Specification

The MITSUBISHI MELSERVO-J4 SERVOMOTOR 750W HG-KR73J is a cutting-edge AC servo motor engineered for high-speed, high-precision motion control in factory automation systems. Built on the advanced MELSERVO-J4 platform, this model features a 22-bit absolute encoder that delivers over 4 million pulses per revolution, enabling sub-micron positioning accuracy in applications such as CNC machining, robotics, packaging, and assembly lines. Its 750W power rating provides ample torque for medium-load axes, while the motor’s compact frame (flange size 60mm) allows for easy integration into tight machine layouts. The HG-KR73J also incorporates MITSUBISHI’s proprietary vibration suppression algorithms, which minimize mechanical resonance and reduce cycle times by up to 30% compared to previous generations. With an IP65 protection rating, it withstands coolant splashes, dust, and washdown environments, making it ideal for both dry and wet machining processes. Below is the detailed technical specification table for the HG-KR73J.
