Peak stall torque reaches 27 N.m across the full three-phase voltage band, giving a 2.4× overload margin over the continuous stall torque of 11.1 N.m — enough for aggressive acceleration profiles without oversizing the frame. The 1700 W continuous power rating assumes natural convection cooling, so no external blower or forced air is needed — mount it with the standard 140 mm flange and let the frame dissipate the heat. ## Encoder feedback and drive tuning parameters The absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — critical for applications where the axis must resume from the last known position after a power loss. Stator inductance of 88.55 mH and stator resistance of 5.3 Ohm set the electrical time constant at roughly 16.7 ms — the drive's current loop gains need tuning to this L/R ratio for stable torque control at the 10.8 A maximum RMS current. The torque constant is 2.78 N.m/A at 120 °C copper temperature, and the back EMF constant is 193 V/krpm at 20 °C — use these to calculate the voltage margin at 4000 rpm max mechanical speed so the drive bus voltage doesn't saturate. Five motor poles means the drive must be configured for a 5-pole motor — not the common 4- or 6-pole defaults — or the speed feedback loop will oscillate. ## Mechanical integration and load limits The 140 mm flange with 130 mm centring collar and 11 mm mounting holes bolts onto standard IEC metric patterns — the 3.5 mm centring collar depth registers the pilot bore before the bolts take the shear load. Shaft is 24 mm diameter with a parallel key, 50 mm shaft length — the 8 mm key width matches standard metric key stock for pulley or coupling fitment. Maximum radial force is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm — bearing life calculations must use the actual speed-dependent Fr limit, not the static rating. Maximum axial force is 300 N — thrust loads from helical gears or lead screws must stay under this or an external thrust bearing is needed. ## Environmental sealing and cable routing IP65 rating applies to both the motor body and the shaft bushing per IEC 60034-5 — the seal at the shaft exit is the wet-end barrier, so washdown spray hitting the front face won't ingress past the bushing. Electrical connection options include a rotatable right-angled connector and a straight connector — the rotatable version lets the cable exit in any quadrant without adding a junction box, useful in tight machine envelopes. No holding brake is fitted on this variant — for vertical axes or safety-hold applications, an external brake or a motor with the brake option must be specified. Packaged as a single unit — order the exact quantity needed; no MOQ surprises for prototype or MRO quantities.","metaTitle":"Schneider Electric SH31401M12A1100 Servo Motor, 1700 W","metaDescription":"Schneider Electric SH31401M12A1100 SH3 servo motor, 1700 W continuous, 11 Nm nominal torque, IP65, absolute multiturn 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":"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/4c89d77efaa7e0d3c2581932a019450d.pdf","sourceUrl":"https://www.se.com/nl/en/product/SH31401M12A1100/sh3-servomotor-140mm-1-stack-high-torque-keyed-shaft-sincos-multiturn-128-no-brake-straight-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M12A1100/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for SH31401M12A1100?","answer":"No stock-holding claim is made here; the quote reflects real-time supply."},{"question":"What is SH31401M12A1100's listed phase on this Servo Motors with Brake line?","answer":"The motor is designed for three-phase network connection — it operates on three-phase supplies from 115 V to 480 V, with speed and torque varying by voltage as listed in the spec table."},{"question":"What is SH31401M12A1100's listed length on this Servo Motors with Brake line?","answer":"The overall body length is 8.6 inches (217.5 mm) — this excludes the shaft extension and connector protrusion, so measure the full envelope including the rotatable connector before panel layout."},{"question":"What compliance documentation does Schneider Electric provide for SH31401M12A1100?","answer":"The motor carries IP65 rating per IEC 60034-5.
