At nominal, the same 327.5 lbf.in (37 N.m) point holds whether the drive is an LXM52 or LXM62 on 400 V or 480 V three-phase (cites:), which means the BOM position is interchangeable across the two drive families without a torque derate. ## Mechanical fit on the machine Mounting is the international standard flange pattern (cites:) on a 7.5 in (190 mm) bolt circle (cites:), with four 0.6 in (14 mm) mounting holes (cites:,) and a 7.09 in (180 mm) centring collar seated 0.2 in (4 mm) deep (cites:,). Shaft end is a parallel-key 1.5 in (38 mm) diameter by 3.1 in (80 mm) long with a 0.4 in (10 mm) key (cites:,) — a standard coupling and gearbox input that does not require a custom-machined adapter. Radial load handling drops from 3300 N at 1000 rpm to 3100 N at 4000 rpm on the catalogue curve (cites:), and the maximum mechanical speed ceiling is 3800 rpm (cites:) — for a belt or pinion drive the buyer is choosing between shaft speed and overhung load, not treating them independently. Overall length is 12.2 in (310 mm) (cites:), so cabinet depth and the cable-bend radius behind the motor both need to be checked before commit. ## Feedback, brake, and electrical connection Feedback is a single-turn SinCos Hiperface encoder (cites:), the resolver-free digital protocol that the Lexium 52 and Lexium 62 drives accept directly — no add-on encoder card needed in the cabinet. There is no holding brake on this build (cites:) and no second shaft end (cites:), so vertical-axis applications that need a fail-safe brake must add it externally or pick the braked variant of the MH31903P sizing reference. Power and signal land on rotatable right-angled connectors (cites:), which lets the wireman orient the cable exit after the motor is bolted down instead of fighting the gland during mounting. ## Thermal envelope and sealing for plant duty Sealing is IP65 standard (cites:), which covers dust-tight and low-pressure water-jet exposure — appropriate for typical plant floors and most washdown-adjacent areas, though it is not the IP67K rating called for on direct food-zone spray-down. Continuous power at nominal is listed at 9560 W (cites:); the same row also lists 7.75 W as a 'nominal output power' entry (cites:), which is a data-entry artefact rather than a usable figure — the 9560 W continuous power entry is the rating that drives the cooling and cabinet-sizing decision. ## Sourcing posture for the BOM line No official second source or successor cross-reference is on file for this code, which is normal for a configured servo motor — the variant suffix fixes the encoder, brake option, shaft, and connector combination, so a 'replacement' must match all of those fields, not just the torque rating.","metaTitle":"MH31903P16A2200 Servo Motor, 37 N.m, IP65, 400/480 V","metaDescription":"Schneider MH31903P16A2200 three-phase servo motor, 37 N.m nominal, 65 N.m continuous stall, 330 N.m peak, SinCos Hiperface feedback, IP65, 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":"12.2 in (310 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":"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/us/en/product/MH31903P16A2200/servo-motor-mh3-190-944nmkeysingle-16-linesno-brakeip65-ip672krpm/","alternativesUrl":"https://aoctrl.com/api/mcp/products/MH31903P16A2200/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MH31903P16A2200 in this component family?","answer":"Within the MH3 family the natural adjacent positions are the other MH31903P variants that share the same 190 mm flange (cites:) and 37 N.m nominal torque (cites:) but differ on options such as holding brake (cites:) or second shaft end (cites:)."},{"question":"What IP rating does the MH31903P16A2200 carry?","answer":"Sealing is IP65 standard (cites:), which covers dust-tight duty and low-pressure water-jet exposure on typical plant floors.
