Overall length is 10.7 in (272.5 mm) with a 0.9 in (24 mm) shaft diameter, 2.0 in (50 mm) shaft length, and a parallel key — the shaft end is keyed, so the coupling or pulley bore must match the 8 mm key width. The motor is naturally convection-cooled (no external fan), so the mounting surface acts as the primary heat sink — derate the continuous torque if bolted to a thermally insulating bracket. ## Torque and speed across supply voltages — the voltage dependency matters This SH3 motor delivers 164.6 lbf·in (18.6 N·m) nominal torque at 750 rpm on 115 V single-phase, 151.3 lbf·in (17.1 N·m) at 1500 rpm on 230 V single-phase, 108.9 lbf·in (12.3 N·m) at 3000 rpm on 400 V three-phase, and 85.9 lbf·in (9.7 N·m) at 3600 rpm on 480 V three-phase — the torque-speed envelope shifts with the input rail, so the drive's DC bus voltage sets the available shaft power. Continuous stall torque is 172.6 lbf·in (19.5 N·m) across the 115...480 V three-phase range — that's the holding torque at zero speed before thermal limits kick in. Peak stall torque hits 531.9 lbf·in (60.1 N·m) on three-phase supply — roughly 3× the continuous stall figure, available for acceleration transients within the 44.1 A peak current limit. ## Encoder feedback and electrical data — absolute single-turn Hiperface The motor ships with an absolute single-turn SinCos Hiperface encoder — this is a digital-plus-analog hybrid feedback protocol that carries position data over a serial link while the analog SinCos tracks fine interpolation; the drive must support Hiperface to read the absolute position on power-up. Stator resistance is 0.6 Ω and stator inductance is 3.855 mH — these values set the I²R heating floor and the current-loop bandwidth the drive needs to tune. Torque constant is 1.47 N·m/A at 248 °F (120 °C) hot copper — the motor produces 1.47 N·m per amp of RMS current once the windings reach thermal equilibrium. Back EMF constant is 101 V/krpm at 68 °F (20 °C) — at 3000 rpm the motor generates about 303 V line-to-line back EMF, which must stay below the drive's DC bus voltage to maintain current control. ## Environmental protection and mechanical limits — IP65, radial and axial loads IP65 on the motor body and shaft bushing per IEC 60034-5, with IP67 on the housing — the motor withstands washdown spray from any direction, but the straight connector (not angled) must be oriented to avoid pooling at the seal face. Maximum radial force Fr is 2240 N at 1000 rpm, dropping to 1550 N at 3000 rpm — the bearing life calculation uses this speed-dependent curve, not a single static figure. Maximum axial force Fa is 300 N — this is the thrust limit for direct-coupled loads; a belt drive that pulls axially will exceed it unless the pulley is located against a shoulder.","metaTitle":"Schneider Electric SH31402P11A1200 Servo Motor, 3900 W","metaDescription":"Schneider Electric SH31402P11A1200 SH3 servo motor, 3900 W continuous power, 140 mm flange, IP65, absolute single-turn 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":"SH31402P11A1200","Length":"10.7 in (272.5 mm)","Inertia":"0.0 kg.cm² of brake 12.68 kg.cm² of motor","Category":"US1PC5218359","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","description":"SH3 servomotor, 140mm, 2 stacks, keyed Shaft, SinCos Singleturn 128, no Brake, straight, IP65/67","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":"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":"3.855 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","Output current 3s peak":"44.1 A","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 IP67 housing: 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/2eb1efce713139e2ec87ca86af9b78de.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31402P11A1200/sh3-servomotor-140mm-2-stacks-keyed-shaft-sincos-singleturn-128-no-brake-straight-ip65-67/"},"ai":{"faq":[{"question":"What is SH31402P11A1200's listed phase and length?","answer":"The motor is a three-phase design with an overall length of 10.7 in (272.5 mm)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH31402P11A1200","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/SH31402P11A1200 when reusing this data.
