Electronic Drive System for Four Stepper Motors

Abstract

This article describes the progress of an ongoing project to design an electronic drive system for four stepper motors. The product is part of the Maestro Phantom, an electromechanical system replicating the human torso's breathing movements. Four stepper motors are used to track the movement of the model. The main task of this article is to drive a stepper motor using a PIC microcontroller and LabView. This article describes the hardware and software used to drive stepper motors. The stepper motors are driven by a PIC18F4520 microcontroller mounted on a microchip development board. Additionally, the working principle of stepper motors is explained and the advantages and disadvantages of stepper motors are discussed. This article explains how to drive a stepper motor in different directions and speeds and how to count the number of steps and revolutions.
