Mitsubishi HG-RR503K AC Rotary Servo Motor for MELSERVO JE Series

The Mitsubishi HG-RR503K (HG-RR503K) is a brushless AC rotary servo motor engineered for precision motion control within Mitsubishi MELSERVO JE series drive systems. Operating on a 200 VAC supply voltage class, this compact motor delivers a rated output of 400 W (0.4 kW) with a rated torque of 1.3 N·m and a rated rotational speed of 3,000 r/min, drawing a rated current of 2.6 A. It features a straight shaft equipped with an integrated oil seal to prevent fluid and contaminant ingress during demanding industrial operations. High-precision feedback is provided by an integrated 17-bit absolute encoder with a resolution of 131,072 pulses per revolution, ensuring accurate positioning and stable dynamic response. Built with a 60 x 60 mm flange mount, the motor conforms to an IP65 protection rating, shielding the internal components from dust and water spray in harsh operating environments. It is calibrated for ambient operating temperatures between 0 and +40 degrees Celsius. The unit is suited for automated machinery, packaging lines, conveyors, and positioning equipment requiring compact and reliable servo performance.
