本文重点对步进电机细分驱动原理进行了分析,通过对细分电流波形的合理选择,以及以AT89C51单片机作为核心的选择,经过对步进电机驱动芯片L297/298的结合,实现了步进电机的斩波恒流细分驱动控制系统的设计。
In this paper, the principle of subdivision drive of stepping motor is analyzed. Through the reasonable choice of the subdivision current waveform and the choice of AT89C51 singlechip as the core, the stepping motor driver chip L297 / 298 is combined to realize stepper Design of a Chopper and Constant Current Subdivision Drive Control System for a Motor.
