Mitsubishi Electric Automation HG-RR503 AC Servo Motor

The Mitsubishi HG-RR503 AC servo motor delivers precise position, speed, and torque control in automated systems, enabling accurate motion coordination in CNC machines, robotics, packaging equipment, and automated assembly lines. The motor is in the 0.5–0.8 kW class and runs on AC supply typically 200–230 VAC, with a built-in high-resolution encoder for position and speed feedback that supports closed‑loop control with drives. It features a standard flange-mount chassis with a keyed shaft for precise coupling, industrial‑grade insulation, and is designed for industrial environments and operating temperatures. It is widely used in pick‑and‑place systems, gantry and indexing machines, printing and labeling equipment, and material handling conveyors where encoder feedback and repeatable motion are critical. Common replacements include Mitsubishi HC-MFS50 servo motor, Yaskawa SGMAV-04ADA61, and Panasonic Minas A5 400 W servo motor.
