The built-in electromagnet brake holds the load when power is removed — essential for vertical-axis stages, Z-axis robot arms, or any application where the load must not drift on power loss. The oil seal (J suffix) protects the shaft output from lubricant ingress in gearbox-coupled installations. Rated current draws 5.6 A continuous, with a 17 A peak for acceleration and deceleration transients. The power rate at continuous rated torque is 16.5 kW/s — a measure of how quickly the motor can accelerate a load, directly affecting cycle time in pick-and-place or indexing moves. ## IP67 enclosure and ambient limits for machine integration The motor is totally enclosed, naturally cooled, and rated IP67 — the housing and shaft seal resist dust ingress and temporary immersion, making it suitable for washdown zones, food processing lines, or outdoor cabinet installations where coolant mist or wash spray is present. No fan means no additional noise or filter maintenance, but the 40 °C upper ambient limit must be respected; above that, torque derating applies. Vibration rank V10 and vibration resistance of 24.5 m/s² in X and Y axes confirm the motor can tolerate the shock and vibration typical of machine-tool spindles and conveyor drives without bearing or encoder degradation. The altitude limit of 2000 m means above that elevation, the thinner air reduces natural convection cooling — factor in derating for high-altitude installations. ## Inertia matching and tuning constraints The recommended load-to-motor inertia ratio is 15 times or less. Exceeding this ratio makes the servo loop harder to stabilize — the proportional and integral gains must be reduced, which lengthens settling time and can cause overshoot or oscillation on position moves. For high-ratio loads (e.g., a large rotary table driven through a reduction gear), a larger-frame motor or a two-inertia notch filter in the drive is needed. Insulation class 155 (F) means the winding insulation withstands a 155 °C hot-spot temperature — adequate for the 40 °C ambient plus the internal temperature rise from continuous rated current. The IP67 sealing also traps heat; ensure the mounting surface or any auxiliary cooling (if used) keeps the winding temperature within the F-class limit during peak torque moves.","metaTitle":"Mitsubishi HG-SN102BJ-S100 Servo Motor with Brake, 1.0 kW","metaDescription":"Mitsubishi HG-SN102BJ-S100 servo motor, 1.0 kW rated output, 4.77 N·m torque, 2000 r/min base speed, IP67, with holding brake and oil seal.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors with Brake"],"specifications":{"title":"HG-SN102BJ-S100","Weight":"8.2 Kg","Altitude":"max 2000m or less above sea level","Ambience":"Indoors (no direct sunlight), free from corrosive gas, flammable gas, oil mist, dust, and dirt","Structure":"Totally enclosed, natural cooling (IP rating: IP67)","Environment":"Ambient temperature : Operation: 0 °C to 40 °C (non-freezing), storage: -15 °C to 70 °C (non-freezing) Ambient humidity Operation : 10 %RH to 80 %RH (non-condensing), storage: 10 %RH to 90 %RH (non-condensing) Ambience : Indoors (no direct sunlight), free from corrosive gas, flammable gas, oil mist, dust, and dirt Altitude : max 2000m or less above sea level Vibration resistance : X, Y: 24.5 m/s2","Product No.":"HG-SN102BJ-S100","description":"Servo Motor","Product Type":"Servo Motor","Specifications":"Rated output [kW] : 1.0 Rated torque [N•m] : 4.77 Rated speed [r/min] : 2000 Maximum speed [r/min] : 3000 Instantaneous permissible speed [r/min] : 3450 Rated current [A] : 5.6 Maximum current [A] : 17 Power Rate at Continuous Rated Torque [kW/s] : 16.5 Recommended load to motor inertia ratio : 15 times or less Insulation class : 155 (F) Structure : Totally enclosed, natural cooling (IP rating: IP67) Vibration rank : V10","Vibration rank":"V10","Shipping Weight":"10 Kg","lifecycle_stage":"current","Insulation class":"155 (F)","Model Designation":"HG-SN = Series 10 = Rated output [1.0 kW] 2 = Rated speed [2000 r/min] B = With Electromagnet Brake J = Oil seal Installed","Rated current [A]":"5.6","Rated output [kW]":"1.0","Ambient temperature":"Operation: 0 °C to 40 °C (non-freezing), storage: -15 °C to 70 °C (non-freezing)","Estimated Lead Time":"Usually ships in 1-10 working days.","Maximum current [A]":"17","Rated speed [r/min]":"2000","Rated torque [N•m]":"4.77","Vibration resistance":"X, Y: 24.5 m/s2","Maximum speed [r/min]":"3000","Ambient humidity Operation":"10 %RH to 80 %RH (non-condensing), storage: 10 %RH to 90 %RH (non-condensing)","Instantaneous permissible speed [r/min]":"3450","Recommended load to motor inertia ratio":"15 times or less","Power Rate at Continuous Rated Torque [kW/s]":"16.5"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$762.00","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/554195f435ff6c531999b74f64275095.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does the model designation HG-SN102BJ-S100 decode to?","answer":"HG-SN is the series. 10 = 1.0 kW rated output. 2 = 2000 r/min rated speed.
