Yaskawa SGMRS-12A2B-YR11 AC Servo Motor With Encoder

Yaskawa SGMRS-12A2B-YR11 AC servo motor with encoder delivers 1.15 kW of continuous power in a Sigma-III package, designed for precise speed and torque regulation in industrial robotic and CNC motion control systems. This brushless 200 VAC (3-phase) servo motor uses an absolute encoder (UTSAE series typical) for reliable position feedback, with a rated speed of 2000 RPM and a rated torque of 5.49 Nm, drawing roughly 6 A under load. Weighing about 8–9 kg and configured for flange mounting, it emphasizes low-speed, high-torque performance and is suitable for continuous operation in robotics and automation environments. Common applications include Motoman robot axes, robotic welding systems, CNC machining centers, material handling equipment, and automated production lines where synchronized multi-axis motion and encoder feedback are critical. The model belongs to Yaskawa’s Sigma-III SGMRS family and is commonly used as a replacement in maintenance, rebuilds, and retrofit projects for legacy automation platforms. Verified replacements within the same family include Yaskawa SGMRS-13A2A-YR11, SGMRV-13ANA-YR11, and SGMGH-12A2A-YR15, illustrating compatibility options for upgrades or spare parts while preserving performance and control characteristics.
