摘　　要：磁力驱动机构能对力或力矩进行无接触式的传递。一般公式对磁力驱动机构的耦合磁场进行计算的精度不够高,而且不利于其动态性能分析。文章采用ANSYS分析软件对磁转子进行简化分析,详细介绍了从建模到后处理的整个分析过程,精确地得出磁力驱动机构的磁力线分布、磁感应强度的分布情况以及转矩值等,弥补了一般公式误差大的缺陷,可以为进一步研究圆筒式磁力机构提供理论支持。The magnetic driver is a kind of non-contact device that transfer force or the moment. The calculation precision of the general formula is not so high to calculate the coupling field, so as fail to analyse its dynamic feature. This paper adopted the ANSYS software to simplify the analysis of the magnet rotor and expounded the whole analysis process through modeling to postprocessing , then obtained the distribution of flux and magnetic induction intensity of the magnetic driver as well as the torque precisely. It can cover the shortage of the general formula and provide the theory support to further study of cylindrical magnetic driver. [ Ch ,5 fig. 1 tab. 9 ref. ]
