Mitsubishi HG-KR73J AC Rotary Servo Motor for MELSERVO-J4 Series

The Mitsubishi HG-KR73J (HG-KR73J) is an AC rotary brushless servo motor engineered for precise motion control within the Mitsubishi Electric MELSERVO-J4 series. Equipped with a straight shaft, an integrated electromagnetic brake, an oil seal, and a built-in 22-bit absolute feedback encoder delivering 4,194,304 pulses per revolution, this motor provides high positioning accuracy and secure holding capabilities during power-off conditions. Operating on a 400 VAC supply voltage class, the motor delivers a rated output of 3.5 kW (3,500 W), a rated torque of 10.5 Nm, and a rated speed of 3,000 rpm, drawing a rated current of 8.3 A. Built for harsh industrial environments, it features an IP67 protection rating, a standard 130x130 mm flange mount, and two MS-type connectors for secure power and feedback connections. Designed to operate within an ambient temperature range of 0 to +40 degrees Celsius, this servomotor is equivalent to the HGJR3534B model and is widely utilized across automated manufacturing machinery, material handling systems, packaging equipment, and industrial robotics requiring high-performance positioning.
