IP65 standard rating covers splash and dust ingress in a typical factory cell; if the line runs washdown, plan a derating or an enclosure. Four 14 mm mounting holes on a 180 mm centring collar seat it against a standard IEC flange, and the published radial-load table — 3300 N at 1000 rpm down to 3100 N at 4000 rpm — confirms the bearing life budget for belt- or pinion-driven couplings at the high end of the speed range. ## Lifecycle read and sourcing posture Lifecycle stage is recorded as current on the MH3 line, with no official successor flagged for this specific code. The motor ships as a single-unit package without a holding brake or second shaft end, which matches the standard catalogue configuration rather than a custom build. For a drop-ship order the spread lives in the supplier's ability to ship clean every time — a 190 mm-frame servo with a Hiperface encoder needs the cable set and connector orientation matched to the BOM line before the box goes out.","metaTitle":"Schneider MH31903P02A2200 Servo Motor, 37 N.m, 2000 rpm","metaDescription":"Schneider MH3 servo motor, 37 N.m nominal torque at 2000 rpm with LXM52/LXM62 drives, Multiturn SinCos Hiperface encoder, IP65 flange.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"12.2 in (310 mm)","Category":"US1PC5218359","Shaft end":"Smooth shaft","Encoder type":"Multiturn SinCos Hiperface","Second shaft":"Without second shaft end","Shaft length":"3.1 in (80 mm)","Holding brake":"Without","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":"194.1 kg.cm²","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","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":"128 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/MH31903P02A2200/mh3-servomotor-190mm-3-stacks-smooth-shaft-sincos-multiturn-128-no-brake-angular-ip65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/MH31903P02A2200/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy MH31903P02A2200 and how do I get a price?","answer":"Independent distribution carries the MH31903P02A2200 against purchase orders rather than shelf stock — request an RFQ with the BOM quantity, drive pairing (LXM52 or LXM62), and connector orientation.
