Unipolar stepper motors

This video discusses the differences in the wiring of a unipolar and bipolar stepper motor, two common wirings of a unipolar stepper motor, and our solutions for driving a unipolar stepper. We offer integrated low-side drivers designed for unipolar steppers. This video also discusses two methods of driving a unipolar stepper with a bipolar driver as well as how to drive a unipolar stepper with a four channel half-bridge driver.

Great video! It helped a lot with my mechatronics class.

Looks like the current direction in bipolar schematic is wrong. it always flows to ground.

Why does a stepper motor driver use step/dir and not sin/cos?
