Mitsubishi HG-KNS73J AC Servo Motor for HG Series

The Mitsubishi HG-KNS73J (HG-KNS73J) is an AC servo motor manufactured by Mitsubishi Electric for the HG Series and compatible with the MELSERVO J3 series motion control architecture. Designed to deliver motion performance equivalent to 1 kilowatt, this unit is equipped with an integrated dynamic brake and built-in regenerative resistor functionality to support controlled deceleration and reliable energy dissipation in demanding motion profiles. It serves vital motion control tasks in industrial automation machinery, positioning systems, and automated production lines where consistent speed and positioning accuracy are essential. As a discontinued spare part, the HG-KNS73J provides a direct replacement solution for existing machinery and automation lines, helping maintenance engineers keep critical equipment operational without requiring costly system redesigns or drive retrofits. Typical applications include CNC machinery, packaging lines, material handling systems, and automated manufacturing cells operating on Mitsubishi Electric servo platforms.
