摘要：本文提出了一种双交错混合励磁电机，该电机采用交流调磁方式，可以简单、灵活地调节电机气隙磁场、改变线圈感应电动势，具有双向对称调磁能力。本文分析了该电机的结构特点和工作原理，结合该新型电机的磁场分布，建立了交直轴等效磁路模型，计算了各段磁路上的磁阻，进而求得电枢绕组中感应的磁通。同时，采用三维有限元分析法对电机进行仿真，得到不同调磁状态下的电枢反电动势。将两种方法的计算结果进行对比，二者基本一致，验证了所提出模型的有效性。

Abstract: In this paper, a Dual Consequent Hybrid Excitation Synchronous (DCHES) Machine was presented. The DCHES machine adopts AC excitation mode, which equips the machine with a symmetric bidirectional flux control capability. Its structure and working principles were analyzed in this paper. According to the magnetic field distribution of DCHES machine, the dand qaxis equivalent magnetic circuit models were established, then the reluctance of each part of magnetic circuit and the flux coupled with the armature winding were deduced. At the same time, the threedimensional finite element analysis method was used to calculate the airgap flux and the backEMF under different excitation levels. The results coming from two different methods were consistent with each other, which verified the presented model in this paper.
