摘　　要：建立了永磁同步发电机和二极管整流器构成的永磁无刷直流发电机的数学模型。采用数字仿真方法分析了该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电源系统的特性时，可以采用其稳态工作特性。Continuous advances made in the permanent magnet materials have led to considerthem for use in generators,especially under the conditions where robust and reliable DC sourcesare needed. Mathematical model of permanent magnet brushless DC generators (PMBLDCGs)has been established. Characteristics of static and dynamic states have been investigatedthrough mathematical simulation. Research results show that the PMBLDCGs have stiff outputcharacteristics and fast dynamic responses. Steady state characteristics of PMBLDCG can beused in the analysis of the systems conlsisting of this machine.
