This is a time-saver on multi-axis machines where homing would otherwise eat into the cycle budget. The motor mounts on an international standard flange with a 140 mm flange size, a 130 mm centring collar diameter, and 11 mm mounting holes. The shaft is 24 mm diameter with a 50 mm smooth end — no keyway, so the coupling or pulley must be clamped. IP65 protection on both the motor body and the shaft bushing means it handles washdown environments without a secondary cover. Cooling is by natural convection — no external fan or forced air required. The thermal limit is set by the copper winding temperature at 130 °C, with a torque constant of 1.43 N·m/A at that hot condition. The stator resistance is 1.41 Ω and inductance is 23.72 mH, which the drive's current loop must be tuned to match. ## Electrical connection and load ratings The electrical connection is a straight connector — no right-angle adapter needed for tight cable egress. The motor is three-phase, with a continuous stall current of 7.8 A and a maximum RMS current of 20.8 A. The back EMF constant is 100 V/krpm at 20 °C, so at 3000 rpm the generated voltage is 300 V line-to-line — the drive's DC bus must be high enough to overcome this during regeneration. Maximum radial force at the shaft is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm. Maximum axial force is 300 N. These limit the overhung load from a belt drive or direct coupling — exceeding them shortens bearing life.","metaTitle":"Schneider Electric SH31401P02A1100 Servo Motor, 2.9 kW","metaDescription":"Schneider Electric SH31401P02A1100 servo motor, 2.9 kW continuous power, 400 V three phase, IP65, absolute multiturn SinCos Hiperface 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","Shaft end":"Smooth shaft","Encoder type":"Absolute multiturn 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","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/14ee865c555ff86fe1d46afcda3bb323.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31401P02A1100/servo-motor-sh3-140-111nmnokeymultinobrakestr-connip65-ip654k-rpm/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401P02A1100/alternatives.json"},"ai":{"faq":[{"question":"What is the nominal torque of SH31401P02A1100 at 400 V three-phase?","answer":"At 400 V three-phase and 3000 rpm nominal speed, the torque is 9.2 N·m.
