摘要

摘要: 磁齿轮啮合型电机是一种具有新颖电磁结构的永磁驱动元件，其具有转矩密度高、低速转矩大等优点。在分析所研究磁齿轮啮合型电机工作原理和齿槽转矩表达式后，得出了影响磁齿轮啮合型电机齿槽转矩的几个因素，利用有限元的方法建立了电机二维模型，对影响电机齿槽转矩及其波动的各种因素进行了仿真分析，得到了齿槽转矩及波动与电机结构尺寸和永磁体材料的变化关系。

Abstract: The magnetic-geared motor is a permanent magnetic drive element with novel electromagnetic structure, which has the advantages of high torque density, high torque at low speed, etc. The work principle and the cogging torque expression of the magnetic-geared motor are analyzed first in this paper. Then several factors which influence the cogging torque of the motor are obtained. A two-dimensional model of the motor is established by the finite element method and each factor is simulated separately. At last, the change relationship between cogging torque and the size of components or the materials of permanent magnets is displayed.
