Users of step motors will praise their simplicity, excellent positioning skills, and economy. They may also lament certain characteristics of step motor performance. For example, traditional step motor systems run open loop which means the drive electronics supply constant current to the motor whether there is a demand for torque from the load or not. What happens to that current when there’s no torque demand? It is lost as heat.

We are very pleased to announce the introduction of our most compact stepper drive to date. The STR3 miniature advanced stepper drive offers many of the great features of our larger drives, but in an ultra-compact package designed for OEMs demanding high performance and a competitive price point.

If you missed Applied Motion Products at ATX West in Anaheim, CA this past February 9-11 you can still catch a glimpse of the action. A video recap of the show is available here.

That’s the answer to one of the more common questions we get at Applied Motion. We maintain inventory in our California warehouse as a commitment to zero lead time for our most popular set of step motors. The CORE step motors are the best choice to match with our drives and have been fully characterized with speed-torque curves with recommended drives. Speed-torque curves are important for every project because they are the most accurate representation of performance for a given motor and drive combination.
