摘　　要：文章研究了一种新型双电压输出的复合励磁稀土永磁同步发电机。该发电机的定子采用双绕组结构 ,转子采用永磁体和辅助电励磁相结合的复合励磁结构 ,兼顾了永磁同步发电机和电励磁同步发电机的优点。文章对这种电机结构原理、电磁计算进行了详细分析 ,通过对双绕组电枢反应的d -q轴电磁解耦 ,推导出其电磁计算的数学模型 ,得出各绕组输出电压的数学公式。样机的试验结果与设计结果进行了比较 。A double-voltage hybrid excitation earth rare permanent magnet synchronous generator is designed is this paper. There are two windings in its stator, and its rotor consist of permanent magnet and electrical excitation windings. It takes the advantage of electrically excited and permanent magnet synchronous generator. The structure principle and electromagnetism calculation are detailedly analyzed. A model for electromagnetic calculation and formulas for voltage are obtained by dealing with the d-q axis electromagnetic coupling of the double- winding armature reaction. it is verified to be accurate by the comparison of the results of design and test.
