The torque constant is 1.43 N.m/A at 120 °C copper temperature, so the drive current loop must be tuned to this value for accurate torque control. Nominal speed varies by supply: 750 rpm at 115 V single-phase, 1500 rpm at 230 V single-phase, 3000 rpm at 400 V three-phase, and 3600 rpm at 480 V three-phase. The maximum mechanical speed is 4000 rpm — the drive's overspeed limit must be set below this. ## Encoder feedback and IP65 sealing The absolute single-turn SinCos Hiperface encoder provides position feedback on power-up without a homing sequence — critical for servo axes that must resume position after a power cycle. The straight electrical connector mates with standard Hiperface cabling. IP65 protection on both the motor body and shaft bushing (per IEC 60034-5) means this motor withstands washdown and dusty environments common in food processing, packaging, and material handling lines. Natural convection cooling keeps the design simple — no fan to clog or fail. ## Mounting and mechanical interface The motor mounts on an international standard flange with a 140 mm (5.5 in) flange size and 130 mm centring collar diameter. The shaft is 24 mm diameter with a parallel key, 50 mm shaft length, and 8 mm key width — a common interface for direct coupling to ball screws or timing belt pulleys. ## Electrical parameters for drive selection Stator resistance is 1.41 Ohm and stator inductance is 23.72 mH — these values set the electrical time constant and influence the drive's current regulator tuning. The back EMF constant is 100 V/krpm at 20 °C, which determines the bus voltage needed to reach rated speed. Continuous stall current is 7.8 A, with a maximum current Irms of 20.8 A. The drive must be sized to supply at least this peak current during acceleration or stall conditions. The peak stall torque is 27 N.m across the 115...480 V three-phase range.","metaTitle":"Schneider Electric SH31401P11A1100 Servo Motor, 2900 W","metaDescription":"Schneider Electric SH31401P11A1100 SH3 servo motor, 2900 W continuous power, three-phase, IP65, absolute SinCos Hiperface encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31401P11A1100","Length":"8.6 in (217.5 mm)","Category":"18359-PACDRIVE3 SERVO MOTORS","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","description":"SH3 servomotor, 140mm, 1 stack, keyed Shaft, SinCos Singleturn 128, no Brake, straight, IP65/65","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","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/7f08f9ca82145397a4aa20f2fd652967.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401P11A1100/sh3-servomotor-140mm-1-stack-keyed-shaft-sincos-singleturn-128-no-brake-straight-ip65-65/"},"ai":{"faq":[{"question":"What is the phase configuration of SH31401P11A1100?","answer":"It is a three-phase servo motor.
