A Precision Motion Control of a Circular Platform by using Stepper Motors

Baki Koyuncu; Hakan Koyuncu

A computer interfaced stepper motor control unit is developed to generate motion for a circular platform. Stepper motor unit is connected to LPT parallel port of a computer and user instructions are entered through a system GUI to result circular motion around its motor axis. Control unit is constructed by using 4 power transistors in a driver circuit to drive the stepper motor continuously in 360 degrees with controlled speed and proper right or left rotations. An object oriented high level language is chosen to access the parallel port and send the proper digital pulses to rotate the stepper motor. A graphical user interface, GUI, is also developed to have the user machine interface to control the stepper motors.
