That torque rating holds at the continuous stall condition too — same 12.6 Nm at zero speed, so the motor can hold position under load without overheating. Peak stall torque reaches 37.8 Nm at 380 V, with a maximum current draw of 38.88 A. The torque constant is 0.9722 Nm/A at 40 °C, which lets you estimate current draw for any torque demand below the peak. ## Brake and encoder — what holds and what tracks The integrated holding brake delivers 16 Nm holding torque — enough to secure a vertical axis or a conveyor load when power is removed. The motor ships with the brake engaged; the drive must release it before the first move. Feedback comes from a 23-bit optic multi-turn encoder. The multi-turn count tracks absolute position over multiple shaft revolutions, so the axis does not need a home cycle after a power loss — the drive reads the position directly at power-up. ## Mounting and environmental fit The motor uses an Asian standard flange with a 130 mm flange size and 9 mm mounting holes. The shaft is 28 mm diameter with a parallel key, 63 mm shaft length, and the key width is 8 mm. Overall dimensions: 130 mm wide, 174.5 mm tall, 261.9 mm deep. IP67 rating means the motor body and the connector interface are sealed against dust and temporary immersion — suitable for washdown environments in food processing or packaging lines. Cooling is air-cooled, so keep the fin area clear of debris.","metaTitle":"Schneider Electric BEH18LM4033CF6D Servo Motor, 4 kW","metaDescription":"Schneider Electric BEH18LM4033CF6D Lexium 18 servo motor with brake. 4 kW continuous power, 12.6 Nm nominal torque, 23-bit multi-turn encoder, IP67.","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":"BEH18LM4033CF6D","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,L130,23bit, OPT MT,brake","Encoder type":"Optic encoder","Second shaft":"Without second shaft end","Shaft length":"63 mm","Feedback type":"23 bits optic 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":"8388608 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/2281c608543a0fe03c1fb8281c3795a2.pdf","sourceUrl":"https://www.se.com/th/en/product/BEH18LM4033CF6D/beh18-servo-motor-lexium-18-380v4-0kwl13023bit-opt-mtbrake/"},"ai":{"faq":[{"question":"What is the holding torque of the brake on BEH18LM4033CF6D?","answer":"The integrated holding brake provides 16 Nm holding torque.
