Yaskawa USASEM-01YRW11 AC Servo Motor

The Yaskawa USASEM-01YRW11 is an AC servo motor built for precise speed and position control in industrial robotics and CNC automation. Designed for use with Yaskawa Motoman systems that employ MRC series robot controllers, it delivers 77 W rated power with up to 1 kW peak, a rated speed of 3000 RPM, and about 2.1 A at 200 VAC, with FG feedback for accurate closed-loop regulation. This flange-mounted motor runs with natural convection cooling, weighs roughly 1.2–1.8 kg, and rotates clockwise. It serves robotic welding, material handling, CNC machinery, and automated production lines where coordinated axis motion and reliable feedback are required, and is a direct-fit replacement for older Motoman platforms. Common replacements include Yaskawa USASEM-01YRS11, SGMPH-01A1A-YR11, and SGMJV-01ADA21.
