摘　　要：基于磁场能量法,给出磁场调制式永磁齿轮(Field Modulated Permanent Magnetic Gear,FMPMG)的齿槽转矩数理模型,进而得出与齿槽转矩相关的结构参数;提出了不同结构参数的优化修型方法,并借助有限元仿真(FEM)验证其有效性;通过仿真结果比对获得FMPMG的最优修型方法,有效减小齿槽转矩,并使FMPMG的动力学特性最优.Based on magnetic energy method,a mathematical approach is proposed to analyze the cogging torque of field modulated permanent magnetic gear. Correlation structure parameters are figured out according to the mathematical model,and relevant design techniques are put forward by using FEM examples. A comparison among different design techniques is made to figure out the best design technique for weakening the cogging torque.
