Nominal torque sits at 10.6 Nm at 400 V three-phase, dropping slightly to 10.4 Nm at 480 V three-phase due to flux weakening at higher bus voltage. Peak stall torque reaches 27 Nm, giving you a 2.4× overload margin for acceleration transients — enough to handle short-duration load spikes without tripping the drive. ## Encoder feedback and position retention The absolute multiturn SinCos Hiperface encoder retains position through power cycles — no homing routine on restart, which matters for pick-and-place or gantry applications where lost steps cost cycle time. Maximum mechanical speed is 4000 rpm, but the encoder's electrical bandwidth supports the full speed range without pulse dropout. ## Mounting and environmental fit The motor mounts on an international standard flange with a 140 mm flange size and a 130 mm centring collar — common for this power class, so it swaps into existing machine frames without adapter plates. IP54 as standard with the shaft bushing without seal ring; upgrade to IP65 by fitting the shaft seal ring — both conform to IEC 60034-5. The IP65 variant handles washdown environments; IP54 suits dry cabinet installations. Natural convection cooling means no fan — no debris ingestion, no fan noise, and one less failure point in dusty or food-grade lines. Electrical connection via a rotatable right-angled or straight connector — choose the orientation that keeps the cable bundle clear of moving parts on the machine frame. ## Mechanical interface and bearing load limits Shaft diameter is 24 mm with a parallel key and 50 mm shaft length — standard for coupling to timing pulleys or direct-drive loads via a bell housing. Maximum radial force Fr is 1930 N at 1000 rpm, dropping to 1340 N at 3000 rpm — derate the overhung load as speed increases to protect the bearing race. Maximum axial force Fa is 300 N — sufficient for helical-gear thrust but not for axial plunger loads; use a thrust bearing if the application exceeds this. The sizing reference SH31401M guides drive selection — pair it with a compatible Schneider servo drive rated for the continuous stall current of 4 A and peak current of 10.8 A.","metaTitle":"Schneider Electric SH31401M12A1000 Servo Motor, 1700 W","metaDescription":"Schneider Electric SH31401M12A1000 servo motor, 1700 W continuous power, 11 Nm nominal torque, absolute multiturn 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":"8.6 in (217.5 mm)","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","Nominal speed":"375 rpm 115 V single phase 750 rpm 230 V single phase 1500 rpm 400 V three phase 1800 rpm 480 V three phase","Rotor inertia":"7.41 kg.cm²","Nominal torque":"97.4 lbf.in (11 N.m) 115 V single phase 96.92 lbf.in (10.95 N.m) 230 V single phase 93.8 lbf.in (10.6 N.m) 400 V three phase 92.05 lbf.in (10.4 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"2.78 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"1700 W","Mounting Support":"International standard flange","Sizing reference":"SH31401M","Back emf constant":"193 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"239.0 lbf.in (27 N.m) 115...480 V three phase","Stator inductance":"88.55 mH","Stator resistance":"5.3 Ohm","Maximum current Irms":"10.8 A","Nominal output power":"430 W 115 V single phase 860 W 230 V single phase 1670 W 400 V three phase 1960 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Rotatable right angled connector","Electrical connection":"straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"5","Maximum axial force Fa":"300 N","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"98.2 lbf.in (11.1 N.m) 115...480 V three phase","IP degree of protection":"IP54 shaft bushing without shaft seal ring: conforming to IEC 60034-5 IP65 motor: conforming to IEC 60034-5 IP65 shaft bushing: conforming to IEC 60034-5","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":"4 A","Maximum mechanical speed":"4000 rpm","Network number of phases":"3","Number of mounting holes":"4","Product or Component Type":"Servo motor","Speed feedback resolution":"128 periods","[Us] rated supply voltage":"115...480 V","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/ef9b3bc9a6647aa18572bb7c1a22e9f5.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401M12A1000/sh3-servomotor-140mm-1-stack-high-torque-keyed-shaft-sincos-multiturn-128-no-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M12A1000/alternatives.json"},"ai":{"faq":[{"question":"How can I order SH31401M12A1000 or check availability?","answer":"Submit an RFQ for current pricing and lead time."},{"question":"What compliance documentation does Schneider Electric provide for this motor?","answer":"The motor conforms to IEC 60034-5 for IP protection.
