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 ...

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 ...

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 ...

Improved microstepping accuracy, and lower motor audible noise and heating results from advanced techniques for current management. Stepper motor motion systems, formerly relegated to low-speed, high ...

Sometimes less is more. Here, a quarter-step switching logic sequence for stepper motors offers several significant advantages over full-and halfstep modes—higher resolution, smoother drive, minimal ...

Zilog, introduced its new Microstepper Motor Reference Design to expand its portfolio to reference designs that target motor control applications and provide accelerated time-to-market solutions.

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.
