| 摘 要： | 针对于小功率少相数SR电机的特性和控制方式,在无位置传感器的情况下采用了简化磁链法来估算转子位置;并根据两相SR电机的上一相断电与下一相通电时刻的不同步性,做了相应的处理,提出了一种简便的判断下一相导通时刻的方法;最后用软件实现了两相SR电机的无位置传感器时的位置检测。

| Abstract: | Based on the control mode and character of two phase SRM,in this paper,the simplified flux method was used to estimate rotor position without position sensor.Because the time cutting off one phase s electricity and the time that the current is switched on for a another phase isn t synchronization,a method for judging the time that the current is switched on for a another phase is proposed.At the end,using the software,this paper implement the estimation of rotor position without position sensor. |
