Mitsubishi Electric Corporation HC-SF81 Servo Motor

The Mitsubishi HC-SF81 servo motor is a 750W AC servo motor engineered for high-precision speed and position control in automated systems such as CNC machines, robotic arms, conveyors, and packaging lines. Sized for 200V class operation, it uses an incremental encoder and delivers a rated speed of 3000 RPM with a maximum speed of 4500 RPM. With IP65 protection (excluding shaft opening), self-cooled cooling, a straight shaft with key, and flange-mount configuration, this motor is built for rugged industrial environments. Insulation class is B and it's designed for Mitsubishi MELSERVO drives in MR-J2 and MR-J3 series, ensuring reliable integration in existing Mitsubishi automation setups. Common replacements include Mitsubishi HC-SFS81 and HC-KFS73. Common applications include CNC machining centers, robotic arms, conveyor systems, pick-and-place machines, and packaging equipment where consistent torque and responsive control are critical to production quality.
