摘　　要：为得到鼠笼转子异步磁力联轴器内部磁场的直观分布情况,首先给出了空载磁场理论分析,其次运用ANSYS软件对影响该磁力联轴器气隙磁场的主要因素:磁极数、永磁体厚度、内转子槽数、槽宽和槽深进行了模拟分析.结果表明当磁极对数为14极,永磁体厚度为8mm,槽数为24槽,槽宽为8mm,槽深为18mm,在安装允许的范围内气隙长度为最小时磁力联轴器的气隙磁密最大.鼠笼转子异步磁力联轴器的有限元分析方法为该类联轴器的结构优化设计提供了一种新思路.In order to obtain the visual distribution of internal magnetic field in squirrel cage rotor of asynchronous magnetic coupling, theoretical analysis of no-load magnetic field was given. Influencing factors in air gap magnetic field of this coupling including magnetic pole number, permanent magnet thickness, length of air gap, slot numbers of inner rotor, slot width and slot depth were analyzed by ANSYS. The results show that the air gap flux density reaches the maximum in the erection range when the magnetic coupling is 14 poles, the thickness of permanent magnets is 8 mm, slot number is 24, the width of slots is 8 mm, and the depth of slots is 18 ram. The finite element analysis of squirrel cage rotor of asynchronous magnetic coupling provides a new way to optimize the structure of this magnetic coupling.
