为了解决永磁同步发电机气隙磁场调节困难的问题,研究一种新型混合励磁同步电机,描述它的结构及工作原理。借助电枢反应理论,分析不同励磁电流情况下并列转子混合励磁同步发电机中永磁同步发电机和电励磁同步发电机各自的工作情况,对电机运行过程中存在的3种运行模态(双发电模态、单发电模态和发电–电动模态)进行分析,并探讨了电机3种工作模态的边界线,实验验证了理论分析的正确性。

In order to deal with the difficulty of magnetic field adjustment in permanent magnet synchronous machines, this paper proposed a novel hybrid excitation synchronous machine （HESM） with parallel rotors, and described its basic configuration and the principle. Then, with the analysis of armature reactions, the detailed working performances of permanent magnet synchronous machine （PMSM） and the electro-magnet synchronous machine （EMSM） in HESM were introduced under different exciting current conditions. The operating modes of HESM can be classified into three categories： double-generation mode, single-generation mode and generation-motor mode whose boundaries were deduced. Finally, the experimental results proved the correctness of those analyses.
