The absolute single-turn SinCos Hiperface encoder reports position at power-up without a homing sequence, which saves cycle time on machines that power-cycle between production runs. IP65 protection on both the motor body and shaft bushing means this motor can be mounted directly on a machine frame in washdown or dusty environments without a separate enclosure — the seal is at the shaft exit, not just the housing. ## Speed-torque envelope depends on supply voltage At 400 V three-phase input, the motor delivers 3000 rpm nominal speed with 9.2 Nm nominal torque and 2890 W output power. On 480 V three-phase, speed reaches 3600 rpm with 8.4 Nm torque at 3170 W. On single-phase supplies, performance drops significantly: 115 V single-phase yields 750 rpm / 10.95 Nm / 860 W, while 230 V single-phase gives 1500 rpm / 10.6 Nm / 1670 W. The motor is usable on single-phase but the speed range is halved. Continuous stall torque is 11.1 Nm across the 115–480 V three-phase range, with a continuous stall current of 7.8 A. Peak stall torque reaches 27 Nm, limited by the 20.8 A maximum RMS current. ## Electrical parameters for drive tuning and sizing Stator resistance is 1.41 Ω and stator inductance is 23.72 mH — these values feed the auto-tuning routine in the servo drive for current-loop gains and field-weakening thresholds. The torque constant is 1.43 Nm/A at 120 °C copper temperature, and the back EMF constant is 100 V/krpm at 20 °C — both needed for the drive's velocity-loop feedforward calculations. ## Mechanical mounting and shaft details The motor uses an international standard flange with 140 mm flange size, 130 mm centring collar diameter, and 3.5 mm centring collar depth — matches standard IEC frame dimensions for direct bolt-up to gearboxes or machine frames. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and 8 mm key width. Maximum radial force is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm; maximum axial force is 300 N. Cooling is by natural convection — no external fan or forced air required, but the mounting surface must allow free airflow around the finned housing for rated continuous torque. The electrical connection uses a straight connector — confirm the mating connector type and pinout from the motor's installation manual before panel wiring.","metaTitle":"Schneider Electric SH31401P11F1100 Servo Motor with Brake","metaDescription":"Schneider Electric SH31401P11F1100 SH3 servo motor with holding brake, 2.9 kW continuous, 3000 rpm at 400 V three-phase, IP65, absolute encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"10.06 in (255.5 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":"With","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":"9.21 kg.cm²","Holding torque":"203.6 lbf.in (23 N.m)","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/2222668b290b0c0aeb43230ca0f77b77.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401P11F1100/sh3-servomotor-140mm-1-stack-keyed-shaft-sincos-singleturn-128-brake-straight-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401P11F1100/alternatives.json"},"ai":{"faq":[{"question":"What supply voltages does SH31401P11F1100 work with?","answer":"The motor is a three-phase design but operates on single-phase supplies as well.
