Mitsubishi Electric HC-KFS73 Low Inertia AC Servo Motor

The Mitsubishi Electric HC-KFS73 Low Inertia AC Servo Motor is a brushless, high-precision actuator designed for rapid, accurate motion control in industrial automation, including CNC machines, robotics, conveyors, and automated production equipment. It delivers 0.75 kW (750 W) of rated output power, a rated speed of 3000 RPM with a maximum around 4500 RPM, and a rated torque of about 2.4 Nm (maximum about 7.2 Nm), with a built-in encoder (absolute or incremental depending on variant), a flange-mount design with a straight or keyed shaft (variant dependent), natural or fan-assisted cooling, and an operating range of 0 °C to 40–55 °C with IP65 protection. Common replacements include HC-KFS73B, HG-KR73B, and HF-KP73, making it suitable for upgrades, replacements, and new installations that demand high responsiveness and repeatable positioning.
