摘　　要：利用磁路和有限元的计算方法,探讨了4种径向结构永磁转子作为永磁同步发电机时电机性能的差别,研究了产生这些区别的原因,分析了各自漏磁的情况。指出转子采用4种不同的径向结构时,电机的电抗、电压变化率、短路电流、短路比、静态和动态稳定度、漏磁等均有变化,从外特性、电压波形正弦畸变率、运行稳定性、漏磁等方面比较了4种径向结构永磁电机的性能。Using the computing methods of magnetic circuit and finite element, this paper discusses the different performance of four types of radial structure permanent magnet rotors serving as permanent magnet synchronous generator（PMSG）, studies the reasons that cause these differences, analyses the magnetic flux leakage of each type, points out that reactance, voltage rate of change, short circuit current, stabilization of static state and dynamic state, and magnetic flux leakage are all different with the four types of rotors, and makes comparative study of the performance of the four types of radial structure permanent magnet generators in the aspects of external characteristics, voltage sinusoidal waveform distortion rate, running stability, magnetic flux leakage and so on.
