Nominal speed reaches 3000 rpm on that supply, with a maximum mechanical speed of 4000 rpm — the safe overspeed ceiling for the rotor assembly. Torque output is supply-dependent: at 400 V three-phase, nominal torque is 9.2 Nm, while peak stall torque hits 27 Nm across the 115–480 V three-phase range. The continuous stall torque sits at 11.1 Nm, drawn at 7.8 A continuous stall current. Feedback comes from an absolute single-turn SinCos Hiperface encoder — no need for a homing sequence on power-up, which simplifies commissioning on multi-axis lines where absolute position must be retained through a power cycle. ## IP65/IP67 sealed housing, natural convection cooling The motor carries IP65 on the body and shaft bushing, with IP67 on the housing per IEC 60034-5 — meaning it withstands hose-directed water and dust ingress. This suits washdown zones in food processing or outdoor conveyor sections where moisture is constant. Cooling is natural convection — no external fan or forced air required. In a confined cabinet or high-ambient installation, the thermal limit (130 °C copper hot-spot) will be reached sooner than with a fan-cooled equivalent; account for derating if the motor is enclosed. Electrical connection is via a straight connector, which simplifies cable routing in tight panels compared to a right-angle version. The flange is an international standard 140 mm size (5.5 in) with a 130 mm centring collar and 3.5 mm collar depth — a common interface for gearboxes and mounting brackets. ## Shaft and mechanical interface for direct coupling The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and an 8 mm key width — a standard metric keyway that mates with common couplings and pulleys. Maximum radial force at 1000 rpm is 1930 N, dropping to 1340 N at 3000 rpm; axial force limit is 300 N. These set the bearing life envelope for belt-driven or overhung loads. Stator resistance is 1.41 Ω and inductance 23.72 mH — these electrical parameters are needed for the drive's autotune routine and for thermal modeling of the winding at sustained overload. No official successor or cross-reference exists for this order code — it is the current build. The sizing reference SH31401P identifies the frame; the suffix 11A1200 encodes the winding, encoder, and connector variant. For volume or project pricing, a quote request with the target quantity and delivery schedule is the standard path.","metaTitle":"Schneider Electric SH31401P11A1200 Servo Motor, 2.9 kW","metaDescription":"Schneider Electric SH31401P11A1200 SH3 servo motor, 2.9 kW continuous, 3000 rpm at 400 V three-phase, IP65, absolute SinCos 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)","Category":"18359-PACDRIVE3 SERVO MOTORS","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":"7.41 kg.cm²","Nominal torque":"96.92 lbf.in (10.95 N.m) 115 V single phase 93.8 lbf.in (10.6 N.m) 230 V single phase 81.4 lbf.in (9.2 N.m) 400 V three phase 74.3 lbf.in (8.4 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.43 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"2900 W","Mounting Support":"International standard flange","Sizing reference":"SH31401P","Back emf constant":"100 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":"23.72 mH","Stator resistance":"1.41 Ohm","Maximum current Irms":"20.8 A","Nominal output power":"860 W 115 V single phase 1670 W 230 V single phase 2890 W 400 V three phase 3170 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","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 IP67 housing: 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":"7.8 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/36d16536125619987e6f6b626c975e54.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31401P11A1200/servo-motor-sh3-140-111nmkeysinglenobrakestr-connip65-ip674k-rpm/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401P11A1200/alternatives.json"},"ai":{"faq":[{"question":"What is the nominal speed and torque of SH31401P11A1200 at 400 V three-phase?","answer":"At 400 V three-phase, nominal speed is 3000 rpm and nominal torque is 9.2 Nm.
