The continuous stall current of 12.96 A and maximum current of 38.88 A at 4 kW define the drive sizing envelope — match the drive's continuous and peak current ratings to these numbers, not the nominal. ## 23-bit optic multi-turn encoder — position loop resolution The 23-bit optic multi-turn encoder gives 8,388,608 counts per revolution absolute position. At 3000 rpm the encoder output frequency sits around 419 MHz — well within the range of modern motion controllers, but the cable length and shielding matter for signal integrity. The feedback resolution supports velocity loop bandwidths above 100 Hz on a well-tuned system. Back EMF constant is 67.87 V/krpm at 40 °C; torque constant is 0.9722 N.m/A at the same temperature. These two numbers let you calculate the drive's required DC bus voltage for a given speed and the current loop gain for torque control. The IP67 rating on the housing means this motor survives washdown environments — the encoder connector and power connector seals are the critical path. ## Asian standard flange, without holding brake The 130 mm Asian standard flange with 9 mm mounting holes and four-hole pattern matches the common B5 / FF130 interface used across many Asian-sourced machine frames. No holding brake is fitted — this motor relies on the drive's holding torque at standstill or an external brake. If the application requires vertical-axis holding, an external spring-applied brake on the shaft or a separate brake motor is needed.","metaTitle":"Schneider Electric BEH18LM4033CA6D Lexium 18 Servo Motor","metaDescription":"Schneider Electric BEH18LM4033CA6D servo motor, Lexium 18 range, 4 kW continuous power, 12.6 N.m nominal torque at 3000 rpm, 23-bit optic multi-turn encoder","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Depth":"230.9 mm","Range":"Lexium 18","Width":"130 mm","title":"BEH18LM4033CA6D","Height":"174.5 mm","Length":"230.9 mm","Inertia":"10.1 kg.cm²","Key width":"8 mm","Shaft end":"Parallel key","description":"BEH18 servo motor, Lexium 18, 380V,4.0kW,L130,23bit, OPT MT","Encoder type":"Optic encoder","Second shaft":"Without second shaft end","Shaft length":"63 mm","Feedback type":"23 bits optic multi turn encoder","Holding brake":"Without","Nominal speed":"3000 rpm, 380 V, three phase","Rotor inertia":"10.1 kg.cm²","Nominal torque":"12.6 N.m, 380 V, three phase","Product weight":"13 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/20a75884a5befd49f67b57aafbb90721.pdf","sourceUrl":"https://www.se.com/th/en/product/BEH18LM4033CA6D/beh18-servo-motor-lexium-18-380v4-0kwl13023bit-opt-mt/"},"ai":{"faq":[{"question":"What does the 23-bit optic multi-turn encoder mean for positioning accuracy?","answer":"23-bit resolution means 8,388,608 absolute positions per revolution.
