Rotor Position Detection Techniques of Switched Reluctance Motor without Position Sensor

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.
