It is sized for applications where fast acceleration and deceleration are needed on small to medium loads — typical for pick-and-place, indexing tables, and packaging machine axes. Rated output is 0.4 kW at 3000 r/min, with a rated current of 2.6 A. Maximum torque reaches 4.5 N·m, which gives the motor headroom for short-duration overloads during acceleration or reversing moves. ## Construction and environment The motor includes an oil seal (J suffix), so it can be mounted in gearbox or ball-screw assemblies where oil mist or splash is present. Vibration rank is V10, meaning the motor meets standard balance for general-purpose servo applications. Ambient installation is indoors, away from direct sunlight, corrosive gas, flammable gas, oil mist, dust, and dirt. Insulation class is 130 (B), which is the standard thermal class for servo motors in normal industrial environments.","metaTitle":"Mitsubishi HG-KR43J AC Servo Motor, 0.4 kW, 3000 r/min, 2.6","metaDescription":"Mitsubishi HG-KR43J AC servo motor, 0.4 kW rated output, 3000 r/min, 2.6 A, 4.5 N·m max torque, V10 vibration, with oil seal.
