It is paired with the LXM52 or LXM62 servo drive platforms and carries a single-turn SinCos Hiperface encoder on the non-drive end, which means absolute position feedback to the drive on power-up without a homing move — relevant for safety-rated machinery where the controller must know rotor angle before enabling motion. ## Torque envelope and holding brake Peak stall torque reaches 330 N.m with 124.5 A Irms available for acceleration peaks, so the dynamic reserve is roughly 5× continuous — the headroom that lets the drive push hard into a short move without saturating the current loop. The integrated holding brake pulls in at 25 W, which is the 24 VDC coil load the drive's brake output must switch; for vertical axes the brake releases only when the drive commands torque, so a brake-supply drop faults the axis down safely. ## Power, speed and rotor inertia Continuous power is 9.56 kW and nominal output power is 7.75 W at the 400/480 V drive rails — the nominal figure is the per-speed mechanical point the catalog benchmarks against, while 9.56 kW is the thermal ceiling the winding can sustain at the rated 9560 W continuous dissipation. ## Shaft, feedback and mechanical integration The 38 mm parallel-key shaft protrudes 80 mm with a 10 mm key width — the standard coupling and gearbox mounting profile for this frame, no second-shaft extension on the encoder side so the feedback housing stays compact inside the machine envelope. Maximum radial load is 3300 N at 1000 rpm, falling to 3100 N at 4000 rpm — the bearing-load derating curve a belt or pinion drive must respect, because over-speeding the shaft derates the load the front bearing can carry without fatigue. The motor flange is 180 mm centring collar with 14 mm mounting holes and 4 mm collar depth, and the electrical connection uses rotatable right-angled connectors — the rotatable head lets the wireman dress the cable to the cabinet gland without a 90° adapter. ## Sealing, cooling and duty cycle IP65 at the housing standard means the body withstands low-pressure washdown and dust ingress — adequate for food-and-bev conveyor zones, paint-line booths, and outdoor machinery cabinets where splashing is expected, but not for sustained high-pressure or steam cleaning where IP67 or higher is the requirement. Cooling is natural convection, with copper-hot temperature rated to 135 °C — the motor frame dissipates the 9.56 kW continuous loss through its surface alone, so panel builders mounting it inside a sealed enclosure must budget for the additional heat load or the winding thermal sensor will trip the drive.","metaTitle":"MH31903P11F2200 Servo Motor, 60 N.m, IP65, Hiperface","metaDescription":"Schneider MH3 190 mm servo motor, 60 N.m holding torque, three-phase, IP65, single-turn Hiperface encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"MH31903P11F2200","Length":"14.5 in (368 mm)","Category":"US1PC5218359","Key width":"0.4 in (10 mm)","Shaft end":"Parallel key","description":"MH3 servomotor, 190mm, 3 stacks, keyed Shaft, SinCos Singleturn 128, Brake, angular, IP65","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":"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":null,"sourceUrl":"https://www.se.com/be/en/product/MH31903P11F2200/mh3-servomotor-190mm-3-stacks-keyed-shaft-sincos-singleturn-128-brake-angular-ip65/"},"ai":{"faq":[{"question":"What is the MH31903P11F2200's listed length on this component line?","answer":"Overall length is 14.5 in (368 mm).
