开关磁阻电机设计研究

An Investigation on Switched Reluctance Motor Design

本文分析了开关磁阻电机的结构和运行特性,提出了第二临界运行点与第二临界转速的新概念;给出了考虑开关磁阻电动机运行时饱和性、开关性和可控性等特点的转矩计算;阐述了满足既有恒转矩区又有恒功率区的宽调速范围运行的开关磁阻电机的设计思想和方法。文中还进行了样机设计计算与试验结果比较。

The inherent specific features of the switched reluctance motor (SEM) are discussed and the concept of second critical operating point and second critical speed is proposed. The design method for meeting the demand on a wide range of speed control in constant torque and constant power regions is given. Test results obtained on a sample machine show that the design method presented is feasible.
