Application note

Stepper motor driving

By Thomas Hopkins

Introduction

Dedicated integrated circuits have dramatically simplified stepper motor driving. To apply

these ICs, designers need little specific knowledge of motor driving techniques, but an

understanding of the basics helps in finding the best solution. This note explains the basics

of stepper motor driving and describes the drive techniques used today.
