摘　　要：转子磁分路径向结构混合励磁同步电机利用磁分路结构可以方便地调节电机的气隙磁场。本文描述了电机的结构和原理,研究了该电机的空载特性,针对空载电动势调节范围较小的问题,探讨了减小电机导磁体间的漏磁、提高气隙磁通密度的方法,并讨论了永磁部分长度、电励磁部分长度对电机空载特性的影响。仿真和实验结果表明:磁分路径向结构混合励磁同步发电机适宜短而粗的结构,其轴向长度的变化对电机的空载特性影响很大。With the help of the magnetic shunting, the air-gap magnetic field of the radial structure hybrid excitation synchronous machine（HESM）is convinent regulated. The structure and priniple of HESM were described, no-load characteristic is researched. Aim to solve the question of the no-load voltage has small range, the paper discusses method the decrease leak magnetic between magnetizer and increase air gap flux, and talked about the lengths of parmanent magnetic parts and an electric magnetic part impact on no-load running characteristic of HESM.The simulation and experimental result show the machine is suitable for short and wide structure, and magnetic shunt radial structure HESM＇s axis direction length influences the no load running characteristic of machine＇s.
