Mitsubishi HG-SR52G7K-1-5 Geared AC Servo Motor

The Mitsubishi HG-SR52G7K-1-5 is a rotary alternating current geared servo motor designed for demanding precision automation, positioning, and motion control tasks. Built within Mitsubishi Electric's high-performance servo motor lineup and compatible with advanced drive architectures such as the MELSERVO series, this geared motor unit functions as a direct drop-in and functional equivalent to the HKST52G5145 motor assembly. The motor integrates a high-resolution 26-bit absolute feedback encoder that delivers continuous, exact shaft position tracking without requiring repeated homing procedures after power loss. Mechanically, the HG-SR52G7K-1-5 features a straight shaft construction coupled to a factory-fitted high-precision gearhead offering a 1/45 reduction ratio. The reduction gearhead incorporates a durable flange-output configuration, enabling significant torque multiplication, lower output shaft speed, and exceptional backlash characteristics. These mechanical attributes make the assembly well-suited for heavy-duty machine tool axes, index tables, packaging machinery, transfer equipment, and material handling systems requiring high torsional rigidity. By combining an advanced optical encoder and a robust reduction head, the unit provides reliable motion stability and outstanding dynamic response in diverse industrial drive environments.
