摘　　要：设计了微特电机主轴的磁流体密封结构。采用ANSYS软件中的MULTIPHYSICS,对磁流体密封结构进行建模、划分网格、加载、求解,分析出极齿宽度、极齿高度、齿槽宽度、密封间隙对密封性能的影响,得到了磁流体密封装置的最佳密封结构参数,大大提高了微特电机的使用寿命。The magnetic fluid seal structure of micro special electrical motor was designed. By modeling, meshing the geometry, applying loads and solving on the magnetic fluid seal structure with the MULTIPHYSICS product in the ANSYS software, the influence of tooth width, height, tooth slot width, seal gap on the seal performances was analyzed, the optimal magnetic fluid seal structure parameters were got, the service life of micro special electrical motor shaft was improved.
