摘要 直线驱动系统由于机械结构简单而获得广泛应用。本文提出一种基于磁场平衡式霍尔电流传感器的永磁直线同步电机的电流检测系统及其实现方案。分析了电流检测系统的基本原理、电流信号的处理以及电流的过流保护的功能,实验结果验证了电流检测系统的有效性。 The linear motor system is widely used because of the simple structure, This paper presents a feasible scheme of the current detection system based on the magnetic balanced Hall current sensor. The system basic principle, the current signal processing and over-current protector are analyzed respectively. The validity Of the current detection system is confirmed by the experimental results.
