Mitsubishi Electric HC-MFS43B-S13 Servo Motor

The Mitsubishi Electric HC-MFS43B-S13 AC servo motor delivers fast response and precise speed, torque, and position control in industrial automation. Key specifications include 400 W rated power, ~122 V AC (3-phase typical), ~2.8 A rated current (9 A peak), 3000 RPM rated speed (up to 4500 RPM), and ~1.3 Nm rated torque (up to 3.8 Nm), with a high-resolution encoder for accurate feedback. The S13 variant includes an electromagnetic brake, and it mounts on a flange with a standard keyed shaft, designed to operate from 0–40 °C. Common applications span CNC machines, robotics, packaging equipment, pick-and-place systems, indexing conveyors, gantry setups, and automated production lines where repeatability and tight cycle times are critical. Related replacements include Mitsubishi HC-MFS43 and HC-SFS43 servo motors and Yaskawa SGMAV-04A3A6C.
