传统脉振高频电压信号注入法在估计永磁同步电机(Permanent Magnet Synchronons Motor,简称PMSM)转子位置时,因无法辨识转子N/S极而存在位置估算可能相反的问题.利用电机磁场的饱和效应.提出了一种新型转子位置辨识方法,通过分析包含转子位置误差信息的二次高频电流分量,对转子永磁体磁极极性进行判别.结合传统方法.准确辨识出转子位置.对一台凸极式PMSM进行了转子位置估计实验,验证了该方法的有效性.

The estimation result of the rotor position for permanent magnet synchronous motor(PMSM)maybe revelse with traditional pulsing high-frequency voltage signal injection method,since this method cannot recognize N/S rotor polamity.A new method is proposed to identify rotor position based on motor saturation effect.N/S polarity is distinguished by analyzing the second high-frequency current component with rotor position error information,and then rotor position can be easily obtained.The experiment is implemented on a PMSM with salient pole.The experimental results verify the proposed ap-proach,and it achieves the valid rotor position polarity identification.
