Mitsubishi HC-KFS73BG1 AC Servo Motor with Brake

The Mitsubishi HC-KFS73BG1 (HC-KFS73BG1) is a brushless rotary AC servo motor engineered for high-precision industrial motion control within the Mitsubishi MELSERVO series. Featuring an integrated electromagnetic holding brake and a straight shaft design, this servomotor provides reliable holding and dynamic positioning across demanding automated systems. Feedback is managed via an integrated absolute rotary encoder capable of 1,000,000 pulses per revolution, ensuring high resolution and dependable position tracking without requiring homing cycles upon startup. Operating on a 200 V AC supply voltage class, the motor delivers a rated output of 11 kW with a rated current of 24.6 A. It generates a rated torque of 35 Nm, a maximum stall torque of 260 Nm, and runs at a rated rotational speed of 3,000 RPM. Built to withstand harsh operating environments, the unit is housed with an IP67 degree of protection against dust and liquid ingress and utilizes a standard 220 x 220 mm mounting flange. The HC-KFS73BG1 serves as a high-performance replacement motor across robotics, automated tooling, assembly machinery, and industrial positioning equipment.
