That frame size fits the Lexium 18 footprint — plan for the motor body plus the connector overhang when laying out the machine baseplate. ## Torque and speed — matching the load to the motor's capability Rated 1.5 kW continuous output at 380 V three-phase, the motor delivers 4.77 N.m nominal torque at 3000 rpm. The continuous stall torque matches the nominal at 4.77 N.m — the thermal limit is the same whether turning or stalled, so the duty cycle determines how long you can hold torque at zero speed. Peak stall torque reaches 14.31 N.m — roughly 3× the continuous rating — for acceleration and short-duration overloads. The torque constant of 0.984 N.m/A at 40 °C means the drive current scales linearly with demanded torque; the maximum current of 14.58 A at 1.5 kW sets the drive's peak output requirement. The 10-pole rotor design gives a relatively low cogging torque profile, which helps smooth low-speed tracking. Maximum mechanical speed is 3000 rpm — the back EMF constant of 65.28 V/krpm at 40 °C means the drive's DC bus voltage must stay above the generated voltage at top speed to maintain current control. ## Encoder feedback — 17-bit magnetic multi-turn for absolute position retention The magnetic multi-turn encoder provides 17 bits of resolution per revolution, giving 131,072 counts per turn. Multi-turn tracking retains the absolute position over 4096 revolutions — no homing sequence needed after a power cycle if the shaft hasn't been turned past that range. Magnetic encoders are more tolerant of contamination than optical types — the IP67 rating on the motor body means the encoder cavity stays sealed against washdown and dust ingress. The two-connector electrical interface (male/female) carries power, feedback, and the brake wires in a single plug-and-play cable set. ## Holding brake — 8 N.m for vertical-axis safety The integrated holding brake delivers 8 N.m of holding torque — sufficient to hold the rated load on a vertical axis when power is removed. The brake is spring-applied, power-released: it engages on power loss or E-stop, so the load stays put without relying on the drive's holding current. ## Bearing loads and cooling — radial and axial force limits for direct coupling The motor bearings are rated for a maximum radial force of 686 N and a maximum axial force of 196 N. These limits govern belt-drive or overhung-load applications — a direct coupling with a flexible element usually stays well within both, but a belt tensioning force that exceeds the radial limit will shorten bearing life. Cooling is air-cooled (self-ventilated), not separately fan-forced. The continuous torque rating assumes free airflow around the motor body; mounting in a confined pocket or with thermal blankets will require derating.","metaTitle":"Schneider Electric BEH18LH1533MF6D Servo Motor, 1.5 kW","metaDescription":"Schneider Electric BEH18LH1533MF6D Lexium 18 servo motor with brake, 1.5 kW, 3000 rpm, 4.77 N.m nominal torque, 17-bit magnetic multi-turn encoder, IP67.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Depth":"176 mm","Range":"Lexium 18","Width":"100 mm","title":"BEH18LH1533MF6D","Height":"144.5 mm","Length":"176 mm","Inertia":"3.5 kg.cm²","Key width":"8 mm","Shaft end":"Parallel key","description":"BEH18 servo motor, Lexium 18, 380V,1.5kW,L100,17bit MAG MT,brake","Encoder type":"Magnetic encoder","Second shaft":"Without second shaft end","Shaft length":"45 mm","Feedback type":"17 bits magnetic multi turn encoder","Holding brake":"With","Nominal speed":"3000 rpm, 380 V, three phase","Rotor inertia":"3.5 kg.cm²","Holding torque":"8 N.m","Nominal torque":"4.77 N.m, 380 V, three phase","Product weight":"5.1 kg","Shaft diameter":"24 mm","Torque constant":"0.984 N.m/A at 40 °C","Type of cooling":"Air-cooled","lifecycle_stage":"current","Continuous power":"1500 W","Mounting support":"Asian standard flange","Back emf constant":"65.28 V/krpm at 40 °C","Device short name":"BEH18","Motor flange size":"100 mm","Peak stall torque":"14.31 N.m, 380 V, three phase","Maximum current Irms":"14.58 A at 1.5 kW, 380 V","Nominal output power":"1500 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":"4.77 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":"4.86 A","Maximum mechanical speed":"3000 rpm","Network number of phases":"Three phase","Number of mounting holes":"4","Maximum permanent current":"14.58 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/b4e52a812e311a5a4a3e541a212c2273.pdf","sourceUrl":"https://www.se.com/th/en/product/BEH18LH1533MF6D/beh18-servo-motor-lexium-18-380v1-5kwl10017bit-mag-mtbrake/"},"ai":{"faq":[{"question":"What is the BEH18LH1533MF6D's continuous power and torque rating?","answer":"Continuous output power is 1500 W at 380 V three-phase, with a nominal torque of 4.77 N.m at 3000 rpm.
