Mitsubishi HG-SR52G7K-1-45 Geared AC Servo Motor for HG-SR Series

The Mitsubishi HG-SR52G7K-1-45 (HG-SR52G7K-1-45) is a rotary AC servo motor equipped with a precision reduction gearhead, designed for high-performance industrial automation applications within the Mitsubishi Electric HG-SR series and compatible with MELSERVO systems. Serving as a geared servomotor, it provides controlled angular positioning, precise rotational speed, and multiplied output torque for demanding motion control tasks. This unit is also referenced as equivalent to model HKST52G5133. The motor incorporates an integrated 26-bit absolute feedback encoder that continuously tracks shaft position with high resolution, ensuring reliable closed-loop control without requiring home return sequences upon power-up. It features a straight motor shaft coupled to a high-precision gearhead providing a 1/33 reduction ratio with a rigid flange-type output interface for direct mechanical mounting. The reduction gearing enhances output torque while maintaining smooth motion dynamics and positional accuracy under varying mechanical loads. Engineered for precision machinery, packaging systems, assembly equipment, and multi-axis positioning stages, this geared AC servo motor delivers dependable operation and seamless integration into automated production environments.
