The nominal torque sits at 18.6 Nm, and the continuous stall torque is 19.5 Nm across the 115-480 V three-phase range. That flat torque curve from stall to rated speed means it handles constant-torque loads like conveyors or feed axes without derating through the mid-range. Peak stall torque reaches 60.1 Nm — roughly 3x the continuous rating — giving headroom for acceleration transients on a pick-and-place gantry or a press axis. The maximum mechanical speed of 4000 rpm leaves a 25% overspeed margin above nominal, useful for rapid traverses or light-load positioning moves. ## Feedback and environmental sealing The absolute multiturn SinCos Hiperface encoder provides position feedback without a home cycle on power-up — the multiturn count tracks absolute position over multiple shaft revolutions. This matters for applications where the machine must resume from the last known position after a power loss, such as a rotary index table or a vertical axis that needs to avoid a crash on restart. IP65 rating on both the motor body and the shaft bushing means it withstands washdown and dust ingress per IEC 60034-5. The straight connector and smooth shaft simplify cable routing and coupling installation in tight cabinet-to-machine transitions. Natural convection cooling eliminates the fan — no moving parts to fail, but the thermal budget relies on the motor flange conducting heat into the machine frame, so mounting on a thermally conductive surface is the baseline assumption. ## Electrical parameters and drive matching Stator resistance is 0.6 Ohm and inductance is 11.225 mH — these set the electrical time constant and influence the current-loop tuning on the drive. The torque constant of 1.47 Nm/A at 120 °C and back-EMF constant of 101 V/krpm at 20 °C let you calculate the required drive current and bus voltage for a given speed-torque operating point. Continuous stall current is 13.2 A, with a maximum RMS current of 44.1 A — the drive must supply at least that peak for acceleration transients. ## Mechanical interface and bearing loads The 140 mm flange with a 130 mm centring collar and 3.5 mm collar depth mounts to standard international flange patterns. Four M11 mounting holes on the flange — the bolt circle diameter is not listed, but the flange size and centring collar match the SH3 frame standard. The 24 mm smooth shaft with a 50 mm shaft length couples to the load via a flexible jaw or bellows coupling; the smooth shaft means no keyway stress risers, but the coupling must transmit torque purely through friction or a clamping element. Maximum radial force is 2240 N at 1000 rpm, derating to 1550 N at 3000 rpm — this sets the allowable belt tension or overhung load from a pulley. Maximum axial force is 300 N, typical for a servo motor with sealed bearings; any external thrust load from a helical gear or a leadscrew must stay under that limit or the motor bearings will wear prematurely.","metaTitle":"Schneider Electric SH31402P02A1100 Servo Motor, 3.9 kW","metaDescription":"Schneider Electric SH31402P02A1100 SH3 servo motor, 3.9 kW continuous power, 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":"10.7 in (272.5 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":"12.68 kg.cm²","Nominal torque":"164.6 lbf.in (18.6 N.m) 115 V single phase 151.3 lbf.in (17.1 N.m) 230 V single phase 108.9 lbf.in (12.3 N.m) 400 V three phase 85.9 lbf.in (9.7 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.47 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"3900 W","Mounting Support":"International standard flange","Sizing reference":"SH31402P","Back emf constant":"101 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"531.9 lbf.in (60.1 N.m) 115...480 V three phase","Stator inductance":"11.225 mH","Stator resistance":"0.6 Ohm","Maximum current Irms":"44.1 A","Nominal output power":"1460 W 115 V single phase 2690 W 230 V single phase 3860 W 400 V three phase 3660 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":"172.6 lbf.in (19.5 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":"2240 N 1000 rpm 1780 N 2000 rpm 1550 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"13.2 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/efe046d6e7a1ee93f60292109fa583f5.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31402P02A1100/sh3-servomotor-140mm-2-stacks-smooth-shaft-sincos-multiturn-128-no-brake-straight-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31402P02A1100/alternatives.json"},"ai":{"faq":[{"question":"What is SH31402P02A1100's listed phase and length?","answer":"The motor is a three-phase design with an overall length of 10.7 inches (272.5 mm)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH31402P02A1100","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/SH31402P02A1100 when reusing this data.
