步进电机的精细控制

Fine control of a step motor

本文介绍一种应用MCS-51系列单片机和电流变换电路,实现对步进电机的精细控制,使运行步距角由三相单、双六拍式的15°减少至3.75°甚至更小,大大提高了运转的控制精度和平滑性。

This paper introduces the fine control of a step motor by means of MCS-51 series monolithic computers and a current converting circuit which reduce the three-phase single, double and six-beat step elongation from 15° to 3.75° or below 3.75°. The control accuracy and operating stability of the motor are thus greatly improved.
