【摘要】 在SRD的设计中,SRM初始位置的检测是间接位置检测首先必须解决的问题。在对SRM电感模型和连续两相电磁特性分析的基础上,提出了一种无位置传感器SRM启动前转子初始位置检测方法,该方法通过向电机定子相绕组注入激励脉冲,并检测相邻两相的互感电压来确定转子初始位置,使其正确启动。通过对8/6极四相开关磁阻电机的实验,验证了该方法的可行性。更多还原

【Abstract】 In the design of SRD,the initial position of SRM must first be resolved for indirect position examination.A method which detects the rotor initial position and decides the relevant starting phase was proposed,based on the analysis of the inductance model of SRM.This method,which by pouring the test pulse into the stator phase of SRM and examining the neighboring two mutual inductance voltage,determines the rotor initial position and makes SRM start correctly.It is proved by theoretical analysis and also demonstrated by experiment of SRM(8/6).更多还原
