摘　　要：为进一步提升永磁力矩电机的转矩性能并加强表贴式永磁体的贴磁稳定性,讨论了一种新型燕尾形隔磁装置结构。首先,搭建电机初始模型,并对新型燕尾形隔磁装置结构进行参数化设计。其次,根据电机的等效磁路模型和电磁转矩产生原理,建立了考虑燕尾形隔磁装置结构的平均转矩和转矩脉动数学模型。然后,借助ANSYS Maxwell有限元仿真工具,以平均转矩为优化目标,对不同隔磁装置槽口宽、隔磁装置内圆半径及位置进行了仿真分析并讨论其变化规律。最后,将优化后电机与初始电机的平均转矩和转矩脉动进行了对比分析,结果表明,最优隔磁装置结构参数方案提高了37.2 N·m的平均转矩且削弱了0.04%的转矩脉动。In order to further improve the torque performance of permanent magnet torque motors and enhance the magnetic stability of sur-face-mounted permanent magnets,a new dovetail-shaped magnetic isolation device(DMID)structure was discussed.First,the initial model of motor was constructed,and the structure of DMID was designed parametrically.Second,based on the equivalent magnetic circuit model of motor and the principle of electromagnetic torque generation,a mathematical model of average torque and torque ripple consider-ing the DMID structure was established.Then,with the help of finite element simulation tool ANSYS Maxwell,taking the average torque as the optimization target,different slot widths,inner circle radiuses and positions of DMID were simulated and analyzed,and their chan-ging rules were discussed.Finally,the average torque and torque ripple of the optimized motor and the initial motor were compared and analyzed.The results show that when the optimal structure parameters of DMID are selected,the average torque is increased by 37.2 N·m,and the torque ripple is weakened by 0.04%.
