Project 7.19—Stepper Motor Control Projects—Simple Unipolar Motor Drive
This project is about using stepper motors in microcontroller-based systems. This is an introductory project where a stepper motor is driven from a microcontroller.
Before going into the details of the project, it is worthwhile to look at the theory and operation of stepper motors briefly.
Stepper motors are commonly used in printers, disk drives, position control systems, and many more systems where precision position control is required. Stepper motors come in a variety of sizes, shapes, strengths, and precision. There are two basic types of stepper motors: unipolar and bipolar.
Unipolar Stepper Motors
Unipolar stepper motors have two identical and independent coils with center ...
