The continuous stall torque ceiling is 65 N.m, with a peak stall of 330 N.m for the acceleration transient — the gap between nominal and peak is what lets the motor survive indexing moves and emergency stops without stalling the drive (citing,). ## Hiperface feedback, rotatable connectors, IP65 Feedback is a single-turn SinCos Hiperface encoder — the absolute single-turn position the Lexium drive uses for commutation and torque control without a homing move at every power-up (citing). The connector exit is a rotatable right-angled plug, which lets the wireman orient the cable after the motor is bolted to the gearbox or coupling — useful in tight panels where a straight connector would not clear the structure (citing). IP65 on the standard housing covers dust and low-pressure water jets, so the motor survives washdown-adjacent zones on a food or pharma line when the cable gland is properly torqued (citing). ## Flange, shaft, and radial load Mounting is the international standard flange — 190 mm flange size with a 180 mm centring collar and four 14 mm mounting holes on the standard pattern, which bolts directly into a gearhead or a machine faceplate without an adapter plate (citing,). The smooth shaft is 38 mm diameter by 80 mm long, sized for the radial load envelope that drops from 3300 N at 1000 rpm to 3100 N at 4000 rpm — the right figure to check is the application speed, not the headline motor speed, because belt and gear radial load scales with rpm (citing,). Centring collar depth is 4 mm, so the pilot registers cleanly into the mating bore (citing). ## Electrical constants and drive matching Back-EMF constant is 129.2 V/krpm and torque constant is 1.8 N.m/A at the 120 °C copper-hot reference — these are the two numbers the drive sizing tool uses to land on the right continuous current, which sits at 36.1 A against a 124.5 A Irms maximum for short overload events (citing,). Maximum mechanical speed is 3800 rpm, so any application above that needs a gearbox or a different motor frame (citing).","metaTitle":"MH31903P01A2200 Servo Motor, 37 N.m, 2000 rpm, Hiperface","metaDescription":"Schneider MH31903P01A2200 servo motor, MH3 series, 37 N.m nominal torque at 2000 rpm, Hiperface feedback, IP65, quoted to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"MH31903P01A2200","Length":"12.2 in (310 mm)","Category":"US1PC5218359","Shaft end":"Smooth shaft","description":"servo motor MH3 190 94,4Nm,no key,single,no brake,IP65/IP67,2kRPM","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":"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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"{'url': 'https://www.se.com/us/en/product/download-pdf/MH31903P01A2200?filename=Schneider+Electric_Lexium-52-Motors_MH31903P01A2200.pdf', 'path_name': '7c53b8b9067afadb8269ea3c619ef4aa.pdf', 'path_url': 'https://s3.lax.sharktech.net/viassion/datasheets/schneider_electric/7c53b8b9067afadb8269ea3c619ef4aa.pdf', 'status': 1}","sourceUrl":"https://www.se.com/us/en/product/MH31903P01A2200/servo-motor-mh3-190-944nmno-keysingleno-brakeip65-ip672krpm/"},"ai":{"faq":[{"question":"What phase wiring does MH31903P01A2200 take?","answer":"Single-phase supply is not supported on this frame."},{"question":"How long is the MH31903P01A2200 motor body?","answer":"The motor body length is 12.2 in (310 mm) end-to-end at the standard mounting flange, so cabinet depth planning should budget at least that plus the connector bend radius for the rotatable right-angled plug (citing,)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/MH31903P01A2200","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/MH31903P01A2200 when reusing this data.
