基于嵌入式系统的步进电机驱动设计

为了提高步进电机的稳定性，改善启动时出现的震动，论文介绍了一种基于嵌入式系统的步进电机驱动设计方案。系统中用FPGA来控制DA等器件来实现细分驱动技术，达到了1／64细分，使电机运行稳定；用ARM＋Linux编写电机驱动来实现升频启动，降低了启动时的震动；用QT编写的人机界面，可以控制电机正反转、运行速度、转动角度等，操作简易。该设计方案满足要求，已经得到了应用。

Design of Stepping Motor Driver Based on Embeded Systems

This paper present a design of Stepping motor driver based on Embeded Systems for enhancing the stability of the Stepping Motor and reducing the start-up shake.This system lets FPGA control these devices such as DA to achieve Subdivision technology,which can reach 1/64 subdivision and is stable;it lets ARM+Linux to program the motor driver to achieve Ascending frequency startup,which reduces the start-up shake greatly;the GUI programed using QT can easily control the inversion,speed and angle of the motor.T...
