Kollmorgen's POWERMAX II series stepper motors, like most other Kollmorgen stepper motors, are now UL recognized. This enables OEMs who build UL-certified equipment to integrate high-performance stepper technology into existing designs without requiring re-certification. These NEMA 23 (60 mm) step motors are available in half, single and two stack configurations, and provide holding torques from 42 to 253 oz-in. Speeds up to 3,000 RPM more than satisfy the velocity demands of most high torque applications.

"UL recognition on high-performance step motors is a relative rarity, so machine builders who might otherwise benefit from this technology are sometimes faced with choosing between moderate performance steppers or other motor options that are less than ideal for the application. So UL recognition of Kollmorgen's POWERMAX II step motors is significant in that it enables OEMs whose machines need to be UL-certified to improve machine operation with high-performance steppers, without having to re-submit their equipment to UL for re-certification," explains Josh Inman, product manager.
