摘　　要：详细分析了电磁耦合无级变速系统的工作原理及其调磁原理,在此基础上,利用有限元法对其进行二维有限单元和三维有限单元的分析,研究了电磁耦合无级变速器的磁场的相关特性及调磁对气隙磁场的影响。根据调磁对气隙磁场的影响,计算得出调磁对该系统效率的影响,研究结果为电磁耦合无级变速系统的控制策略及控制系统开发提供了基础。The working principle and adjusting the magnetic field principle of the system of electric --magnetic continuously variable transmission（EMCVT） were analyzed in detail herein. By the 2D FEM and 3D FEM, the magnetic field on EMCVT and the effect of adjusting magnetic field on the air --gap magnetic field was studied. And according to the effect of adjusting magnetic field on the air-- gap magnetic field, the efficiency of EMCVT was also studied, so as to prepare for the development of the control strategy and control system.
