The rated current is 2.6 A, peaking at 7.8 A under maximum load. This torque-speed envelope suits it for moderate-inertia indexing or constant-speed conveyor drives where the load-to-motor inertia ratio stays at or below 15 times. The power rate at continuous rated torque is 40.8 kW/s, which indicates how quickly the motor can accelerate its own inertia — useful when sizing for short move profiles. Insulation class 130 (B) means the winding withstands a continuous hot-spot temperature of 130 °C, standard for general-purpose servo applications without forced cooling. ## Enclosure, environment, and mounting constraints Totally enclosed with natural cooling and rated IP65, the motor body and shaft seal resist washdown and airborne dust — suitable for food-and-bev packaging lines or machining cells with coolant mist. The oil seal (J designation) further protects the bearing cavity from oil ingress, common on gearbox-coupled axes. Ambient operating temperature is 0 °C to 40 °C, non-condensing humidity 10 %RH to 80 %RH. Storage range extends to -15 °C to 70 °C. Vibration resistance is rated at 49 m/s² on X and Y axes, and altitude is limited to 2000 m — derate torque above that. The motor is for indoor use only, away from corrosive gas, flammable gas, and direct sunlight.","metaTitle":"Mitsubishi HG-KN43BJ-S100 Servo Motor, 0.4 kW, 3000 r/min, I","metaDescription":"Mitsubishi HG-KN43BJ-S100 servo motor, 0.4 kW rated output, 1.3 N·m torque, 3000 r/min rated speed, IP65 enclosure, with brake and oil seal.
