　　要：提出了一种具有不等定子齿宽的磁通反向永磁振镜电动机,通过敏感度分析,选取大定子齿宽、小定子齿宽、转子齿宽和槽肩宽4个参数作为影响因素,以转矩密度、转矩变化率、齿槽转矩和电感为优化目标,采用田口法进行正交试验分析,获得不同因素水平下的目标响应,并结合灰色关联法,将多目标优化转化为单目标优化问题,实现了电动机的最优设计.通过电动机性能的对比分析,验证了所设计的电动机的优越性和优化设计方法的有效性.A flux reverse permanent magnet galvanometer motor with unequal widths of stator tooth widths was proposed.Based on sensitivity analysis,four parameters,including the widths of large stator teeth,small stator teeth,rotor teeth and slot shoulder,were selected as the influencing factors.Moreover,the torque density,the torque change rate,the cogging torque and the inductance were taken as the optimization objectives.The orthogonal test analysis was performed using the Taguchi method to obtain the target response under different factor levels.Then the optimal design of the motor was realized by introducing the grey correlation method,by which the multi-objective optimization was transformed into a single-objective optimization.By the comparative analysis of motor performance,the superiority of the proposed motor and the effectiveness of the optimization design method were verified.
