开关磁阻电动机（switchedreluctancedrivers，SRD）的非直接位置传感器技术是开关磁阻研究领域的热门课题之一。本文详细地介绍了一种新型的开关磁阻电机非直接位置传感器方案，这种方案通过测量测试线圈的电感来获得实时转子位置信息，并使用了线圈反串技术和串联谐振技术来消除开关磁阻电机内部电磁场对于测试电路的干扰。详细地阐述了方案的工作机理，并给出了如何使用该方案进行开关磁阻电机的正常启动和运行控制的具体实施方法。

Indirect rotor-position detecting technology is one of the most popular projects in SRD (switched reluctance drivers) research area. A novel SRD indirect rotor-positiondetecting scheme which get the real time rotor-position by measuring the inductance of the test windings is presented.Opposite-connect sensing coils technique and series resonance technique are introduced to get rid of the disturbance caused by interior electromagnetic field of SRD. The principle of the scheme is described in detail. And in addtion,some specific approach on how to realize proper control of SRD's starting and running is supplied.
