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 ...

Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers. They require current pulses delivered through a special ...

Featured in this project is the control of a stepper motor with its speed, direction, and step size by sending some signals through the parallel port. The project provides better understanding and ...

The growing availability of customizable options for motors allows engineers to tailor motors to specific application needs, while modular designs simplify integration and reduce development time.

[Neumi] over on Hackaday.IO wanted a simple-to-use way to drive stepper motors, which could be quickly deployed in a wide variety of applications yet to be determined. The solution is named Ethersweep ...

Its modular, space-qualified design supports both two-phase and three-phase motor configurations, allowing integrators to ...

After using an oscilloscope to confirm that stepper motors driven backward produced an alternating current, University of Maryland senior Josh Sheldon decided to turn the resulting waveforms into ...

A new series of microstepping motor driver integrated circuits with an integrated step and direction translator interface has been developed specifically by to drive bipolar stepper motors. These new ...

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 ...

The fundamental circuit shown in Figure 1 generates timing for a two-phase stepper motor from an oscillator, as well as a direction (forward or reverse) signal. Figure... The fundamental circuit shown ...
