On three-phase 400 V it delivers 1500 rpm nominal speed, 10.6 Nm nominal torque, and 1670 W nominal output power. On three-phase 480 V the speed rises to 1800 rpm with 10.4 Nm torque and 1960 W output. Single-phase operation is possible but derated: 115 V single-phase yields 375 rpm, 11 Nm torque, 430 W; 230 V single-phase gives 750 rpm, 10.95 Nm, 860 W. The continuous stall torque is 11.1 Nm across the 115–480 V three-phase range, and peak stall torque reaches 27 Nm. Continuous power rating is 1700 W — this is the thermal limit under natural convection cooling (no forced ventilation). The maximum mechanical speed is 4000 rpm, above the nominal speeds, so the motor can be over-sped if the drive and load allow. ## Encoder and feedback — absolute multiturn SinCos Hiperface The encoder is an absolute multiturn SinCos Hiperface type. This protocol provides position and speed feedback over a single cable pair, with multiturn count retained through power cycles — no homing routine needed on restart. Drive compatibility is limited to drives that support Hiperface; confirm your drive's feedback interface before specifying. The torque constant is 2.78 Nm/A at 120 °C copper temperature, and the back-EMF constant is 193 V/krpm at 20 °C. These values are needed for drive tuning and for calculating the DC-bus voltage headroom at high speed. ## Mechanical interface — flange, shaft, and mounting dimensions The 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. This is an international standard flange — compatible with common gearbox and machine interfaces. The shaft is 24 mm diameter, 50 mm length, with an 8 mm keyway and parallel key. Maximum radial force is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm. Maximum axial force is 300 N. These limits govern bearing life and mounting stiffness — overshoot them and the bearing race spalls. ## Environmental protection and cooling The IP rating depends on the shaft seal configuration. Without the shaft seal ring, the shaft bushing is IP54 — suitable for dry indoor environments with some dust ingress protection. With the shaft seal ring fitted, the motor achieves IP65 — washdown-rated, suitable for food-and-bev lines or wet machining areas. The motor body itself is IP65-rated. Cooling is by natural convection — no fan, no forced air. The continuous power and torque ratings assume free airflow around the motor body; mounting in a confined space or against a heat source will require derating. ## Electrical parameters for drive tuning Stator resistance is 5.3 Ω, stator inductance is 88.55 mH. These values set the electrical time constant and influence the drive's current-loop tuning. The continuous stall current is 4 A; the maximum RMS current is 10.8 A — the drive must be sized to supply at least this peak current for acceleration and peak torque events. The motor has 5 poles (10-pole equivalent on the rotor). The copper hot-spot temperature limit is 130 °C — the drive's thermal model should be configured to protect the winding at this threshold. ## Connection and cabling The electrical connection is available as either a straight connector or a rotatable right-angled connector. The rotatable option helps route the cable in tight cabinets where a straight connector would interfere with the enclosure wall or adjacent components.","metaTitle":"Schneider Electric SH31401M12A2000 Servo Motor, 1700 W","metaDescription":"Schneider Electric SH31401M12A2000 SH3 servo motor, 1700 W continuous, 11 Nm stall torque, absolute multiturn SinCos 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 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":"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/a789ea6e0ec6cf6afdd0ae6fec8986a4.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401M12A2000/sh3-servomotor-140mm-1-stack-high-torque-keyed-shaft-sincos-multiturn-128-no-brake-angular-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M12A2000/alternatives.json"},"ai":{"faq":[{"question":"What is the closest alternative to SH31401M12A2000 in the SH3 family?","answer":"The SH31401M12A2000 is the specific variant with a 140 mm flange, 24 mm shaft, absolute Hiperface encoder, and no holding brake.
