摘　　要：应用表面磁荷间的作用力,导出了同步径向型永磁联轴器传动扭矩的计算公式。考虑了轭铁的影响。扭矩公式表示成有限个单元函数的求和形式,易于程序化。利用导出的公式可迅速进行联轴器的几何尺寸与材料性能等参数分析。计算结果与其它算法比较偏差较小,满足工程设计需要。By calculating the force between the magnetic charges on the face of magnet poles, a formula is derivated for computing the torque of synchronous radial couplings. The torque formula is expressed as a sum of finite elementary functions and involves the effect of iron yokes, which is easy to be programmed .The formula enables rapid parametric analysis of coupling performance relative to geometric dimensions and material properties. Better agreement is achieved between the computering results of the formula and others, meeting requirement of engineering design.
