Stepper Motor Control System
Abstract.At present, a stepper motor drive which has already become a traditional executive device for many electronic devices and systems is a good alternative to microdrives consisting of a high-speed motor with feedback and a mechanical gearbox. The subject of study of this article is a stepper motor. In this paper, the control object (OS) is a two-coordinate transport module based on linear stepper motors (LSD) which is used for the manufacture of high integration chips. For this purpose, a probe that includes a two-coordinate transport module is used. In this article, the technique of controlling the full-step mode was used for a linear stepper motor when designing the system. The stepper motor control system is designed to generate signals on the stepper motor windings and control the rotation speed of its shaft as well as to control the number of pivot steps. In the course of the study, the author developed structural and electric schemes and an algorithm for controlling the system. The developed system is characterized by small overall dimensions, low power consumption, wide functionality. The device uses a modern, widely available, low-cost element base.
