| 摘 要： | 复合磁路三相定子混合励磁双凸极直流发电机的励磁线包和永磁体在与转轴正交的同一剖面上,电励磁磁通和永磁磁通复用电机磁路具有励磁功率小、励磁调节范围可按要求设计、可以实现单输出或双路输出的特点。文章介绍了该型电机的典型结构,使用时步有限元法分析其工作模态,基于场分析结果提取电感特性,计算比较空载特性、外特性,仿真计算了双路输出的开环调整率。分析结果表明,该电机既能作为独立供电系统的无刷直流发电机,又能并网发电,特别适于航空和其他野外作业场合高速发电机用,并实现起动/发电一体化,应用前景广泛。

| Abstract: | The field windings and permanent magnets of compound flux-path three-phase stator hybrid excited doubly salient DC generator are on the same cross-section orthogonal to the shaft,where flux excited by field windings and permanent magnets multiplexes the core paths.This machine has small excitation power,can regulate its field in a designing range,and outputs in one channel or double channels.This paper introduces the typical topologies,analyses the operating modes with Transient FEM,and extracts the inducta... |
