Nominal speed shifts with voltage: 1500 rpm at 400 V three-phase, 1800 rpm at 480 V three-phase. Nominal torque holds around 10.6 Nm at 400 V three-phase and 10.4 Nm at 480 V three-phase — the motor delivers consistent torque across the common industrial voltage range. Peak stall torque reaches 27 Nm for short-duration moves. ## Encoder and feedback — what mates with the drive Absolute single-turn SinCos Hiperface encoder — this is a position feedback standard used across Schneider and third-party drives. The SinCos analog tracks provide fine position interpolation; the Hiperface protocol handles the absolute position over a serial link. Confirm the drive's encoder interface supports Hiperface before wiring. Back EMF constant is 193 V/krpm at 20 °C — this sets the voltage the motor generates back into the drive at speed. The torque constant is 2.78 Nm/A at 120 °C copper temperature, useful for sizing the drive's current loop. ## Mounting and mechanical interface 140 mm (5.5 in) international standard flange with a 130 mm centring collar — this is the IEC metric flange pattern common on European-spec machines. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and 8 mm key width. Overall length is 217.5 mm (8.6 in) from the mounting face. The electrical connection uses a rotatable right-angled connector or a straight connector — the rotatable option helps in tight cable-routing spaces. No holding brake on this variant — for vertical-axis or Z-axis applications where the load must hold position with power off, a brake-equipped version is needed. The IP rating depends on the shaft seal: IP54 without the shaft seal ring, IP65 with it fitted. ## Sourcing and lifecycle — active production Natural convection cooling — no external fan or forced air required. The motor relies on its own surface area and mounting flange to dissipate heat, so the surrounding enclosure must allow free airflow around the frame.","metaTitle":"Schneider Electric SH31401M11A1000 Servo Motor, 1700 W","metaDescription":"Schneider Electric SH31401M11A1000 SH3 servo motor, 1700 W continuous power, 11 Nm nominal torque, 4000 rpm max speed, absolute Hiperface encoder, IP54/IP65","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 single turn 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/aec9af8bc3af176835d9d741bac4ea95.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401M11A1000/sh3-servomotor-140mm-1-stack-high-torque-keyed-shaft-sincos-singleturn-128-no-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M11A1000/alternatives.json"},"ai":{"faq":[{"question":"What is the SH31401M11A1000 used for?","answer":"This is a three-phase servo motor from the Schneider SH3 series, rated 1700 W continuous power with 11 Nm nominal torque.
