The MITSUBISHI MELSERVO-J4 SERVOMOTOR 200W HG-KR23BJ is a low-inertia, small-capacity AC servo motor engineered for high-speed, high-precision applications in industrial automation. As part of the HG-KR series, this motor delivers a rated output of 0.2 kW and a rated torque of 0.64 N·m, with a maximum torque of 2.2 N·m to handle peak loads during acceleration. Its maximum speed of 6000 r/min and instantaneous permissible speed of 6900 r/min enable rapid positioning cycles, while the 23-bit absolute encoder ensures exceptional accuracy. The motor operates reliably in ambient temperatures from 0°C to 40°C and humidity levels between 10% and 80% RH (non-condensing), with storage capabilities from -15°C to 70°C. With a radial load capacity of 88 N and thrust load capacity of 59 N at the shaft extension (L=25 mm), it is built for robust mounting in compact machinery. The HG-KR23BJ is designed for continuous duty and is fully compatible with MR-J4 series amplifiers, making it a drop-in upgrade for demanding servo systems.
