It delivers 7.16 N.m nominal torque at 2000 rpm on a 380 V three-phase supply, with a peak stall torque of 21.48 N.m for short-duration acceleration loads. The 17-bit magnetic multi-turn encoder provides absolute position feedback over multiple shaft revolutions, eliminating the need for a home cycle on power-up in applications like pick-and-place, packaging, or material handling. ## Torque and thermal limits for sizing Continuous stall torque is 7.16 N.m at 4.27 A continuous stall current, with a torque constant of 1.677 N.m/A at 40 °C — this is the linear torque-per-amp figure for sizing the drive's current loop. The maximum permanent current is 12.8 A, which corresponds to the peak stall torque region; sustained operation above the continuous stall current requires duty-cycle derating to avoid winding overtemperature. The motor is air-cooled (self-ventilated) with no separate blower, so the duty cycle must account for natural convection in the enclosure. The back EMF constant of 110.2 V/krpm at 40 °C sets the voltage ceiling the drive must supply at top speed — at 3000 rpm the back EMF reaches about 330 V line-to-line, leaving headroom on a 380 V bus. ## Mounting and mechanical interface The motor uses an Asian standard flange with a 130 mm flange size and four mounting holes — common on machines built to Japanese or Chinese machine-tool standards. The shaft is 22.0 mm diameter with a parallel key (8.0 mm key width) and 58.0 mm shaft length, which mates with standard timing-belt pulleys or direct couplings in that bore range. Maximum radial force is 686 N and maximum axial force is 196 N — these are the bearing load limits for belt-drive or overhung-load applications. Exceed these and the bearing life drops fast; a coupling misalignment that pushes radial load past 686 N will show up as vibration before the bearing fails. The electrical connection uses two male/female connectors — one for power, one for feedback. No holding brake is fitted (: Without), so the load must be held by the drive's holding brake or an external mechanical brake when power is off.","metaTitle":"Schneider Electric BEH18MM1523MA6D Servo Motor, 1.5 kW","metaDescription":"Schneider Electric BEH18MM1523MA6D Lexium 18 servo motor, 1.5 kW continuous power, 2000 rpm nominal speed, IP67, 17-bit magnetic multi-turn 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":"152.6 mm","title":"BEH18MM1523MA6D","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, 17bit, MAG MT","Encoder type":"Magnetic encoder","Second shaft":"Without second shaft end","Shaft length":"58.0 mm","Feedback type":"17 bits magnetic 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":"131072 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/d0394cb035576760ee277806e7b3c209.pdf","sourceUrl":"https://www.se.com/th/en/product/BEH18MM1523MA6D/servo-motor-beh18-lexium-18-1-5kw-380v-m130-17bit-mag-mt/"},"ai":{"faq":[{"question":"What is the BEH18MM1523MA6D's IP rating and what does it mean for washdown environments?","answer":"The motor is rated IP67. This means the motor body and connector interface are dust-tight and protected against temporary immersion in water — suitable for washdown in food processing, beverage, or pharmaceutical lines where hose-down cleaning is standard. The connector O-ring is the wet-end seal, so the mating connector must also be IP67-rated to maintain the protection."},{"question":"Does the BEH18MM1523MA6D have a holding brake?","answer":"No. The holding brake field is marked 'Without'. The motor relies on the drive's holding brake function or an external mechanical brake to hold the load when power is removed. If your application requires a brake on the motor shaft, you need a different variant in the Lexium 18 family."},{"question":"What encoder feedback does the BEH18MM1523MA6D use?","answer":"It uses a 17-bit magnetic multi-turn encoder. The multi-turn capability tracks absolute position over multiple shaft revolutions, so the controller knows the exact position at power-up without a homing sequence. The magnetic sensing is tolerant to shock and vibration compared to optical encoders."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/BEH18MM1523MA6D","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/BEH18MM1523MA6D when reusing this data.
