摘要 目前,无刷直流电动机无位置传感器研究正受到越来越广泛的关注,而反电动势过零检测法是转子位置检测方法中技术最成熟应用最广泛的转子位置检测方法之一。但是这种方法也存在各种缺点。本文分析了反电动势过零检测法产生转子位置误差的原因,对传统的反电动势过零检测法做了改进,并且提出了相应的补偿方法。 In comparison with the use of position sensors, the applicaion of sensorless Brushless DC Motor is more reliable and economiacal. At present, and the principle of zero-crossing detection of the back-EMF is one of the most successful technology used for detection of the rotor-position. This paper analyzes the rotor-position error caused by the zerocrossing detection and a compensation method is proposed.
