This is the sustained output you can count on for duty cycles that don't exceed the motor's thermal capacity under natural convection cooling. Peak stall torque hits 39.9 N·m for short-duration acceleration and deceleration events — the motor can deliver this for the thermal time constant of the winding, not continuously. The 29.8 A maximum RMS current sets the drive's peak current requirement. ## Single-turn SinCos Hiperface encoder — feedback resolution and tuning implications The single-turn SinCos Hiperface encoder provides absolute position within one mechanical revolution, with sinusoidal analog signals for high-resolution interpolation. This feedback type supports smooth low-speed operation and good velocity-loop bandwidth — the drive's interpolator extracts the fine position from the sine/cosine tracks, so the effective resolution depends on the drive's interpolation factor. The back EMF constant is 77.41 V/krpm, and the torque constant is 1.2 N·m/A at 120°C copper temperature. These two constants are linked by the motor's electrical design — the drive's current loop must supply the magnetizing current to overcome the stator inductance of 6.72 mH and stator resistance of 0.69 Ω before torque builds. Nominal speed depends on the drive voltage and phase configuration: 1000 rpm at 115 V single-phase, 2000 rpm at 230 V single-phase, and 3500 rpm at 400 V or 480 V three-phase. The maximum mechanical speed is 4000 rpm — overspeed protection in the drive should be set below this to avoid mechanical damage. ## IP65, 140 mm flange, natural convection — mounting and environmental fit The motor carries an IP65 protection rating, meaning the housing is dust-tight and protected against water jets from any direction. This suits washdown environments in food processing or packaging lines where the motor body sees hose-down cleaning — the rotatable right-angled connectors maintain the seal when oriented for the cable exit. The flange size is 140 mm (5.5 in) with four mounting holes on an 11 mm diameter, centring collar diameter 130 mm and depth 3.5 mm. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length — standard for this frame class. The motor is cooled by natural convection, so no external fan or coolant circuit is needed; ensure free airflow around the housing for the rated continuous torque. Maximum radial force on the shaft end is 1930 N at 1000 rpm, derating to 1530 N at 2000 rpm and 1340 N at 3000 rpm. This bearing load limit must be checked against the belt tension or coupling force in the application — exceeding it shortens bearing life. ## Active production — sourcing and lifecycle status This servo motor is sourced through independent distribution channels.","metaTitle":"Schneider Electric MH31401P16A2200 Servo Motor, 2640 W","metaDescription":"Schneider Electric MH31401P16A2200 servo motor, 2640 W continuous power, 10.3 N·m stall torque, IP65, single-turn SinCos Hiperface encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"6.0 in (152 mm)","Category":"US1PC5218359","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","Encoder type":"Single turn SinCos Hiperface","Second shaft":"Without second shaft end","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","Nominal speed":"1000 rpm LXM52 7.82 mA, 115 V, single phase 2000 rpm LXM52 7.3 mA, 230 V, single phase 3500 rpm LXM52 6.35 mA, 400 V, three phase 3500 rpm LXM52 6.35 mA, 480 V, three phase 1000 rpm LXM62 7.82 mA, 115 V, single phase 2000 rpm LXM62 7.3 mA, 230 V, single phase 3500 rpm LXM62 6.35 mA, 400 V, three phase 3500 rpm LXM62 6.35 mA, 480 V, three phase","Rotor inertia":"16.46 kg.cm²","Nominal torque":"82.84 lbf.in (9.36 N.m) LXM52 7.82 mA, 115 V, three phase 75.2 lbf.in (8.5 N.m) LXM52 7.3 mA, 230 V, single phase 63.90 lbf.in (7.22 N.m) LXM52 6.35 mA, 400 V, three phase 63.90 lbf.in (7.22 N.m) LXM52 6.35 mA, 480 V, three phase 82.84 lbf.in (9.36 N.m) LXM62 7.82 mA, 115 V, single phase 75.2 lbf.in (8.5 N.m) LXM62 7.3 mA, 230 V, single phase 63.90 lbf.in (7.22 N.m) LXM62 6.35 mA, 400 V, three phase 63.90 lbf.in (7.22 N.m) LXM62 6.35 mA, 480 V, three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.2 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"2640 W","Mounting Support":"International standard flange","Sizing reference":"MH31401P","Back emf constant":"77.41 V/krpm","Device short name":"MH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"353.1 lbf.in (39.9 N.m), 115...480 V, three phase","Stator inductance":"6.72 mH","Stator resistance":"0.69 Ohm","Maximum current Irms":"29.8 A","Nominal output power":"0.98 W, 115 V 1.78 W, 230 V 2.64 W, 400 V 2.64 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":"91.2 lbf.in (10.3 N.m), 115...480 V, three phase","IP Degree of Protection":"IP65 standard","Maximum radial force Fr":"1930 N 1000 rpm 1530 N 2000 rpm 1340 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"8.58 A","Maximum mechanical speed":"4000 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":"9.7 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/d487b2f6907567720685a3b541b9632b.pdf","sourceUrl":"https://www.se.com/us/en/product/MH31401P16A2200/servo-motor-mh3-140-111nmkeysingle-16-linesno-brakeip65-ip673krpm/","alternativesUrl":"https://aoctrl.com/api/mcp/products/MH31401P16A2200/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous stall torque and peak torque of the MH31401P16A2200?","answer":"The continuous stall torque is 10.3 N·m across the 115–480 V three-phase range.
