Mitsubishi Electric HF-SP152B AC Servo Motor

The Mitsubishi HF-SP152B is a medium-inertia AC servo motor from the MELSERVO HF-SP series, delivering 1.5 kW of rated output at ~2000 RPM with ~7.16 Nm of torque for precise motion control. This AC servo motor runs on 200–230 VAC, 3-phase, and features a brushless enclosed design with an 18-bit absolute encoder and a built-in electromagnetic brake for reliable operation in demanding environments. With IP67 protection, a straight shaft, and flange mounting, it is suitable for CNC machines, conveyors, packaging equipment, and automated assemblies where repeatable positioning and smooth torque are critical. As a legacy model, HF-SP152B is commonly replaced by HG-SR152B on the modern iQ platform, with a weight of approximately 4–9 kg depending on configuration.
