Mitsubishi HC703S Foot-Mounted Geared AC Servo Motor for MELSERVO Series

The Mitsubishi HC703S (HC703S) is an AC rotary geared servo motor designed for precise positioning and motion control in industrial drive systems. Operating within Mitsubishi Electric drive architectures such as the MELSERVO series, this motor-reducer assembly provides reliable torque multiplication and speed reduction for automated machinery. It is functionally equivalent to the HKST702G1H117 unit and integrates with compatible MELSERVO-J5 series drive setups. The HC703S features an integrated 26-bit absolute feedback encoder that delivers high-resolution position detection without requiring external homing routines after power cycles. For mechanical power transmission, the unit includes a shaft with a keyway and is equipped with a standard 1/17 ratio reduction gearhead. It utilizes a foot-mounted reducer output configuration, ensuring rigid and stable mechanical installation across diverse automation frames. Typical applications include precision conveying, material handling, assembly systems, packaging automation, and multi-axis industrial motion control where compact gearing, high torsional stiffness, and absolute position tracking are critical.
