Nominal torque drops as voltage rises: 164.6 lbf.in at 115 V single-phase, 108.9 lbf.in at 400 V three-phase, and 85.9 lbf.in at 480 V three-phase. The drive must be sized for the full-load current at the target operating point. Continuous power is 3900 W, but nominal output power varies from 1460 W at 115 V single-phase to 3860 W at 400 V three-phase. The motor's thermal limit is 3900 W; the actual output depends on the drive supply and duty cycle. ## Brake torque and vertical-load safety The holding brake delivers 203.6 lbf.in (23 N.m) — this is the torque that holds the load at rest with the motor de-energized. For a vertical axis, the load torque at the motor shaft must stay below this value to prevent drift when power is removed. The brake is spring-applied, power-released; it engages on power loss or drive disable. Peak stall torque is 531.9 lbf.in (60.1 N.m) across the 115...480 V three-phase range — this is available for acceleration and deceleration only, not continuous duty. The continuous stall torque is 172.6 lbf.in (19.5 N.m) over the same voltage range. ## Encoder feedback and positioning The absolute single-turn SinCos Hiperface encoder reports position within one revolution at power-up — no homing sequence is needed for single-turn applications. For multi-turn position, an external battery-backed multi-turn encoder or a separate absolute multi-turn device is required. The SinCos analog tracks give fine interpolation for velocity and position loops. The torque constant is 1.47 N.m/A at 248 °F (120 °C) hot winding temperature — the drive current loop must be tuned for this value. The back EMF constant is 101 V/krpm at 68 °F (20 °C); at 3000 rpm the back EMF reaches ~303 V, so the drive DC bus must be at least 340 V to deliver current into the motor. ## Environmental sealing and mechanical limits IP65 on the motor body and shaft bushing, IP67 on the housing — the motor survives washdown and hose-directed water, but the shaft bushing seal is the weaker point. The shaft bushing is rated IP65, not IP67, so high-pressure washdown directed at the shaft seal may breach it. The housing is fully IP67. Maximum radial force at the shaft is 2240 N at 1000 rpm, derating to 1550 N at 3000 rpm. Maximum axial force is 300 N — this motor cannot support significant thrust loads. For belt-drive or leadscrew applications with axial loads above 300 N, an external thrust bearing is required. The motor uses a 140 mm international standard flange, 24 mm shaft diameter with parallel key, and a straight electrical connector. The mounting holes are 0.4 in (11 mm) diameter on the flange. The overall length is 12.2 in (310.5 mm).","metaTitle":"Schneider Electric SH31402P11F1200 Servo Motor with Brake","metaDescription":"Schneider Electric SH31402P11F1200 servo motor with brake, 3900 W continuous power, 44.1 A max current, IP65/IP67, absolute single-turn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31402P11F1200","Length":"12.2 in (310.5 mm)","Inertia":"1.8 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, Brake, straight, IP65/67","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"With","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":"14.48 kg.cm²","Holding torque":"203.6 lbf.in (23 N.m)","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/977e3b729b5d8d70c1f74b45df5c01eb.pdf","sourceUrl":"https://www.se.com/ie/en/product/SH31402P11F1200/sh3-servomotor-140mm-2-stacks-keyed-shaft-sincos-singleturn-128-brake-straight-ip65-67/"},"ai":{"faq":[{"question":"What supply voltage and speed does SH31402P11F1200 support?","answer":"The motor delivers 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.
