Based on the Motorola (now Freescale) heavily used but obsolete SAA1042 stepper-motor-driver IC, this Design Idea describes a CPLD (complex-programmable-logic-device)-based implementation of a stepper ...

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 ...

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 ...

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 ...

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 ...

The world is digital today, and most information is represented in numbers. However, human nature is more “analog” and information is better represented in the old-fashioned way, using pointer gauges ...

A stepper motor driver provides up to 5 A per phase from a high bus voltage with sophisticated current control, delivering high torque over a range of speeds. The STAC5 is intended for use in such ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...

Nanotec has introduced a driver for stepper and brush-less dc (BLDC) motors with sensor-less closed-loop and field-oriented control (FOC). Intended for steppers from NEMA 14 to NEMA 34 and BLDC motors ...

Mikroe has added a smart 85V 10A stepper motor driver to its range of interchangeable ‘Click’ boards. Called Power Step 2 Click, the board “is based on the powerSTEP01, a 1/128 microstepping ...

We’ve seen plenty of motor projects, but [Jeremy]’s DIY Tubular Linear Motor is a really neat variety of stepper motor in a format we certainly don’t see every day. It started as a design experiment ...
