Yaskawa Electric Corporation USASEM-03YRW22 AC Servo Motor

The Yaskawa Electric Corporation’s USASEM-03YRW22 is a compact brushless AC servo motor from the USASEM series, engineered for Motoman robot axes controlled by MRC controllers and CNC automation equipment that require about 300 W of continuous power and precise speed and position regulation. It delivers about 3000 RPM at ~200 VAC, featuring a low-inertia, high-speed design and encoder-based closed-loop feedback (UTMAH / UTOPI typical) in a flange-mounted, totally enclosed, self-cooled package suitable for continuous operation. Typical applications include robotic welding systems, material handling robots, CNC machinery, and automated production lines where coordinated axis motion and reliable feedback are essential. Common replacements include Yaskawa USASEM-03YRS22, SGMPH-03A1A-YR11, and SGMJV-04ADA21.
