摘　　要：为计算筒式实心磁力耦合器(Drum-typeSolidMagneticCoupler,DSMC)的电磁转矩,研究其传动特性,以一台4对极DSMC为研究对象,建立了引入感应电流的等效磁路模型,结合安培环路定律并考虑三维端部效应,推导出耦合器的电磁转矩计算式;运用有限元仿真软件,得到耦合器的磁场分布和感应电流分布及不同输入转速下的机械特性曲线;通过轴向移动导体转子,改变两个转子的相对位置,得到不同啮合长度对电磁转矩的影响规律。最后,搭建试验平台对电磁转矩的理论计算及有限元仿真结果进行试验验证,所得试验结果与分析结果基本一致。该模型为DSMC的设计与优化提供了指导。In order to study the calculation formula of the electromagnetic torque and the transmission characteristics of the drum-type solid magnetic coupler(DSMC),a DSMC with 4 poles was taken as the research object.The magnetic equivalent circuit model introducing the induced current was established,combining with the Ampere's loop law and the 3-D magnetic effect to analyze and calculate the electromagnetic torque.The magnetic field distribution and the induced current distribution of the coupler and the mechanical characteristic curve under different input speeds were obtained by using the finite element simulation software.By moving the conductor rotor axially and changing the relative position of the two rotors,the effects of different meshing lengths on the electromagnetic torque were obtained.Finally,a test platform was built to verify the electromagnetic torque results obtained by the theoretical calculation and the finite element simulation.The experimental results are basically consistent with the above results.The model provides guidance for the design and optimization of the DSMC.
