Yaskawa Electric Corporation USAPEM-03-YR21 AC Servo Motor

The Yaskawa Electric Corporation USAPEM-03-YR21 is a compact brushless AC servo motor from the USAPEM series, delivering ~300 W of continuous power for fast, precise motion in Motoman robot axis applications. Operating at ~200 VAC with a nominal current of ~2.7 A, it runs to ~3000 RPM and uses encoder-based closed-loop feedback for accurate speed and position regulation, with a flange-mount design and low inertia that enable quick response in tight automation spaces. Commonly deployed in robotic welding, material handling, pick-and-place, and CNC equipment, the USAPEM-03-YR21 serves as a replacement or retrofit motor for legacy Motoman axes (L/U axis configurations), providing consistent motion control and repeatability across automation tasks.
