无UVW位置信号检测的永磁同步电机传动系统研究

Investigation of PMSM Drive System without Detecting the UVW's Position

本文研究了无 UVW 位置信号检测的永磁同步电机控制方法。电机启动过程分析表明转子初始位置确定是问题的关键。本文提出了两种不同负载类型传动系统的电机转子初始位置的确定方法,并在一类实际系统中得到实现。结果表明本方法是可行的。

Without detecting the UVW＇s position, a control method of permanent magnet synchronous motor was investigated in this paper. The analysis of the starting process of PMSM indicates that determining the initial rotor position is the key. For two drive systems having different load, in this paper, two methods to determine the initial rotor position were proposed and realized in some kind of actual system. The results show that the methods are feasible.
