Yaskawa Electric Corporation SGMRS-30A2A-YR11 AC Servo Motor

The Yaskawa SGMRS-30A2A-YR11 AC Servo Motor, rated at 2.9 kW with a base speed of 1500 RPM, is a brushless servo motor from the Sigma Series designed for high-torque, precision motion in demanding industrial automation systems. It operates on 200 VAC three-phase and draws about 22.7 A, delivering approximately 18–19 Nm of torque in its 1500 RPM class. This motor is built for heavy-duty control tasks and is commonly deployed in Motoman robotic systems, CNC machinery, large-scale automated production equipment, and material handling lines where load handling, accuracy, and durability are critical. The encoder configuration supports absolute and incremental signaling for robot-specific setups, enabling reliable position feedback across complex motion profiles. With a flange-mount design, this unit typically weighs roughly 14–25 kg depending on configuration and packaging. Common replacements include the SGMRS-30A2A-YR12, SGMGH-30A2A-YR35, and SGMGV-30D3A61, offering parallel performance characteristics within the same family.
