Analysis of a Novel Indirect Rotor-Position Sensor for Switched Reluctance Motor

提出了一种新型的基于测试线圈技术的无位置传感器方案.这种方案是通过测量导通相测试线圈的电感来获得实时转子位置的.文中对此进行了理论分析和实验验证,并成功地开发完成了一台无位置传感器开关磁阻电机原理样机.

A new kind of indirect rotor-position sensor which is based on test winding tech-nique for switched reluctance motor(SRM) is proposed. The scheme is applied to get the real-time rotor-position by measuring the inductance of the test winding of the conducting phase.Detailed theoretical analysis and experimental results are also presented. A prototype using in-direct rotor-position sensor is developed successfully.
