Microcontroller Based Stepper Motor Drive for an Elevator System

Abstract

The thesis addresses a microcontroller based unipolar stepper motor drive used for an elevator system. The elevator system developed can move up and down, along with the feature of floor display indicator incorporated in it. The opening and closing of elevator doors are indicated with green and red LED’s respectively. The elevator system is divided into four floors of equal heights, so that the stepper motor took equal number of steps while moving from one floor to another. The elevator system is operated using micro switches, the control program is developed in C language and Kiel compiler is used to converts this control program into executable file or say in a HEX code.
