Mitsubishi HF-SP51B AC Servo Motor with Brake

The Mitsubishi HF-SP51B (HF-SP51B) is a medium-inertia rotary brushless AC servo motor designed for precise motion control applications within the HF Series. Engineered for compatibility with Mitsubishi servo drive systems, this industrial motor delivers reliable dynamic performance in machine tools, packaging lines, and automated assembly equipment. It features a straight shaft, an integrated electromagnetic holding brake, and a built-in 18-bit absolute encoder providing high-resolution position feedback of approximately 260,000 pulses per revolution. The motor operates on a 200 VAC power supply class with a rated output capacity of 3,000 W (3 kW). Key operational ratings include a rated current of 10.7 A, a rated rotational speed of 2,000 r/min, a continuous rated torque of 14.3 Nm, and a stall torque of 22.5 Nm. Built with a durable 176 x 176 mm mounting flange, the unit provides an ingress protection rating of IP67 to withstand harsh plant environments with dust and moisture. It is designed to operate reliably within an ambient operating temperature range of 0 to +40 degrees Celsius.
