磁力离合器(MC)安装过程中存在一定的轴系偏差。针对两转子之间存在角向和径向偏差的情况，基于偏差模型和三维有限元方法，分析和研究MC的磁场分布、涡流分布、轴向磁拉力、转矩等基本电磁特性。随着径向偏差距离的增加，气隙磁场和导体盘涡流分布整体沿径向偏差，MC转矩呈下降趋势。随着角向偏差的增加，气隙磁场和涡流密度呈非对称分布，且出现明显的不平衡轴向磁拉力，但是输出转矩先下降然后平稳上升。

There is a certain shafting deviation during the installation of magnetic clutch (MC). In view of the angular and radial deviation between the two rotors, the magnetic field distribution, eddy current distribution, axial magnetic pull, torque and other basic electromagnetic characteristics of the MC are analyzed and studied by deviation model and three-dimensional finite element method. With the increase of the radial deviation distance, the air gap magnetic field and eddy current distribution of conductor disk are shifted along the radial direction, and the torque of MC decreases gradually. With the increase of the angular deviation, the air gap magnetic field and eddy current density are asymmetrically distributed, and it shows obvious unbalanced axial magnetic pull, but the output torque drops first and then rises steadily.
