Mitsubishi Electric HG-SR102 Servo Motor

The Mitsubishi Electric HG-SR102 Servo Motor is a brushless AC servo motor designed for precision motion control, delivering accurate speed, position, and torque in demanding automation environments. Commonly installed in robotics, CNC machines, packaging systems, and automated assembly lines, it enables quick response and tight positional accuracy for high-speed, repeatable movements, ensuring reliable performance in automated processes. Key specifications include a ~100 W class rated power (model dependent), a 200 V AC class supply, a keyed output shaft for coupling, flange-mount housing, industrial-grade insulation, and encoder feedback (model dependent: incremental or absolute), with typical speeds in the 3000–6000 RPM range. It features a robust design suitable for industrial environments and is widely used in precision motion control for robotic arms, pick-and-place systems, labeling and printing machinery, indexing tables, conveyor positioning, and machining centers. Common replacements in the Mitsubishi ecosystem and similar-class options include HG-SR103 and HC-MF102, as well as Yaskawa SGMAV-A5A3A servo motors, which are used for replacements, retrofits, and system upgrades to maintain or improve automation performance.
