Continuous power reaches 3.73 kW at 400/480 V three-phase, with continuous stall torque of 18.5 Nm across the 115–480 V three-phase range — the 57.42 A maximum current and 16.83 A continuous stall current define the drive sizing envelope. ## Feedback and environmental sealing for production lines The multiturn SinCos Hiperface encoder provides absolute position feedback over multiple shaft revolutions — this eliminates the need for a homing sequence on power-up in applications like pick-and-place or rotary indexing tables. IP65 rating means the motor body and connector interface withstand washdown from hosed liquids and airborne dust — suitable for food processing, packaging, or machining lines where coolant spray is present. Rotatable right-angled connectors allow the cable exit orientation to be adjusted on-site by up to 270°, simplifying cable routing in tight panel-to-machine transitions without adding a junction box. ## Mechanical interface and mounting constraints The 140 mm flange (5.5 in) with four 11 mm mounting holes on a 130 mm centring collar and 3.5 mm centring collar depth matches the IEC standard flange pattern — the motor bolts directly to the machine frame without an adapter plate. Shaft diameter is 24 mm with a parallel key and 50 mm shaft length — the 2240 N maximum radial force at 1000 rpm drops to 1550 N at 3000 rpm, so bearing life at higher speeds depends on the belt or coupling preload. Overall length is 192 mm (7.6 in) without a brake — the natural convection cooling requires free air movement around the finned housing, so panel-mounting with less than 50 mm clearance on the non-drive end will derate the continuous torque. ## Electrical parameters for drive commissioning Stator resistance of 0.23 Ω and inductance of 2.99 mH give an electrical time constant of 13 ms — the drive's current loop gains must be tuned to this L/R ratio for stable torque control without overshoot. Back EMF constant of 70.7 V/krpm means at 3500 rpm the motor generates 247 V line-to-line — the drive DC bus voltage must exceed this peak plus the voltage drop across the stator resistance at full current to maintain field-oriented control. Peak stall torque of 55.5 Nm at 115–480 V three-phase provides the overload headroom for acceleration and deceleration — the 57.42 A maximum current is the limit the drive must supply during this transient. The motor ships as a single unit (package quantity of 1) with the international standard flange and rotatable connectors — the IP65 rating and Hiperface encoder are factory-configured and not field-upgradable.","metaTitle":"Schneider Electric MH31402P12A2200 Servo Motor, 3.73 kW","metaDescription":"Schneider Electric MH31402P12A2200 servo motor, 3.73 kW continuous power at 400/480 V three-phase, 16.34 Nm nominal torque, IP65, multiturn SinCos Hiperface","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"7.6 in (192 mm)","Category":"US1PC5218359","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","Encoder type":"Multiturn SinCos Hiperface","Second shaft":"Without second shaft end","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","Nominal speed":"1000 rpm LXM52 14.87 mA, 115 V, single phase 2000 rpm LXM52 13.13 mA, 230 V, single phase 3500 rpm LXM52 9.76 mA, 400 V, three phase 3500 rpm LXM52 9.76 mA, 480 V, three phase 1000 rpm LXM62 14.87 mA, 115 V, single phase 2000 rpm LXM62 13.13 mA, 230 V, single phase 3500 rpm LXM62 9.76 mA, 400 V, three phase 3500 rpm LXM62 9.76 mA, 480 V, three phase","Rotor inertia":"32 kg.cm²","Nominal torque":"144.62 lbf.in (16.34 N.m) LXM52 14.87 mA, 115 V, three phase 123.9 lbf.in (14.0 N.m) LXM52 13.13 mA, 230 V, single phase 90.01 lbf.in (10.17 N.m) LXM52 9.76 mA, 400 V, three phase 90.01 lbf.in (10.17 N.m) LXM52 9.76 mA, 480 V, three phase 144.62 lbf.in (16.34 N.m) LXM62 14.87 mA, 115 V, single phase 123.9 lbf.in (14.0 N.m) LXM62 13.13 mA, 230 V, single phase 90.01 lbf.in (10.17 N.m) LXM62 9.76 mA, 400 V, three phase 90.01 lbf.in (10.17 N.m) LXM62 9.76 mA, 480 V, three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.1 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"3730 W","Mounting Support":"International standard flange","Sizing reference":"MH31402P","Back emf constant":"70.7 V/krpm","Device short name":"MH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"491.2 lbf.in (55.5 N.m), 115...480 V, three phase","Stator inductance":"2.99 mH","Stator resistance":"0.23 Ohm","Maximum current Irms":"57.42 A","Nominal output power":"1.71 W, 115 V 2.93 W, 230 V 3.73 W, 400 V 3.73 W, 480 V","Centring collar depth":"0.1 in (3.5 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":"163.7 lbf.in (18.5 N.m), 115...480 V, three phase","IP Degree of Protection":"IP65 standard","Maximum radial force Fr":"2240 N 1000 rpm 1780 N 2000 rpm 1550 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"16.83 A","Maximum mechanical speed":"4000 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":"13 ms","Circle diameter of the mounting holes":"6.5 in (165 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/2c948f78779f2457a43577081445e09f.pdf","sourceUrl":"https://www.se.com/us/en/product/MH31402P12A2200/servo-motor-mh3-140-195nmkeymultino-brakeip65-ip673krpm/","alternativesUrl":"https://aoctrl.com/api/mcp/products/MH31402P12A2200/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous power rating of the MH31402P12A2200?","answer":"The continuous power is 3.73 kW at 400/480 V three-phase, with nominal torque of 10.17 Nm at those voltages.
