Mitsubishi HG-SR52K Rotary AC Geared Servo Motor for MELSERVO Systems

The Mitsubishi HG-SR52K (HG-SR52K) is a rotary AC servo motor engineered with an integrated high-precision gear head and a straight shaft output for industrial motion control applications. Built for demanding automation environments, this geared servomotor integrates a 26-bit absolute feedback encoder to provide precise angular positioning, smooth rotation, and reliable closed-loop control without requiring reference homing cycles. It features a 1/11 gear reduction ratio, optimizing output torque delivery and velocity regulation for high-load and continuous-duty positioning tasks. Designed by Mitsubishi Electric, the HG-SR52K is compatible with high-performance drive architectures, including MELSERVO systems, and serves as an equivalent functional alternative to the HKST52G7111 configuration. The motor assembly combines a rugged rotary motor build with a specialized gear unit, ensuring dependable power transmission and torsional rigidity in machinery such as packaging equipment, material handling conveyors, robotics, assembly lines, and machine tools. By coupling an absolute multi-turn feedback system with a precision gearhead, this servo motor ensures exceptional operating efficiency, accurate speed synchronization, and minimal backlash across varied industrial manufacturing processes.
