The MH31903P16F2200 is a Schneider Electric MH3 series three-phase servo motor — a 190 mm flange, naturally cooled AC servo with a single-turn SinCos Hiperface encoder and an integrated holding brake, sized in the MH31903P frame and intended to mount onto a standard international flange. It is the rotor-and-feedback end of a Lexium 52 or Lexium 62 drive package: the nominal 2000 rpm point is reached on either drive at 21.3 mA control current on 400 V or 480 V three-phase rails. For panel builders and field-service techs, the IP65 rating on the body plus rotatable right-angled connectors means the motor can live close to the machine — under coolant splash, near gearbox housings, inside a food-and-bev washdown envelope — without a separate sealing enclosure. ## Torque envelope at 2000 rpm Holding torque is 60 N.m and the continuous stall torque is 65 N.m across 115 to 480 V three-phase — the winding holds the rated torque across the full Schneider drive voltage window. Nominal torque is 37 N.m at the 2000 rpm point on the Lexium 52 / Lexium 62 at 21.3 mA, so the working point sits at roughly two-thirds of the continuous torque envelope, leaving headroom for acceleration transients before the drive reaches current clamp. Peak stall torque for short-term dynamics — indexing moves, E-stop ramps — is 330 N.m; the drive must be rated to deliver the matching Irms of 124.5 A on those peaks. Continuous power reaches 9560 W with natural convection; the 135 °C copper-hot thermal ceiling is the derating anchor for hot-cabinet or motor-over-gearbox installations. ## Encoder, shaft, and brake — what the kit ships with Feedback is a single-turn SinCos Hiperface encoder, which gives absolute single-turn position over the Hiperface protocol — no batteries to replace, no homing routine on every power-up. The holding brake pulls in at 25 W; when the kit arrives, the brake is part of the motor assembly — no separate brake rectifier, no external coil driver, no missing accessory to chase down on install. ## Mounting readiness before the flange goes on Flange is 190 mm with a centring collar 180 mm diameter and 4 mm deep, drilled for 14 mm mounting hardware — dimensionally standard for the MH3 family, so a motor swap on an existing gearbox pad or faceplate lands without adapter plate machining. Radial load on the shaft is derated by speed: 3300 N at 1000 rpm falling to 3100 N at 4000 rpm, so a belt drive or pinion choice must respect the higher figure at lower speed rather than peak rpm. Cooling is natural convection only — no integrated fan, no liquid jacket — so the cabinet airflow around the motor body carries the 9560 W continuous dissipation; a blank plate or stuffed heat-sink upstream of the motor is the easiest way to overheat it.","metaTitle":"MH31903P16F2200 Servo Motor, 60 N.m, Three Phase","metaDescription":"Schneider Electric MH31903P16F2200 MH3 servo motor, three phase, 60 N.m holding torque, IP65, single-turn SinCos Hiperface encoder, quoted to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"14.5 in (368 mm)","Category":"US1PC5218359","Key width":"0.4 in (10 mm)","Shaft end":"Parallel key","Encoder type":"Single turn SinCos Hiperface","Second shaft":"Without second shaft end","Shaft length":"3.1 in (80 mm)","Holding brake":"With","Nominal speed":"2000 rpm LXM52 21.3 mA, 400 V, three phase 2000 rpm LXM52 21.3 mA, 480 V, three phase 2000 rpm LXM62 21.3 mA, 400 V, three phase 2000 rpm LXM62 21.3 mA, 480 V, three phase","Rotor inertia":"208.8 kg.cm²","Holding torque":"531.04 lbf.in (60 N.m)","Nominal torque":"327.5 lbf.in (37 N.m) LXM52 21.3 mA, 400 V, three phase 327.5 lbf.in (37 N.m) LXM52 21.3 mA, 480 V, three phase 327.5 lbf.in (37 N.m) LXM62 21.3 mA, 400 V, three phase 327.5 lbf.in (37 N.m) LXM62 21.3 mA, 480 V, three phase","Shaft diameter":"1.5 in (38 mm)","Torque constant":"1.8 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"9560 W","Mounting Support":"International standard flange","Sizing reference":"MH31903P","Back emf constant":"129.2 V/krpm","Device short name":"MH3","Motor flange size":"7.5 in (190 mm)","Peak stall torque":"2920.7 lbf.in (330 N.m), 115...480 V, three phase","Stator inductance":"3.62 mH","Stator resistance":"0.13 Ohm","Brake pull-in power":"25 W","Maximum current Irms":"124.5 A","Nominal output power":"7.75 W, 400 V 7.75 W, 480 V","Centring collar depth":"0.2 in (4 mm)","Electrical Connection":"Rotatable right-angled connectors","Nbr. of units in pkg.":"1","Number of motor poles":"10","Temperature copper hot":"275 °F (135 °C)","Continuous stall torque":"575.3 lbf.in (65 N.m), 115...480 V, three phase","IP Degree of Protection":"IP65 standard","Maximum radial force Fr":"3300 N 1000 rpm 3250 N 2000 rpm 3150 N 3000 rpm 3100 N 4000 rpm","Mounting holes diameter":"0.6 in (14 mm)","Centring collar diameter":"7.09 in (180 mm)","Continuous stall current":"36.1 A","Maximum mechanical speed":"3800 rpm","Number of mounting holes":"4","Product or Component Type":"Servo motor","Speed feedback resolution":"16 periods","[Us] rated supply voltage":"115...480 V","Stator electrical time constant":"21.6 ms","Circle diameter of the mounting holes":"8.5 in (215 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://www.se.com/ie/en/product/MH31903P16F2200/mh3-servomotor-190mm-3-stacks-keyed-shaft-sincos-singleturn-16-brake-angular-ip65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/MH31903P16F2200/alternatives.json"},"ai":{"faq":[{"question":"What is MH31903P16F2200's listed length on this component line?","answer":"The body length is 14.5 in (368 mm), with the 190 mm international-standard flange, 180 mm centring collar, and 80 mm shaft length making up the overall installation envelope."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/MH31903P16F2200","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/MH31903P16F2200 when reusing this data.
