摘　　要：随着永磁材料的发展,永磁式发电机也得到了日益广泛的应用,尤其是在需要简单可靠的直流电源的场合.本文建立了永磁同步发电机和二极管整流桥构成的永磁无刷直流发电机的数学模型, 采用数字仿真的方法分析了这种电机的静态和动态工作特性,分析表明永磁式无刷直流发电机具有较硬的外特性和快速的动态响应过程,在分析含该类电机的系统特性时可以采用其稳态工作特性.The continuous advances being made inthe permanent magnet materials, have led to them beingconsidered for use in generators, specially in the condi-tions where robust and reliable DC source are. needed.Mathematic model of permanent magnet brushless DCgenerators (PMG with a diode rectifier) has been estab-lished in this paper, static state and dynamic state charac-teristics have been investigated by the method of mathe-matic simulation. The research results in that the PM DCgenerators have stiil output characteristics and fast dy-namic responds. The steady state characteristics of PMbrushless DC generator could be used in analyzing thesystems which consist with this machine.
