Mitsubishi Electric Corporation HC-RFS353K Servo Motor

The Mitsubishi HC-SFS702K servo motor is a high-capacity AC servo motor in the MELSERVO HC-SFS series, designed for heavy-duty motion control with high torque and stable operation. It offers a rated output of 7.0 kW at roughly 2000 RPM and operates on a voltage class of about 200–230 VAC with a rated current near 35 A, featuring a high-resolution absolute encoder and a keyed (K) shaft. Built in an industrial enclosed design with flange mounting, it weighs approximately 9 kg (about 20 lb) and is typically IP65-rated (excluding the shaft), making it suitable for CNC machining centers, large conveyors, industrial robotics, large packaging systems, and automated production lines where precise positioning and durable torque are essential. This is a discontinued / legacy model, with common replacements including Mitsubishi HG-SR702B, HF-SP702, and HC-SFS702.
