In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...

By closing the current loop, a step motor can operate with less power, improved efficiency, lower costs, and with reduced downtime due to the elimination of excessive motor heating.

How to Control a Stepper Motor Using a Computer. Stepper motors produce accurate, computer-controlled motion for applications such as robotic arms and paper-feed mechanisms for printers.
