When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

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 ...

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 ...

The MCST 3601 programmable motion controller is ideal for micro-stepper motors with phase currents that are sometimes less than 100 mA. The controller can precisely regulate phase currents from 10 mA ...

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.
