Peak stall torque reaches 21.48 Nm — useful for acceleration transients, but the drive must limit the RMS current to stay within the continuous stall current of 4.27 A. Maximum mechanical speed is 3000 rpm, so the nominal 2000 rpm operating point leaves headroom for field weakening or high-speed cycles. The 10-pole motor design keeps the torque ripple low across the speed range. ## Feedback resolution and loop tuning The 23-bit optic multi-turn encoder gives 8,388,608 counts per revolution — enough resolution for sub-arc-minute positioning and smooth velocity control down to single-digit rpm. The optic encoder type is less susceptible to magnetic interference than a resolver, but the glass disc means shock and vibration limits matter during installation. ## Motor constants for the drive engineer Torque constant Kt is 1.677 N·m/A at 40 °C, and the back-EMF constant Ke is 110.2 V/krpm at 40 °C. These numbers let the drive calculate the current needed for a given torque and the voltage required to reach speed — expect the drive's DC bus to need at least 380 VDC to spin at 2000 rpm against the back-EMF. Maximum continuous current (Irms) is 12.8 A at 1.5 kW, 380 V. The continuous stall current is lower at 4.27 A — the difference reflects the cooling airflow at speed vs. stalled conditions. Air-cooled, so forced ventilation from the driven load or an external fan helps at low speeds. ## Bearing loads and mechanical interface Maximum radial force Fr is 686 N, maximum axial force Fa is 196 N. These are the static load limits at the shaft shoulder — belt drives or direct couplings must stay within these to avoid bearing brinelling. The parallel key transmits torque; no holding brake is fitted on this variant, so the load must be held by the drive's holding brake or an external mechanical brake.","metaTitle":"Schneider Electric BEH18MM1523CA6D Servo Motor, 1.5 kW","metaDescription":"BEH18MM1523CA6D Schneider Electric Lexium 18 servo motor, 1.5 kW, 7.16 Nm nominal torque, 2000 rpm, 23-bit optic encoder, IP67, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Depth":"174.5 mm","Range":"Lexium 18","Width":"152.6 mm","title":"BEH18MM1523CA6D","Height":"130 mm","Length":"152.6 mm","Key width":"8.0 mm","Shaft end":"Parallel key","description":"Servo motor BEH18, Lexium 18, 1.5kW, 380V, M130, 23bit, OPT MT","Encoder type":"Optic encoder","Second shaft":"Without second shaft end","Shaft length":"58.0 mm","Feedback type":"23 bits optic multi turn encoder","Holding brake":"Without","Nominal speed":"2000 rpm, 380 V, three phase","Rotor inertia":"19.95 kg.cm²","Nominal torque":"7.16 N.m, 380 V, three phase","Product weight":"7.4 kg","Shaft diameter":"22.0 mm","Torque constant":"1.677 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":"110.2 V/krpm at 40 °C","Device short name":"BEH18","Motor flange size":"130 mm","Peak stall torque":"21.48 N.m, 380 V, three phase","Maximum current Irms":"12.8 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":"7.16 N.m, 380 V, three phase","IP degree of protection":"IP67","Maximum radial force Fr":"686 N","Continuous stall current":"4.27 A","Maximum mechanical speed":"3000.0 rpm","Network number of phases":"3","Number of mounting holes":"4","Maximum permanent current":"12.8 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","Circle diameter of the mounting holes":"9 mm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/083fd5c5544801fcf32e91413514b6ba.pdf","sourceUrl":"https://www.se.com/th/en/product/BEH18MM1523CA6D/servo-motor-beh18-lexium-18-1-5kw-380v-m130-23bit-opt-mt/"},"ai":{"faq":[{"question":"What compliance documentation does Schneider provide for BEH18MM1523CA6D?","answer":"The evidence does not list specific compliance certificates (RoHS, REACH, UL, IEC) for this order code.
