Searching the multitude of available programmable motion controllers for one that is ideal for micro stepper motors with phase currents of sometimes less than 100 mA was once a real challenge. The new ...

Designers turn to stepper motors when they need to move a load a precise position and hold that position without jitter. Stepper motors focus microscopes, position lasers, keep CNC machining ...

The A4979 is a flexible microstepping motor driver with built-in translator for easy operation. It is a single-chip solution, designed to operate bipolar stepper motors in full-, half-, quarter- and ...

The question is: how to ‘cnc’ a manual Sieg X1 milling machine – the so called ‘micro mill’ that comes out in so many guises including the Clarke CMD10 featured here, available from Machine Mart, but ...

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.
