IP65 ingress protection with rotatable right-angled connectors and natural convection cooling means the motor is specified for cabinet-adjacent or sealed-machine installations rather than open washdown; the encoder feedback is a multiturn SinCos Hiperface device, the bus-compatible interface that pairs directly with Lexium 52 and Lexium 62 drive families. ## 37 N.m nominal, 330 N.m peak — the torque envelope Peak stall torque reaches 330 N.m across 115…480 V three-phase, with continuous stall torque of 65 N.m at 36.1 A and a maximum Irms of 124.5 A; the peak figure governs short-cycle accel/decel bursts (indexed moves, press feeds, vertical-axis lifting under hold) while the continuous figure governs any dwell that holds the rotor loaded — read both before picking this motor for a continuous-torque application. ## Shaft, bearings, and the radial-load derating Mounting is via four 14 mm holes on the international-standard flange, with a 180 mm centring collar; the brake option is omitted (without holding brake, without second shaft end), so any vertical-axis application needs a mechanical brake on the gearbox or a second-source motor with the brake option from the same MH3 family.","metaTitle":"Schneider MH31903P17A2200 Servo Motor, 37 N.m, 310 mm","metaDescription":"Schneider MH31903P17A2200 three-phase servo motor, 37 N.m nominal, 38 mm shaft, Hiperface encoder, IP65.","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","Key width":"0.4 in (10 mm)","Shaft end":"Parallel key","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":"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/MH31903P17A2200/mh3-servomotor-190mm-3-stacks-keyed-shaft-sincos-multiturn-16-no-brake-angular-ip65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/MH31903P17A2200/alternatives.json"},"ai":{"faq":[{"question":"Who supplies the MH31903P17A2200 and how is it quoted for volume purchases?","answer":"Independent industrial-automation distribution handles this MH3 servo on a quoted-to-order basis against the BOM line.
