That peak figure — over 4× the continuous rating — is the number that governs acceleration and emergency stop profiles on a pick-and-place or rotary indexing station. Speed follows the supply: 3000 rpm at 400 V three-phase, 3600 rpm at 480 V three-phase, and 750/1500 rpm on single-phase 115/230 V respectively. The motor is wound for the higher voltage range; single-phase operation derates both torque and speed. ## Absolute single-turn SinCos Hiperface encoder — position at power-on, no homing cycle The encoder is an absolute single-turn SinCos Hiperface type. Single-turn means it tracks position within one revolution (typically 4096 or 65536 counts per turn depending on the resolution variant) and retains that value when power is removed. No homing sequence on restart — the axis knows where it is the instant the drive powers up, which saves a few seconds per cycle on multi-axis machines. SinCos analog tracks (1 Vpp sine/cosine) give the drive fine interpolation beyond the digital resolution, while the Hiperface protocol carries the absolute position data. The drive must support Hiperface interface — check compatibility with the intended servo drive model before wiring. ## IP65 motor body, IP67 housing — washdown-ready without a cover The motor body and shaft bushing meet IP65 per IEC 60034-5, and the housing meets IP67. That means the winding and bearings are protected against dust ingress and low-pressure water jets (IP65), and the housing can survive brief immersion (IP67). Suitable for food-and-bev washdown zones or outdoor conveyor sections where hose-down cleaning is routine. Natural convection cooling (no external fan) means no moving parts to ingest debris, but the thermal budget is set by the motor surface area and the ambient. In a confined cabinet or high-ambient environment, derate the continuous torque or add forced air across the housing. ## Electrical parameters for the drive tuning engineer Stator resistance is 0.28 Ohm, stator inductance 2.035 mH — these set the electrical time constant (L/R ≈ 7.3 ms) that the current loop must handle. The torque constant is 1.57 Nm/A at 120 °C copper temperature; the back EMF constant is 104 V/krpm at 20 °C. Both are temperature-sensitive: expect the torque constant to drop and the back EMF to rise as the motor warms to its 130 °C rated hot-spot temperature. Maximum RMS current is 95.6 A, with a 3-second peak of the same value — the peak current limit is set by the drive's output capability, not the motor's thermal limit. Use the drive's current-loop bandwidth to stay within the motor's demagnetisation curve; the datasheet's peak stall torque figure assumes the drive can deliver that current at the correct phase angle. ## Mounting dimensions and mechanical interface Motor flange size is 140 mm (5.5 in) with a centring collar diameter of 130 mm (5.1 in) and a centring collar depth of 3.5 mm (0.1 in). Mounting holes are 11 mm diameter on the flange bolt circle — standard for this frame size. The shaft is 24 mm diameter with a parallel key, key width 8 mm, shaft length 50 mm.","metaTitle":"Schneider Electric SH31404P11A1200 Servo Motor, 4040 W","metaDescription":"Schneider Electric SH31404P11A1200 SH3 servo motor, 4040 W continuous power, 30.2 Nm nominal torque at 400 V three-phase, IP65/IP67, absolute single-turn","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"15.06 in (382.5 mm)","Inertia":"0.0 kg.cm² of brake 23.7 kg.cm² of motor","Category":"US1PC5218359","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","Nominal speed":"750 rpm 115 V single phase 1500 rpm 230 V single phase 3000 rpm 400 V three phase 3600 rpm 480 V three phase","Rotor inertia":"23.7 kg.cm²","Nominal torque":"267.3 lbf.in (30.2 N.m) 115 V single phase 232.8 lbf.in (26.3 N.m) 230 V single phase 114.2 lbf.in (12.9 N.m) 400 V three phase 98.2 lbf.in (11.1 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.57 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"4040 W","Mounting Support":"International standard flange","Sizing reference":"SH31404P","Back emf constant":"104 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"1167.4 lbf.in (131.9 N.m) 115...480 V three phase","Stator inductance":"2.035 mH","Stator resistance":"0.28 Ohm","Maximum current Irms":"95.6 A","Nominal output power":"2370 W 115 V single phase 4130 W 230 V single phase 4040 W 400 V three phase 4190 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Straight connector","Electrical connection":"straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"5","Maximum axial force Fa":"300 N","Output current 3s peak":"95.6 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"295.6 lbf.in (33.4 N.m) 115...480 V three phase","IP degree of protection":"IP65 motor: conforming to IEC 60034-5 IP65 shaft bushing: conforming to IEC 60034-5 IP67 housing: conforming to IEC 60034-5","Maximum radial force Fr":"2660 N 1000 rpm 2110 N 2000 rpm 1840 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"21.3 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/59a962f140fbb64b90d8d0878862317c.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31404P11A1200/sh3-servomotor-140mm-4-stacks-keyed-shaft-sincos-singleturn-128-no-brake-straight-ip65-67/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31404P11A1200/alternatives.json"},"ai":{"faq":[{"question":"What is the nominal torque of SH31404P11A1200 at 400 V three-phase?","answer":"At 400 V three-phase, the nominal torque is 30.2 Nm (267.3 lbf.in).
