Mitsubishi HG-SR702G1-1-59 AC Servo Motor for MELSERVO-J4 Series

The Mitsubishi HG-SR702G1-1-59 (HG-SR702G1-1-59) is a high-performance AC servo motor designed for demanding motion control tasks in factory automation environments. Belonging to the HG-SR series, this medium-inertia servo motor operates on a 200 V class power supply and delivers a nominal output of 7 kW (7000 W) with a rated current of 37 A. It features a specialized G1 reduction gearbox with a 1:59 gear ratio, providing high torque output and precise speed control for heavy-duty industrial machinery. Engineered for seamless integration with Mitsubishi Electric MELSERVO-J4 series servo drives, such as the MR-J4-700TM-ECT and equivalent multi-network amplifiers, the HG-SR702G1-1-59 supports advanced networking capabilities including EtherCAT communication when paired with compatible drive units. The motor provides reliable dynamic braking and works in tandem with built-in regenerative resistance circuits on matching drives to maintain stable deceleration and thermal management. Typical applications include CNC machine tools, automated material handling, metal processing, packaging equipment, and industrial rotary positioning tables that require rigid motion profiles, smooth low-speed operation, and substantial mechanical holding capability under continuous factory operating conditions.
