Mitsubishi Electric Corporation HC-SFS52B Servo Motor

The Mitsubishi HC-SFS52B is a medium-inertia AC servo motor from the MELSERVO HC series, engineered for precise motion control in industrial automation. It delivers 0.5 kW of rated output power from a 200 VAC class supply, with a rated current of about 3.2 A and a rated speed near 2,000 RPM (maximum speed ≈ 3,000 RPM). The motor provides a rated torque of ~2.39 Nm and a maximum torque of ~7.6 Nm, backed by a built-in absolute encoder (17-bit, ~131,072 pulses/rev) for reliable positioning feedback. It features a straight shaft with an electromagnetic brake, flange mounting on a ~130 mm frame, and an IP65 protection rating, with operating temperatures from 0 °C to 40 °C. This servo is commonly used in CNC machines, robotics, conveyors, and automated production equipment where smooth motion and repeatable, stable torque are required, and it is discontinued.
