At 115 V single-phase it drops to 750 rpm, and at 230 V single-phase it runs 1500 rpm. Torque follows a similar pattern: nominal torque at 400 V three-phase is 9.2 N·m, and at 480 V three-phase it's 8.4 N·m. If you're wiring this into a 480 V line, you get the highest top speed but slightly less continuous torque; the 400 V three-phase supply gives the best torque-per-amp trade-off. Continuous stall torque is 11.1 N·m across the 115...480 V three-phase range, and peak stall torque hits 27 N·m — that's the transient overload ceiling for acceleration or deceleration. The continuous stall current is 7.8 A, and the maximum RMS current is 20.8 A, so the drive must be sized to supply that peak without tripping. ## Encoder feedback and IP sealing for washdown cells The encoder is an absolute multiturn SinCos Hiperface — this gives position feedback on power-up without a homing move, and the SinCos analog track provides fine interpolation for the drive's current loop. The motor carries IP65 on both the housing and the shaft bushing, so it handles washdown in food or beverage lines as long as the mating connector is also IP-rated. Cooling is natural convection — no fan, so the thermal budget depends on the mounting flange's ability to sink heat into the machine frame. The stator resistance is 1.41 Ω and inductance 23.72 mH, which sets the electrical time constant at about 17 ms — the drive's current regulator must be tuned for this L/R ratio to avoid overshoot.","metaTitle":"Schneider Electric SH31401P12A1100 Servo Motor, 2.9 kW","metaDescription":"Schneider Electric SH31401P12A1100 servo motor, 2.9 kW continuous, 3000 rpm at 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","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":"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/324511c117973c98a13876fee84b9eb2.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31401P12A1100/sh3-servomotor-140mm-1-stack-keyed-shaft-sincos-multiturn-128-no-brake-straight-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401P12A1100/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation is available for SH31401P12A1100?","answer":"The evidence does not list specific compliance certifications (RoHS, REACH, UL, IEC) for this order code.
