Mitsubishi Electric Corporation HG-RR203B AC Servo Motor

The Mitsubishi Electric HG-RR203B AC servo motor is designed for closed‑loop motion control, delivering precise position, speed, and torque control in automated systems. It features a built‑in high‑resolution encoder for position and speed feedback and is typically driven from 200–230 VAC with a rated power class of approximately 0.2–0.3 kW (platform dependent). The motor uses a standard flange mount and a keyed shaft for reliable mechanical coupling, and it is built with industrial‑grade insulation suitable for harsh environments and an industrial operating temperature range. HG-RR203B is designed for closed‑loop operation with feedback‑based drives and is widely used in CNC machines, robotics, packaging equipment, and automated assembly lines, including pick‑and‑place systems, gantry mechanisms, indexing conveyors, and printing/labeling machinery. Common replacements include Mitsubishi HC‑MFS23 and Yaskawa SGMAV‑04A3A6C.
