Mitsubishi HG-MR053 AC Rotary Brushless Servo Motor for MELSERVO-J4

The Mitsubishi HG-MR053 (HG-MR053) is an AC rotary brushless servo motor designed for use with Mitsubishi Electric MELSERVO-J4 series motion systems. Engineered for high-precision industrial positioning and velocity control, this motor delivers a rated output of 750 W (0.75 kW) with a rated torque of 2.4 Nm and a rated speed of 3,000 r/min. Operating on a 400 V AC supply voltage class with a rated current of 2.8 A, it features an integrated 22-bit absolute feedback encoder providing high-resolution positioning equivalent to 4,194,304 pulses per revolution. Built for demanding industrial environments, the motor includes a keyed shaft, an integrated oil seal, and an IP67-rated enclosure suitable for harsh operating conditions. Electrical interfacing is achieved through two standard MS-type connectors. It mounts via a 90x90 mm flange and operates reliably within an ambient temperature range of 0 to +40 °C. Functionally equivalent to the HGJR734K specification, the HG-MR053 serves industrial machinery requiring accurate motion control and dynamic response.
