Mitsubishi Electric manufactured the HG-SR352 AC servo motor belongs to the MELSERVO J4 series products, which is intended for use in a wide range of industrial automation applications. It is a servo motor with medium inertia and capacity; the moment of inertia is 0.00786kg-m2 (78.6kg-cm2). The rated power output of the HG-SR352 servo motor is 3.5 kW (kilowatts), and has a rated current of 14 amps. Under normal operating conditions, the rated speed of the HG-SR352 servo motor is specified as 2000 RPM (revolutions per minute). In specific applications, the HG-SR352 servo motor can also operate at 3000 RPM maximum speed and 3450 RPM instantaneous permissible speed. The HG-SR352 servo motor operates on 3-phase AC voltage, which is commonly used in industrial power systems. The voltage rating of the motor is 200V AC to 240V AC (3-phase). The HG-SR352 servo motor lacks an electromagnetic brake to keep its shaft from moving when the motor is turned off. The HG-SR352 servo motor has a standard straight shaft shape that allows for easy connection to the drive mechanism. Still, it lacks an oil seal to prevent lubricating oil leakage from the motor and a keyway. It has a rated torque of 16.7 N-m and, maximum torque of 50.1 N-m. Its maximum radial load is 2058 N, and the maximum axial load is 980 N. The HG-SR352 servo motor has a 22-bit encoder and is housed in an IP67-rated enclosure. It uses a flange mounting setup. Overall, the Mitsubishi HG-SR352 servo motor is a powerful and robust medium-inertia and medium-capacity servo motor that can be used in a wide range of three-phase AC powered systems.
