摘　　要：为充分利用并列转子混合励磁同步发电机的内部空间,本文提出了一种端部铁芯磁极。该磁极放置于永磁转子和电励磁转子直线段铁芯中间,一方面用于电励磁绕组端部的支撑和绑扎固定,另一方面该磁极的C型齿可以产生电励磁调节磁通。针对额定功率为6kW的并列转子无刷混合励磁同步发电机,采用3D有限元法针对端部铁芯磁极的气隙磁场分布进行了分析,并对混合励磁发电机在空载、负载下的输出特性进行了仿真分析;采用2D有限元法对无刷励磁机的性能进行了仿真,得到了直流输出电流和交流励磁电流之间的对应关系。试制了一台原理样机并进行了性能试验,研究结果表明:样机的试验结果与仿真结果较为接近,验证了端部铁芯磁极设计及混合励磁发电机性能仿真的正确性。A kind of end core magnetic pole(ECMP)is proposed to make full use of the internal space of the parallel rotor hybrid excitation synchronous generator(HESG).The ECMP is placed between the permanent magnet rotor and the linear core of the electric excitation rotor.On the one hand,it is used to support and fix the ends of the electric excitation winding,and on the other hand,the electric excitation regulating magnetic flux is generated by the C-type tooth of the ECMP.The 3 D finite element method was used to analyze the air gap magnetic field distribution of the ECMP for the hybrid excitation prototype with rated power of 6 kW,and the output characteristics were simulated and analyzed under no-load and load conditions.The performance of the AC excitation machine was simulated by 2 D finite element method,and the corresponding relationship between DC output current and AC excitation current was obtained.A prototype of HESG was manufactured and its performance test was carried out.The results show that the measured results are close to the simulation results,which verified the correctness of the ECMP design and the HESG simulation.
