The model designation decodes as HG-KN series, 0.75 kW, 3000 r/min base speed, with an electromagnetic holding brake and an oil seal installed on the output shaft. Maximum speed is 6000 r/min with an instantaneous permissible limit of 6900 r/min; the power rate at continuous rated torque is 41.0 kW/s, which sets the acceleration ceiling for the coupled load inertia. The recommended load-to-motor inertia ratio is 15 times or less — exceeding this ratio requires a larger frame or a gearbox to keep the servo loop stable without excessive gain tuning. ## Environmental qualification and mounting constraints The motor is totally enclosed, natural cooling, rated IP65 — the housing and shaft seal resist washdown and dust ingress, but the IP rating applies only when the connector is mated and the cable gland is properly torqued. Ambient operation is 0 °C to 40 °C, non-condensing, with storage from -15 °C to 70 °C; the altitude ceiling is 2000 m above sea level without derating. Vibration resistance is 49 m/s² in the X and Y axes, and the motor carries a V10 vibration rank — this is the standard grade for general-purpose servo applications and is suitable for direct machine mounting without additional isolation on most frame structures. The insulation class is 130 (B), which limits the winding temperature rise to 80 K above a 40 °C ambient under rated continuous load.","metaTitle":"Mitsubishi HG-KN73BJ-S100 Servo Motor with Brake, 0.75 kW","metaDescription":"Mitsubishi HG-KN73BJ-S100 servo motor, 0.75 kW, 2.4 N·m rated torque, 3000 r/min, with electromagnetic brake and oil seal.
