Abstract

The project is titled as “Development of an embedded controller for stepper motors application”. In this project, the embedded controller developed is based on Rabbit microprocessor and its core module model RCM 2000. This project is to design and develop variable speed controlled stepper motor drive using rabbit microprocessor. The control method implemented in this project is variable speed control method. Instead of using assembly language to compile the variable speed; this controller will use Dynamic C programming language to develop the algorithm. The goal of the project is to design and develop a laboratory scale functioning prototype in order to demonstrate the interfacing between the variable speed algorithm in Rabbit microprocessor and the stepper motor speed drive. The Rabbit microprocessor based variable speed controller is able to generate pulse wave signal. The desired pulse wave signal generated is an input signal for stepper motor speed drive in order to control the speed of stepper motor. The major hardware implementation in this project is Rabbit microprocessor. Rabbit microprocessor is chosen due to its specification features of high speed, easydesign hardware system and low power consumption. Besides, variable speed driver also need to be developed to operate with two units of stepper motors or more.
