Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Part 2 in a series of articles on motor control design focuses on how to reduce noise, one of the biggest challenges, in stepper motors. The amount of noise in a motor depends on the type of motor, ...

To better understand the origins of noise, we need to think about how the rotation movement takes place. When a stepper motor performs a step, it does not stop immediately but continues to move ...
