Rated output is 0.4 kW at 3000 r/min, with a rated current of 2.8 A and a maximum current of 7.8 A. Maximum torque hits 3.8 N·m. The motor includes an oil seal (J designation), making it suitable for applications where lubricant ingress is a concern. Control is sine-wave PWM current control — standard for this class of servo drive, delivering smooth torque at low speeds and quiet operation across the speed range. The general-purpose interface (A type) means it accepts standard pulse-train or analog speed/torque commands without a dedicated fieldbus module. The 0.4 kW rated output and 3000 r/min base speed match a 400 W motor frame — typical for small indexing tables, pick-and-place axes, or conveyor diverters where the load inertia is low. The 3.8 N·m maximum torque gives roughly 3× the rated torque for short bursts during acceleration or deceleration, which is enough for most light-duty positioning moves. The 2.8 A rated current sets the continuous thermal limit; the 7.8 A maximum current is what the amplifier can deliver transiently, so the upstream power supply and cabling must be sized for the peak draw, not just the continuous rating.","metaTitle":"Mitsubishi MR-JE-40A+HG-KN43J Servo System, 0.4 kW, 3000 r/m","metaDescription":"Mitsubishi MR-JE-40A+HG-KN43J servo amplifier and motor set, 0.4 kW rated output, 3000 r/min, 2.8 A rated current, 3.8 N·m max torque, sine-wave PWM control, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Drives"],"specifications":{"MR-JE":"Series","Series":"HG-KN (low inertia/small capacity)","Weight":"1.5 Kg","HG-KN43J":"AC Servo Motor","Oil seal":"J = With","MR-JE-40A":"MR-JE-_A Servo Amplifier","Product No":"MR-JE-40A+HG-KN43J","Rated speed":"3 = 3000 [r/min]","Manufacturer":"Mitsubishi Electric","Product Type":"MR-JE-_A Servo Amplifier + AC Servo Motor","Rated output":"4 = 0.4","Control method":"Sine-wave PWM control, current control method","Maximum current":"7.8","Shipping Weight":"4Kg","lifecycle_stage":"current","Rated current [A]":"2.8","Estimated Lead Time":"Usually ships in 1-10 working days.","Maximum torque [N•m]":"3.8","General-purpose Interface":"A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$634.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/def93a96da2f69b33ab72c9582e34ddc.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/MR-JE-40A%2BHG-KN43J/alternatives.json"},"ai":{"faq":[{"question":"What are the key ratings for this servo system?","answer":"Rated output is 0.4 kW at 3000 r/min, rated current 2.8 A, maximum current 7.8 A, and maximum torque 3.8 N·m."},{"question":"Does the motor include an oil seal?","answer":"Yes, the J designation in HG-KN43J indicates the motor is equipped with an oil seal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/mitsubishi/MR-JE-40A~3HG-KN43J","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/mitsubishi/MR-JE-40A~3HG-KN43J when reusing this data.
