Mitsubishi Electric HC-MF73K-D53 AC Servo Motor

The Mitsubishi HC-MF73K-D53 AC Servo Motor is a 750 W, low-inertia servo in the HC-MF Series designed for Mitsubishi MELSERVO motion control systems and compact automation applications with an electromagnetic brake (D53). It operates from a 200 V class supply, delivers 3000 rpm rated speed (up to 4500 rpm maximum), and uses an incremental encoder for precise position feedback. Features include a permanent magnet AC servo motor with a straight shaft and key, IP55 protection (shaft area excluded), natural cooling, and flange mounting, compatible with Mitsubishi MR-J2S and MR-J3 drives. Common applications include CNC feed axes, pick-and-place machines, semiconductor manufacturing equipment, packaging and labeling systems, indexing tables, robotic mechanisms, and assembly automation or factory automation machinery requiring 750 W of power and a holding brake; maintenance teams, OEMs, and system integrators often use it for replacement, retrofit, or motion-system repair to restore positioning accuracy.
