摘　　要：在系统介绍轴向磁齿轮复合电机基本工作原理的基础上,提出了一种具有聚磁式转子的轴向磁齿轮复合电机。采用有限元分析方法对复合电机的电磁性能进行了三维数值仿真分析,验证了电机结构的合理性,并详细分析了聚磁式转子结构参数对电机输出转矩与轴向磁拉力的影响,得出转子参数对转子两侧圆周和轴向磁拉力的影响相似,为后续的试验研究提供了理论参考。The principles of magnetic field modulation and axial magnetic gear composite motors are firstly systematically described.Based on thus,an axial magnetic gear composite motor with a spoke-type rotor structure is proposed.And the finite element analysis method is adopted to carry out three-dimensional numerical simulation analysis of the electromagnetic performance of the composite motor,which verifies the reasonableness of the structure of the motor.The influence of each parameter of the spoke-type rotor on the output torque and axial magnetic pulling force of the motor is further analyzed,and it is concluded that the influence of the rotor parameters on the circumferential and axial magnetic pulling force of the two sides of the rotor is similar,which provides a theoretical basis for subsequent experimental research.
