At 115 V single-phase, nominal torque is 24.7 Nm but nominal output power drops to 1940 W; at 400 V three-phase the same motor outputs 4050 W continuous. This means the same frame covers a wide application range, but the drive's DC bus voltage and the supply configuration determine the usable torque-speed envelope. The motor is rated for three-phase supply only — the single-phase figures reflect operation on a single-phase input drive that rectifies to a DC bus, not direct single-phase line connection. The peak stall torque of 90.2 Nm across the 115-480 V three-phase range gives headroom for acceleration transients without oversizing the frame. ## Encoder and feedback for position loop closure The absolute single-turn SinCos Hiperface encoder provides position feedback without a homing sequence on power-up — the drive reads the absolute position within one revolution from the encoder's memory. This eliminates the need for a reference run after each power cycle, saving cycle time in applications where the motor must resume position immediately. The torque constant of 1.58 Nm/A at 120 °C copper temperature and the back EMF constant of 105 V/krpm at 20 °C are the key parameters for drive commissioning: the drive's current loop gains and velocity feed-forward are tuned around these values. Stator resistance is 0.4 Ohm and inductance is 2.66 mH — these set the electrical time constant and the current regulator bandwidth. ## Mechanical integration and environmental sealing The motor mounts on an international standard flange with a 140 mm flange size and a 130 mm centring collar — this matches the IEC 72-1 frame size for direct coupling to standard gearboxes and linear actuators. The centring collar depth is 3.5 mm; the mounting holes are 11 mm diameter on the flange bolt circle. The smooth shaft is 24 mm diameter with a 50 mm shaft length — no keyway, so the coupling must transmit torque through a clamping or friction fit. The overall length is 327.5 mm from the mounting flange face to the rear of the encoder housing. Cooling is by natural convection only; no forced air or liquid cooling circuit is needed, but the motor must be mounted with adequate clearance for free air flow around the finned housing. ## Sourcing and lifecycle — active production The electrical connection uses a rotatable right-angled connector — this allows the cable exit orientation to be adjusted in 90° increments after mounting, simplifying cable routing in tight cabinets or on moving axes. The connector is part of the motor assembly and is not field-replaceable without disassembly.","metaTitle":"Schneider Electric SH31403P01A2100 Servo Motor, 4.1 kW","metaDescription":"Schneider Electric SH31403P01A2100 SH3 servo motor, 4.1 kW continuous, 24.7 Nm nominal torque at 400 V three-phase, IP65, absolute single-turn SinCos Hiperface","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31403P01A2100","Length":"12.9 in (327.5 mm)","Inertia":"0.0 kg.cm² of brake 17.94 kg.cm² of motor","Category":"US1PC5218359","Shaft end":"Smooth shaft","description":"SH3 servomotor, 140mm, 3 stacks, smooth Shaft, SinCos Singleturn 128, no Brake, angular, 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":"17.94 kg.cm²","Nominal torque":"218.6 lbf.in (24.7 N.m) 115 V single phase 187.6 lbf.in (21.2 N.m) 230 V single phase 114.2 lbf.in (12.9 N.m) 400 V three phase 80.5 lbf.in (9.1 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.58 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"4100 W","Mounting Support":"International standard flange","Sizing reference":"SH31403P","Back emf constant":"105 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"798.3 lbf.in (90.2 N.m) 115...480 V three phase","Stator inductance":"2.66 mH","Stator resistance":"0.4 Ohm","Maximum current Irms":"61.0 A","Nominal output power":"1940 W 115 V single phase 3330 W 230 V single phase 4050 W 400 V three phase 3430 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Rotatable right angled connector","Electrical connection":"rotatable right angled connector","Nbr. of units in pkg.":"1","Number of motor poles":"5.0","Maximum axial force Fa":"300 N","Output current 3s peak":"61.0 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"246.05 lbf.in (27.8 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":"2420 N 1000 rpm 1920 N 2000 rpm 1670 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"17.6 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/361be3cdbee8752b6840cb7d08b55fb7.pdf","sourceUrl":"https://www.se.com/be/en/product/SH31403P01A2100/sh3-servomotor-140mm-3-stacks-smooth-shaft-sincos-singleturn-128-no-brake-angular-ip65-65/"},"ai":{"faq":[{"question":"What is the continuous stall torque of the SH31403P01A2100?","answer":"The continuous stall torque is 27.8 Nm across the 115-480 V three-phase range.
