grbl is stepper motor controller firmware for three-axis cnc machines, intended to run on Arduinos with a motor driver add-on board. Engineer in Wonderland cnc-related blogs are indexed here It is the ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

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 ...

This file type includes high-resolution graphics and schematics when applicable. Millions of small electrical devices with built-in motor-driven mechanisms, used daily around the world, rely on ...

Stepper motors are now being used more frequently in industrial environments. Increased performance and reduced size make them increasingly attractive, and their application is no longer limited to ...

Developers, makers and hobbyists that are looking for a way to control up to four motors using their Raspberry Pi mini PC. May be interested in a new control board that has been created by Justin ...

A new motor driver featuring pulse-width modulation (PWM) and serial interfaces ensures quiet and robust motor operation in industrial and consumer applications. The motor driver IC, supporting both ...

TRINAMIC Motion Control's new TMC2660 stepper motor driver IC supports motor drive currents up to 4A. The new IC integrates both a pre-driver for real-time calculation of motor coil current values, ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...
