Design And Construction Of A PC-Based Stepper Motor Controller

ABSTRACT

A pair of H-bridges with a software program written in ‘C++’ is used to control the bipolar stepper motor with a step resolution of 18 degree per pulse.

The PC based stepper motor controller is a combination of driver and switching circuits. The driver is the actual circuit that drives the stepper motor and the switching circuit decides how the motor should be driven. So, it is basically the switching circuit that controls the motor. The transistors (T1 through T8) act as switches. The switching of these transistors is controlled by the software via data pins D0 through D7.

With this device one can control three parameters of the stepper motor: speed, direction and number of steps.
