It carries a 23-bit optic multi-turn encoder for absolute position feedback — the resolution supports high-precision positioning without a homing cycle on power-up, which is the deciding factor for pick-and-place or indexing applications where the machine must resume from the last known position after a power loss. The IP67 rating means the motor body and connector interface are sealed against washdown and airborne particulates — suitable for food processing, packaging, or machine-tool coolant environments where ingress protection matters more than the IP54 typical of general-purpose servos. ## Physical fit and mounting constraints The motor uses an Asian standard flange with a 130 mm flange size and four mounting holes — this is the common NEMA 130 frame pattern used across Asian-built machine tools and packaging equipment, not the European 100 mm or 140 mm flange. Overall depth is 174.5 mm, width 136.6 mm, height 130 mm, and the shaft is 22.0 mm diameter with a 58.0 mm length and an 8.0 mm parallel key — the shaft dimensions dictate the coupling or pulley bore; a 22 mm bore with a 8 mm keyway is a standard metric fit. ## Torque, current, and thermal limits Continuous stall torque is 4.77 Nm at a continuous stall current of 2.8 A — this is the thermal limit for continuous duty; the motor can hold this torque indefinitely without overheating at rated cooling. Peak stall torque reaches 14.31 Nm at a maximum permanent current of 8.39 A — the 3:1 peak-to-continuous ratio is typical for a servo motor and covers acceleration and deceleration transients, but the RMS current over the duty cycle must stay below 2.8 A to avoid winding temperature rise beyond the insulation class. ## Electrical interface and feedback The motor uses two connectors (male/female) for power and feedback — the 23-bit optic multi-turn encoder communicates absolute position over a serial protocol (typically EnDat or BiSS, depending on the drive); the drive must support the same encoder protocol to read the multi-turn count. Torque constant is 1.704 Nm/A at 40 °C, and the back EMF constant is 108.1 V/krpm at 40 °C — these values let the drive calculate the current needed for a given torque and the voltage needed to overcome the back EMF at speed. At 3000 rpm maximum mechanical speed, the back EMF reaches about 324 V, which is within the 380 V DC bus of a standard drive. Maximum axial force is 196 N and maximum radial force is 686 N — these are the bearing load limits. A belt drive or direct coupling must not exceed the radial force at the shaft centre; an overhung load from a timing pulley will apply radial force that must be calculated from the belt tension. Volume pricing is available for project builds or MRO spares — quote request required. No official successor or cross-reference is recorded — the part is the current offering, not a legacy or replacement item.","metaTitle":"Schneider Electric BEH18MM1023CA6D Servo Motor, 1 kW","metaDescription":"Schneider Electric BEH18MM1023CA6D Lexium 18 servo motor, 1 kW nominal power, 2000 rpm, 4.77 Nm torque, IP67, 23-bit optic encoder.","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":"136.6 mm","title":"BEH18MM1023CA6D","Height":"130 mm","Length":"136.6 mm","Key width":"8.0 mm","Shaft end":"Parallel key","description":"Servo motor BEH18, Lexium 18, 1.0kW, 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":"13.62 kg.cm²","Nominal torque":"4.77 N.m, 380 V, three phase","Product weight":"5.9 kg","Shaft diameter":"22.0 mm","Torque constant":"1.704 N.m/A at 40 °C","Type of cooling":"Air-cooled","lifecycle_stage":"current","Continuous power":"1000 W","Mounting support":"Asian standard flange","Back emf constant":"108.1 V/krpm at 40 °C","Device short name":"BEH18","Motor flange size":"130 mm","Peak stall torque":"14.31 N.m, 380 V, three phase","Maximum current Irms":"8.39 A at 1.0 kW, 380 V","Nominal output power":"1000 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","Continuous stall current":"2.8 A","Maximum mechanical speed":"3000.0 rpm","Network number of phases":"3","Number of mounting holes":"4","Maximum permanent current":"8.39 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/8af4053c2990709a3947b12116d62200.pdf","sourceUrl":"https://www.se.com/th/en/product/BEH18MM1023CA6D/servo-motor-beh18-lexium-18-1-0kw-380v-m130-23bit-opt-mt/"},"ai":{"faq":[{"question":"What is the BEH18MM1023CA6D's depth and flange size?","answer":"The motor depth is 174.5 mm with a 130 mm Asian standard flange.
