Mitsubishi Electric HC-KFS43 AC Servo Motor

The Mitsubishi Electric HC-KFS43 AC Servo Motor is a brushless synchronous servo motor engineered for precise motion control in industrial automation. It delivers accurate speed, position, and torque control for applications requiring high responsiveness and repeatability, and is commonly used for replacement, retrofit, or system-performance upgrades in automated machinery. Key specs include a ~400 W class rated power, 200 V AC servo class, and a rated speed of roughly 3,000–6,000 RPM depending on configuration, with feedback from a high-resolution encoder (incremental or absolute variant). The motor features a keyed output shaft for couplings, flange mounting, industrial-grade insulation, and precision bearings designed for industrial environments. Common applications span robotics, CNC machines, packaging equipment, material handling, pick-and-place mechanisms, and automated assembly lines—supporting gantry motion, indexing tables, conveyor positioning, and tooling actuation. For compatibility and options, Mitsubishi HC-KP43B and HC-KFS43E are listed as common replacements, with Yaskawa SGMAV-A5A3A representing a comparable alternative.
