Associating with the development of power electronic technology and modern control theory, the research on Switched Reluctance Driving (SRD) system becomes the hotspot among the corresponding fields.This paper conducts the research through the control strategy and the design the switch magnetic resistance actuation system. The switch magnetic resistance actuation system have many parameter, and the control mode is flexible, this paper first introduced the switch magnetic resistance electrical machinery on the basic of principle and the structure, and conducted the classified comparison research as the foundation on its control mode.How to improve the torque of the switch magnetic resistance electrical machinery have become the hot spot at present, there upon in above switch magnetic resistance electrical machinery theoretical analysis foundation, therefore we proposed the crosswise magnetic flux to improve the rotate speed, and the torque as principle of he crosswise magnetic machinery. The paper study the rule of the crosswise magnetic machine, the structural design and the optimized. Put forward the methods to improve the torque .Keywords: switched reluctance, crosswise magnetic flux , actuation system, structural design 目 录第 1 章 前言11.1 引言11.2 开关磁阻电机的发展概况11.3 SRD 系统的优点21.4 SRD 研究亟待解决的问题2第 2 章 径向磁通开关磁阻电机的运行原理42.1 SRD 的基本结构42.2 开关磁阻电机传动系统的基本构成42.2.1 开关磁阻电机传动系统的基本构成52.2.2 功率变换器52.2.3 控制器72.3 SRD 的工作原理92.4 开关磁阻电机的线性分析112.4.1 绕组电感112.4.2 绕组磁链122.4.3 绕组电流132.4.4 电磁转矩13第 3 章 横向磁通开关磁阻电机153.1 横向磁通电动机的定义和特征153.2 横向磁通开关磁阻电机的优缺点153.3 横向磁通开关磁阻电机的结构153.4 横向磁通电动机(TFM)的拓扑类型163.5 横向磁通 SR 电动机调速原理183.6 横向磁通电机的磁场分析203.6.1 有限元模型与求解213.6.2 磁场分析与计算213.7 径向磁通电动机和横向磁通电动机拓扑结构的比较223.8 横向磁通开关磁阻电机的应用233.8.1 原动机装置233.8.2 微特电机23第 4 章 横向磁通开关磁阻电机的结构设计及参数优化254.1 横向开关磁阻电机的结构设计
