That 12.6 N.m is the continuous stall torque as well — the motor can hold this torque indefinitely at standstill without overheating, which matters for indexing or clamping applications where the load stays under tension at zero speed. Peak stall torque reaches 37.8 N.m at 380 V three-phase — this is the short-term acceleration limit for rapid moves or breaking away from a stuck load. The drive must supply the maximum current of 38.88 A at 4 kW to hit that peak; confirm the drive's peak current rating matches this transient demand. Nominal speed is 3000 rpm at 380 V, with a maximum mechanical speed also 3000 rpm — the motor is not designed for overspeed operation above this ceiling. The 10-pole rotor keeps torque ripple low across the speed range. The integrated holding brake delivers 16 N.m holding torque — enough to secure a vertical load on a gantry or lift axis when power is removed. This brake is spring-applied, power-released; it engages on power loss or drive disable, so no external brake resistor or holding circuit is needed for the stop condition. Feedback comes from a 17-bit magnetic multi-turn encoder. The multi-turn absolute count tracks position across 2^17 revolutions without a battery — the magnetic sensing keeps the position on power cycle, which eliminates the homing sequence on startup for rotary or linear axes with limited travel. The torque constant is 0.9722 N.m/A at 40 °C. For a given load torque, divide by this constant to get the required motor current — at 12.6 N.m nominal, the drive must supply about 13 A continuous. The back EMF constant of 67.87 V/krpm at 40 °C sets the voltage the drive sees from the motor at speed; at 3000 rpm, the back EMF is roughly 204 V line-to-line. ## IP67 and flange dimensions — integration into a washdown or wet line IP67 protection on the motor body means it withstands temporary immersion and high-pressure washdown — suitable for food-and-beverage, pharmaceutical, or outdoor conveyor lines where hose-down cleaning is routine. The shaft seal and connector O-rings are the wet-end barriers; the IP rating applies when the mating connectors are properly seated. The motor mounts on an Asian standard flange with a 130 mm flange size and 9 mm mounting holes. Overall dimensions are 261.9 mm depth (motor body length plus shaft), 130 mm width, and 174.5 mm height — plan the panel or machine envelope around these, accounting for the cable bend radius at the connector exit. The part is a standard catalog item in the Lexium 18 family, so lead times are typically consistent with Schneider's production cycle.","metaTitle":"Schneider Electric BEH18LM4033MF6D Lexium 18 Servo Motor","metaDescription":"Schneider Electric BEH18LM4033MF6D Lexium 18 servo motor with brake, 4 kW continuous power, 12.6 N.m nominal torque at 380 V three-phase, IP67, 17-bit magnetic","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Depth":"261.9 mm","Range":"Lexium 18","Width":"130 mm","title":"BEH18LM4033MF6D","Height":"174.5 mm","Length":"261.9 mm","Inertia":"11.04 kg.cm²","Key width":"8 mm","Shaft end":"Parallel key","description":"BEH18 servo motor, Lexium 18, 380V,4.0kW,L130,17bit MAG MT,brake","Encoder type":"Magnetic encoder","Second shaft":"Without second shaft end","Shaft length":"63 mm","Feedback type":"17 bits magnetic multi turn encoder","Holding brake":"With","Nominal speed":"3000 rpm, 380 V, three phase","Rotor inertia":"11.04 kg.cm²","Holding torque":"16 N.m","Nominal torque":"12.6 N.m, 380 V, three phase","Product weight":"14.7 kg","Shaft diameter":"28 mm","Torque constant":"0.9722 N.m/A at 40 °C","Type of cooling":"Air-cooled","lifecycle_stage":"current","Continuous power":"4000 W","Mounting support":"Asian standard flange","Back emf constant":"67.87 V/krpm at 40 °C","Device short name":"BEH18","Motor flange size":"130 mm","Peak stall torque":"37.8 N.m, 380 V, three phase","Maximum current Irms":"38.88 A at 4 kW, 380 V","Nominal output power":"4000 W, 380 V, three phase","Electrical connection":"2 connectors male/female","Number of motor poles":"10","Maximum axial force Fa":"196 N","Continuous stall torque":"12.6 N.m, 380 V, three phase","IP degree of protection":"IP67","Maximum radial force Fr":"686 N","Mounting holes diameter":"9 mm","Continuous stall current":"12.96 A","Maximum mechanical speed":"3000 rpm","Network number of phases":"Three phase","Number of mounting holes":"4","Maximum permanent current":"38.88 A","Product or component type":"Servo motor","Speed feedback resolution":"131072 points/turn","[Us] rated supply voltage":"380 V","Ambient air temperature for operation":"0...40 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/1cb0d757cb22fbf4e29ec9c742f16938.pdf","sourceUrl":"https://www.se.com/th/en/product/BEH18LM4033MF6D/beh18-servo-motor-lexium-18-380v4-0kwl13017bit-mag-mtbrake/"},"ai":{"faq":[{"question":"What is BEH18LM4033MF6D's listed depth?","answer":"The depth is 261.9 mm, measured from the mounting flange face to the rear of the motor body including the shaft extension."},{"question":"What compliance documentation does Schneider Electric provide for BEH18LM4033MF6D?","answer":"The motor carries IP67 protection and is designed for three-phase 380 V operation.
