The torque constant is 0.488 N·m/A at 40 °C, and the back EMF constant is 33.9 V/krpm at 40 °C — these values define the current-to-torque relationship and the voltage rise with speed, critical for drive tuning and bus voltage headroom at 6000 rpm maximum mechanical speed. ## Encoder feedback and IP67 sealing for wet environments The 17-bit magnetic multi-turn encoder provides 131,072 points per turn absolute position feedback — no homing sequence needed after power loss, which reduces cycle time in multi-axis systems. IP67 rating means the motor body and shaft seal withstand washdown and dust ingress, making it suitable for food-and-beverage, pharmaceutical, and other wet-area lines where hose-down cleaning is routine. ## Mounting and mechanical interface The Asian standard 60 mm flange with four 5.5 mm mounting holes on a 70 mm bolt circle matches the common NEMA 23 frame pattern — it bolts directly to standard gearboxes and machine frames without adapter plates. Depth is 70.2 mm (excluding shaft), width 88 mm, height 60 mm — the compact envelope fits into tight machine cavities; the two-connector electrical interface (male/female) simplifies cable routing and replacement. ## No holding brake — application constraint This variant ships without a holding brake (: Without), so the load must be held by the drive's holding torque at standstill or by an external mechanical brake on vertical axes — factor this into the safety circuit design for Z-axis applications.","metaTitle":"Schneider Electric BEH18MD0433MA5C Lexium 18 Servo Motor","metaDescription":"Schneider Electric BEH18MD0433MA5C Lexium 18 servo motor, 400 W, 1.27 Nm nominal torque, 3000 rpm, IP67, magnetic multi-turn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Depth":"70.2 mm","Range":"Lexium 18","Width":"88 mm","title":"BEH18MD0433MA5C","Height":"60 mm","Length":"88 mm","Shaft end":"Parallel key","description":"Servo motor BEH18, Lexium 18, 400W, 220V, M60, 17bit, MAG MT","Encoder type":"Magnetic encoder","Shaft length":"30.0 mm","Feedback type":"17 bits magnetic multi turn encoder","Holding brake":"Without","Nominal speed":"3000 rpm, 220 V, single phase","Rotor inertia":"0.59 kg.cm²","Nominal torque":"1.27 N.m, 220 V","Shaft diameter":"14.0 mm","Torque constant":"0.488 N.m/A at 40 °C","lifecycle_stage":"current","Continuous power":"400 W","Mounting support":"Asian standard flange","Back emf constant":"33.9 V/krpm at 40 °C","Device short name":"BEH18","Motor flange size":"60 mm","Peak stall torque":"4.45 N.m, 220 V","Maximum current Irms":"at 0.4 kW, 220 V","Nominal output power":"400 W, 220 V","Electrical connection":"2 connectors male/female","Number of motor poles":"10","Maximum axial force Fa":"74 N","Continuous stall torque":"1.27 N.m, 220 V","IP degree of protection":"IP67","Maximum radial force Fr":"245 N","Continuous stall current":"2.6 A","Maximum mechanical speed":"6000.0 rpm","Network number of phases":"3","Number of mounting holes":"4","Maximum permanent current":"8.7 A","Product or component type":"Servo motor","Speed feedback resolution":"131072 points/turn","[Us] rated supply voltage":"220 V","Ambient air temperature for operation":"0...40 °C","Circle diameter of the mounting holes":"5.5 mm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/796df0f6be70a7e785345fa50f872e6e.pdf","sourceUrl":"https://www.se.com/th/en/product/BEH18MD0433MA5C/servo-motor-beh18-lexium-18-400w-220v-m60-17bit-mag-mt/"},"ai":{"faq":[{"question":"What is the nominal torque and speed of this motor?","answer":"Nominal torque is 1.27 N·m at 220 V, with a nominal speed of 3000 rpm.
