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 ...

When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

This is a tool that we hadn't thought much about before until we saw it in action. Removing the balancer from a V-8 engine, especially in the tight confines of a truck's engine compartment, can be ...
