Applied Motion Products: Miniature stepper drive

The STR3 miniature step motor drive from Applied Motion Products solves two problems in one. It addresses the problem of slow step motors that vibrate too much, and it addresses space-constrained applications where bulkier drives just won’t fit.

The STR3 utilizes a proprietary current control algorithm that optimizes motor performance, providing smooth motion over a wide speed range. Its extremely compact design means it’s possible to mount the drive just about anywhere, such as directly on the machine frame or tucked into small spaces between other components.

Designed for OEMs that require best-in-class performance and a high level of integration, the STR3 is intended to be used deep within the heart of the machine. Accepting industry-standard digital control signals (pulse & direction), the drive can be married to the widest range of embedded and discrete controllers. Easily configured using dip switches, there is no software required for setup. Powered by 12 to 48 volts DC, it can be easily specified into mobile systems as well as onto the plant floor. Capable of providing up to 3.0 A/phase it can run a wide range of 2-phase step motors, from the smallest NEMA 8 to larger NEMA 23 and NEMA 24 frame motors.
