Design of a kind of stepping motor controlled by 51 chip

In this article, appliying the SCM, stepper motor driver CMOS, character type LCD and keyboard array, the stepper motor control system which is consisted of stepper motor controller and driver are constructed. AT89S51 SCM is adopted to realize the controlling of rotate speed for two related stepper motors. The impulse signal from the stepper motor is changed into four corresponding impulses by the impulse distributor and the four decomposed impulses drive the stepper motor＇s roUing by the driver circuit＇s enlarged power. The device can reduce effectively the cycle time of system development area and cost.
