Mitsubishi Electric HF-KE43KW1-S100 AC Servo Motor

The Mitsubishi Electric HF-KE43KW1-S100 AC Servo Motor delivers 400 W of rated power at 3000 RPM, with a built‑in electromagnetic brake for reliable holding and precise motion in automated systems. It is designed for precision‑driven applications in CNC machines, packaging equipment, robotics, conveyors, and assembly lines where accurate position, speed, and torque control matter. This HF‑K series motor uses a 3‑phase input in the approximately 100–200 V class, draws about 2.9 A, and provides a medium torque class that is application dependent, with a high‑resolution feedback encoder and a keyway shaft for reliable coupling. Its flange‑mount design is self‑cooled, weighing around 1.3–1.4 kg, and it carries an industrial‑grade protection rating typical for servo motors. The HF-KE43KW1-S100 is commonly used in pick‑and‑place systems, semiconductor equipment, conveyors, and automation machines, and is a common replacement for legacy Mitsubishi servo motors such as HF-KP43K, HF-KN43K, and HC-KFS43. This model is listed as discontinued.
