摘　　要：转子位置检测是开关磁阻电机调速系统的重要环节,直接位置检测技术能够提供稳定的转子位置信号,但需要增加附加的机械结构,从而限制了开关磁阻电机的应用范围。目前,无位置传感器检测技术是开关磁阻电机研究领域的热点之一。全面介绍了国内外开关磁阻电机无位置传感器检测技术的研究现状,详细阐述了每一典型检测方法的原理,对其优缺点及适用范围进行了详细讨论与客观评述,并展望了其发展趋势。对新型无位置传感器检测技术的研究具有重要的参考价值。Rotor position-detection is essential to the timing system of SRM. Direct rotor position sensors provide stable rotor position signals. However, the use of direct sensors leads to additional mechanical structures, which greatly limits the application SRM. Today, indirect rotor-position detecting technology is one of the most popular projects in SRM research area. In this paper, the status of researching on sensorless rotor position detection is introduced firstly, then the principle of the representative schemes are particularly described, the merits, flaws and application fields of these schemes are also discussed impersonally, the future trends of the sensorless detection techniques for SRM are given at last.
