Mitsubishi HG-RR503 Rotary AC Servo Motor for MELSERVO-JE Series

The Mitsubishi HG-RR503 (HG-RR503) is a brushless rotary AC servo motor designed for high-precision motion control within the MELSERVO-JE series automation platform. Delivering a rated power output of 400 W (0.4 kW) with a 200 V AC supply voltage class, this compact motor provides reliable dynamic performance across industrial positioning, robotics, packaging, and automated handling machinery. It operates at a rated rotational speed of 3000 r/min, generating a rated torque of 1.3 N·m at a continuous rated current of 2.6 A. The motor features a straight output shaft equipped with an integrated oil seal to prevent lubricant leakage and ingress of contaminants. High-resolution position detection is ensured by a built-in 17-bit absolute rotary encoder delivering 131,072 pulses per revolution for accurate closed-loop feedback. Built with a 60 x 60 mm mounting flange, the unit provides an IP65 degree of protection against dust and water jets. Engineered for standard factory environments, it is rated for ambient operating temperatures ranging from 0 to +40 degrees Celsius.
