Yaskawa Electric Corporation SGMAH-04A1A-HL11 Servo Motor

The Yaskawa SGMAH-04A1A-HL11 servo motor is a 400 W AC servo motor in the Sigma-II (SGMAH) family, engineered for high-speed, high-accuracy motion in mid-power industrial automation. Used with Sigma-II AC servo drive systems, it delivers precise speed, torque, and positioning for CNC machines, robotics, packaging equipment, and automated production lines. Key specifications include a 60 mm frame size, three-phase 200 V operation, rated output of 400 W, rated torque of 1.27 N·m, and a rated speed of 3000 RPM, with encoder feedback (incremental or absolute depending on configuration). The motor is self-cooled, flange-mounted, with shaft options of straight or keyed depending on variant, and features a low-inertia design for fast acceleration and response. Common replacements include Yaskawa SGMAH-04A1A21, Yaskawa SGM7J-04AFA21, and Yaskawa SGMJV-04ADA21.
