Mitsubishi Electric HC-RFS353BK Servo Motor

The Mitsubishi Electric HC-RFS353BK Servo Motor delivers 3.5 kW of continuous power in a flange-mounted, IP65-rated package, built for high‑precision, high‑torque motion in demanding automation environments. It operates at 200–230V AC, runs at approximately 2000 RPM, and uses an encoder system that can be incremental or absolute depending on the model, with an electromagnetic brake and self‑cooling for reliable long‑cycle operation. This servo motor is part of the HC‑RFS Series and is compatible with Mitsubishi MR-J2S Series servo drives, making it well suited for CNC machines, automated production lines, and packaging equipment that require stable speed control and accurate positioning. Common applications include CNC machining centers, injection molding machines, material handling systems, and robotics, where high power and precision are critical. Maintenance teams, OEMs, and system integrators often choose it for repair, retrofit, or replacement within Mitsubishi automation ecosystems. Common replacements include HC-RFS353B, HF-SP352B, and HG-SR352B.
