摘　　要：针对结构参数相同的COMI型和CIMO型磁力耦合器的传动性能进行研究,应用等效磁路法推导磁力耦合器的转矩公式并结合三维修正系数得出磁力耦合器的最终转矩公式,同时推导出磁力耦合器的效率公式。运用有限元软件模拟分析了在同样输入转速和转差率下两种磁力耦合器的传动性能。结果表明:具有同样结构参数的COMI型耦合器相较于CIMO型耦合器具有相同的传动效率,但却可以产生更大的转矩,即传动性能更好。In order to study the transmission performance of the COMI and CIMO type coupler with the same structure parameters,the equivalent magnetic circuit method is used to analyze and derive the torque formula of the coupler,and the final torque expression is acquired by combining the torque formula and three dimensional correction coefficient. Also,the efficiency formula of magnetic coupler is derived. Then,the finite element simulations is used to analyze the transmission performance of the two kinds of couplers when they are under the same input speeds and slips ratio. The results indicate that COMI type coupler has the same transmission efficiency with the CIMO type coupler,but can get bigger torque when they have the same geometrical parameters,which means COMI type coupler has better transmission performance.
