Interfacing Stepper Motor with PIC Microcontroller

Introduction A Stepper Motor is a brushless, synchronous DC electric motor, which divides the full rotation into a number of equal steps. It finds great application in field of microcontrollers such as robotics. Please refer the article Stepper Motor or Step Motor for detailed information about working of stepper motor, types and modes of operation. Unipolar Motor is the most popular stepper motor among ele ...

Unipolar 4-Phase Stepper Motor Controller

This project is a 4-phase unipolar stepper motor controller. Description Unipolar 4-Phase Stepper Motor Controller Board will help you control a Stepper Motor or 4 individual Solenoids. This circuit consisting of transistors that serve as current amplifier and also diode to prevent damaging back EMF, circuit uses Darlington transistors to provide high current capacity to unipolar stepper motor. Just provide ...

Simple manual control of stepper motors without a PIC or PC

This instructable will show you how to control stepper motors (Unipolar OR Bipolar) manually with a knob, without the use of a PIC or PC, so no programming is needed.  The position of the knob determines the position of the motor shaft, which will stay in that position until the knob is turned again.  The unipolar and bipolar circuits are different, but each requires only 1 chip. Step 1: Here's what you'll ...

Stepper Motor Controller using PIC16C84

For another project I started I needed to control the motion of a stepper motor. A stepper motor is used when precision control of movement is needed. With each movement of the motor, the drive shaft steps a precise amount of distance (usually a few degrees with each turn). You can often salavage steppers from old printers or disk drive. I found mine at an electronics surplus store. The key to driving a ste ...
