软硬件协同设计的步进电机细分技术的研究

Research into Subdivided Technology of Stepping Motor Based on Hardware-Software Co-design

摘要:

本文以满足两相混合式步进电机的运行特性为出发点,设计了驱动控制系统的硬件和软件控制系统。驱动控制系统主要分为控制部分、驱动器部分、系统供电电源模块等。以单片机STC89C51为微处理器控制核心,实现对步进电机的运转方向和速度快慢的执行控制。驱动硬件电路核心部分采用高精度细分驱动芯片THB6128实现对步进电机的精细驱动,测试结果较理想。实际应用的结果表明,该系统稳定可靠,应用简单可行。

Abstract:

To meet the operator characteristic of the two-phase hybrid stepping motor, the software and hardware of the driving control system was designed. The driving control system is consists of the control part, driving part and the power supply system etc. It utilized the STC89C51 as the core to control the reverse moves and speed of the motor. Driving part adopted high subdive driver THB6128 chip. Experimental results show that the system is feasible.
