Yaskawa Electric Corporation USASEM-08YRS12 Servo Motor

The Yaskawa Electric Corporation USASEM-08YRS12 is a brushless AC servo motor from the USASEM series delivering 771 W of continuous power, 2.45 Nm of torque, and 3000 RPM at 200 VAC. It uses encoder-based closed-loop feedback and a flange-mount, low-inertia, high-speed design to provide precise speed and torque regulation for Motoman robot axes (R/B/T axis typical). This servo motor is used in industrial automation environments where accurate positioning and reliable torque output are required and is commonly deployed in robotic welding systems, material handling robots, CNC machinery, and automated production lines. It is suitable for maintenance teams, OEMs, and integrators seeking replacements, system repairs, or retrofit of legacy robotic systems, and it supports continuous operation under standard duty cycles. The unit weighs approximately 14–15 lbs in shipping weight. Common replacements include SGMPH-08A1A-YR11 and SGMGV-08D3A6H.
