Mitsubishi HG-KR13BJ Brushless AC Servo Motor with Brake

The Mitsubishi HG-KR13BJ (HG-KR13BJ) is a high-performance rotary brushless AC servo motor developed for use with Mitsubishi MELSERVO J3 series systems. Designed for precise positioning and motion control applications, this unit features a straight shaft configuration, an integrated electromagnetic holding brake, and a built-in 18-bit absolute feedback encoder. It is engineered to operate on a 200 V AC supply voltage class, delivering a rated output power of 850 W (0.85 kW) and a continuous rated current of 4.5 A. The motor provides a rated torque of 8.12 Nm at a rated rotational speed of 1,000 r/min, ensuring reliable dynamic response and accurate speed regulation across automated machinery. Built for demanding industrial environments, the HG-KR13BJ features an IP67 degree of protection to safeguard internal components against dust and moisture ingress. Mechanical installation is facilitated through a standard 130 mm by 130 mm mounting flange. The unit is rated for ambient operating temperatures ranging from 0 to +40 degrees Celsius, making it well-suited for industrial automation machinery, packaging lines, and machine tool feed mechanisms requiring secure vertical-axis holding and high-resolution position feedback.
