Mitsubishi HG-SR52G1H-1-43 Geared AC Servo Motor with Brake

The Mitsubishi HG-SR52G1H-1-43 (HG-SR52G1H-1-43) is an AC rotary geared servo motor designed for precise motion control in industrial drive systems and automated machinery. Built as part of Mitsubishi Electric HG-SR series, this geared servo motor features a factory-integrated electromagnetic holding brake and a high-resolution 26-bit absolute feedback encoder to provide accurate shaft positioning and reliable hold during power-off conditions. It is equipped with a high-precision gear head offering a 1/21 gear reduction ratio with a straight shaft output, delivering optimized torque multiplication and low-backlash speed reduction for heavy-duty motion applications. Engineered to support demanding automation tasks, the unit provides seamless integration with compatible Mitsubishi MELSERVO drive systems and is referenced as an equivalent replacement for HKST52BG7121 models. It is typically deployed across industrial robotics, CNC positioning axes, automated material handling, packaging machinery, and assembly lines requiring high-torque rotary movement with integrated fail-safe braking.
