[Kevin Lynagh] is interested in tiny PCB stepper motors, and after reviewing the various projects and patents to-date, decided to give it a try himself. These are basically a stepper motor that’s been ...

Over the last two decades, stepping motors (or step motors) have increasingly been applied in electronic-control applications throughout all segments of the electronics industry. Its simplicity of ...

A new series of microstepping motor driver integrated circuits with an integrated step and direction translator interface has been developed specifically by to drive bipolar stepper motors. These new ...

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.

Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on a ...
