The Mitsubishi HG-KR73BJ is a low-inertia, small-capacity servo motor designed for high-performance motion control applications. With a rated output of 0.75 kW and a rated speed of 3,000 r/min, this motor is well-suited for systems requiring rapid acceleration and deceleration. It is equipped with an electromagnetic brake and an oil seal, providing enhanced operational safety and protection against contamination. The oil seal is applicable to HG-KR and HG-MR series models rated 0.1 kW and above, as well as HG-SR series models. However, when used with a gearbox, the oil seal is not included. Please note that the external dimensions of oil-seal-equipped HG-KR and HG-MR series motors differ from standard specifications.

The motor supports a maximum speed of 6,000 r/min and delivers a peak torque of 350% of the rated torque, enabling high torque output even at elevated rotational speeds—a feature exclusive to the HG-KR series. This capability ensures exceptional performance in applications demanding high-speed positioning and dynamic response.

The HG-KR73BJ incorporates a high-resolution absolute position encoder, offering 4,194,304 pulses per revolution (22-bit resolution). This advanced feedback device enables precise positioning and contributes to improved system accuracy and repeatability. The encoder provides reliable absolute position data, eliminating the need for homing routines after power-up.

In terms of environmental durability, the HG-KR, HG-MR, HG-RR, and HG-UR series models are designed with an IP65 protection rating, ensuring resistance to dust and water ingress. This makes the motor suitable for use in harsh industrial environments where exposure to contaminants or washdown conditions is a concern.

Overall, the Mitsubishi HG-KR73BJ servo motor combines high-speed performance, robust torque characteristics, precise feedback, and enhanced environmental protection, making it an ideal choice for demanding automation and motion control applications.
