摘　　要：介绍了一种用于转速为300 r/min的球形电机的球形转子机构。利用ANSYS Workbench有限元分析软件根据工作状况对转子进行了离心力变形、温度变形、压力变形及3种载荷下的多物理场耦合仿真分析,得出了温度和离心力是实心球形转子产生变形的主要原因及其规律,以及采用静力学与瞬态动力学对同一结构计算结果的差异。不仅证明了此类球形转子在300 r/min转速时的可行性,同时为更高转速的球形电机球形转子的变形仿真提供了重要的参考依据。This article introduce a new kind of sphere rotor structure for sphere motor with rotating speed can reach 300 r/min. Based on the similar working condition of the rotor, the centrifugal force deformation, temperature deformation and pressure deformation of sphere rotor in multi-physical coupling were analyzed with ANSYS Workbench. The result shows that the temperature and centrifugal force is the main course of the rotor deformation and its regular pattern was obtained, the different analysis results in static structural analysis and transient structural analysis was also listed. Analysis results proved that the structure can work with the rotating speed of 300 r/min, it can also be an important reference to the higher rotating speed rotor for sphere motor.
