Yaskawa Electric Corporation SGMS-20A6AB AC Servo Motor

The Yaskawa SGMS-20A6AB AC Servo Motor is a 2000 W Sigma-series servo unit designed for precise speed and position control in industrial automation systems. With a 3000 RPM base speed and 6.36 Nm of rated torque, it operates from a 200 VAC three-phase supply and draws about 12.4 A, featuring a brushless AC servo motor architecture and an incremental encoder (Sigma series standard) for accurate feedback. Its flange-mount design supports continuous-duty operation, making it well-suited for CNC machines, robotic axes, conveyors, and other automated production equipment where reliable torque and repeatable positioning are critical. As a legacy Yaskawa installation, it frequently serves as a direct drop-in replacement in existing systems and aligns with common replacements such as Yaskawa SGMGH-20ACA6B, Yaskawa SGMPS-20ACA61-E, and Yaskawa SGM7G-20A.
