Project 7.21—Stepper Motor Control Project—Simple Bipolar Motor Drive
The Bipolar Stepper motor is similar to the unipolar motor discussed in previous projects. The bipolar consists of two coils, but there is no center tap. As a result of this, the bipolar motor requires a controller where the current flow through the coils can be reversed. A bipolar motor is capable of a higher torque since entire coils may be energized, not just half of the coils. Bipolar stepper motors are usually controlled using H-bridge circuits where the current flow through the coils can easily be reversed.
Project Description
In this project, a bipolar stepper motor is used. The motor is rotated 10 revolutions in one direction, then stopped for 5 s, and then rotated 10 ...
