开关磁阻电机( SRM)的初始位置检测是实现无位置传感器控制的前提条件。在对SRM线性电感模型进行分析的基础上，给出了互感计算式，利用有限元法分析了8/6极SRM互感磁链随转子位置变化的图形。提出了一种无位置传感器SRM转子初始位置检测的新方法，该方法通过向电机定子某一相绕组注入小幅值的激励脉冲，检测相邻两相的互感电压的大小来确定转子的初始位置。通过对8/6极SRM的试验，验证了该方法的可行性和可靠性。

The detection of initial position is the pre-condition to achieve the sensorless control of switched reluctance motor( SRM) . Based on the analysis of linear inductance model of SRM, the mutual inductance formula was given. Using the finite element method, the mutual inductance flux graphs were analyzed, which were changed with the positon of the 8/6 pole SRM rotor. A new initial position detection method of sensorless SRM was given, by which added an excitation pulse with a small value is added to the stator windings, and then the value of the mutual inductance voltage of the two adjacent phase was detected to determine the initial position of the rotor. The feasibility and reliability of the method is proved by experiment of 8/6 pole SRM.
