Nominal torque shifts slightly across these conditions, from 11 N·m down to 10.4 N·m at the highest voltage. Peak stall torque is 27 N·m across the full 115–480 V range, giving a 2.4:1 peak-to-continuous ratio for acceleration bursts. Continuous stall torque sits at 11.1 N·m, held indefinitely at zero speed under natural convection cooling. ## Encoder and feedback — no homing needed The absolute single-turn SinCos Hiperface encoder reports position at power-up without a reference move. On a machine that cycles power between shifts, this saves the homing sequence time and eliminates the risk of a crash if the home sensor fails. Back EMF constant is 193 V/krpm at 20 °C. At the 4000 rpm maximum mechanical speed, the back EMF reaches about 772 V line-to-line — the drive's DC bus must be rated above this to maintain current control. ## Mounting and mechanical interface The 140 mm IEC flange (centring collar 130 mm diameter, 3.5 mm deep) mates with standard gearbox input flanges. Four 11 mm mounting holes on the flange face secure the motor. Overall body length is 217.5 mm including the encoder and connector housing. Shaft is 24 mm diameter, 50 mm long, with an 8 mm parallel key. Maximum radial force at the shaft nose is 1930 N at 1000 rpm, dropping to 1340 N at 3000 rpm — bearing life follows the load at operating speed, not the static rating. Maximum axial force is 300 N. ## Thermal limits and cooling IP rating depends on the shaft seal: IP54 at the shaft bushing without the seal ring, IP65 on the motor body and shaft bushing with the seal fitted. For washdown environments, specify the sealed variant. ## Electrical connection and drive pairing The motor is a three-phase synchronous machine with 5 poles — an unusual pole count that the drive's commutation algorithm must support. Maximum RMS current is 10.8 A; the drive should be sized to supply this during acceleration. Stator inductance is 88.55 mH, which keeps current ripple low but may limit high-speed torque if the drive's voltage is marginal. Electrical connection options are a straight connector or a rotatable right-angled connector — the right-angle version helps when the cable must route close to a panel wall. The torque constant is 2.78 N·m/A at 120 °C winding temperature. Sourced through independent distribution channels.","metaTitle":"Schneider Electric SH31401M11A2000 Servo Motor, 1700 W","metaDescription":"Schneider Electric SH31401M11A2000 SH3 servo motor, 1700 W continuous, 11.1 N·m continuous stall torque, 140 mm flange, 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":"Straight connector","Electrical connection":"rotatable right angled 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/ceaf94dd6021bad9dbdcecafe356ca06.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401M11A2000/servo-motor-sh3-140-111nmkeysinglenobrake90conn-ip54-ip654k-rpm/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M11A2000/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of SH31401M11A2000?","answer":"Continuous stall torque is 11.1 N·m (98.2 lbf·in) across the 115–480 V range.
