Nominal speed shifts with supply: 500 rpm at 115 V single-phase, 1000 rpm at 230 V single-phase, 2000 rpm at 400 V three-phase, and 2400 rpm at 480 V three-phase. The 4-pole motor and back EMF constant of 148 V/krpm at 20 °C set the speed-voltage relationship. Continuous stall torque is 8 Nm across the 115–480 V three-phase range, with a continuous stall current of 3.4 A. Peak stall torque reaches 28.3 Nm at 14.7 A peak current — useful for acceleration transients but limited by the 3-second peak output rating. ## Encoder feedback and environmental sealing The absolute single-turn SinCos Hiperface encoder provides position feedback without a homing cycle on power-up — the single-turn resolution is sufficient for applications that don't need multi-turn tracking. The straight connector mates with standard Hiperface cables; verify the cable pinout matches the drive's encoder input. IP65 on the motor body and shaft bushing, IP67 on the housing — the motor withstands washdown and dust ingress per IEC 60034-5. The shaft seal and housing gasket are the wet-end barriers; the connector O-ring must be seated for the IP67 rating to hold.","metaTitle":"Schneider Electric SH31003M11A1200 Servo Motor, 1500 W, 8 Nm","metaDescription":"Schneider Electric SH31003M11A1200 servo motor, 1500 W continuous power, 8 Nm continuous stall torque, absolute single-turn SinCos Hiperface encoder, IP65/IP67.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"9.5 in (240.5 mm)","Inertia":"0.0 kg.cm² of brake 3.22 kg.cm² of motor","Key width":"0.2 in (6 mm)","Shaft end":"Parallel key","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"1.6 in (40 mm)","Holding brake":"Without","Nominal speed":"500 rpm 115 V single phase 1000 rpm 230 V single phase 2000 rpm 400 V three phase 2400 rpm 480 V three phase","Rotor inertia":"3.22 kg.cm²","Nominal torque":"69.04 lbf.in (7.8 N.m) 115 V single phase 66.4 lbf.in (7.5 N.m) 230 V single phase 62.0 lbf.in (7 N.m) 400 V three phase 59.83 lbf.in (6.76 N.m) 480 V three phase","Shaft diameter":"0.7 in (19 mm)","Torque constant":"2.35 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"1500 W","Mounting Support":"International standard flange","Sizing reference":"SH31003M","Back emf constant":"148 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"3.9 in (100 mm)","Peak stall torque":"250.5 lbf.in (28.3 N.m) 115...480 V three phase","Stator inductance":"17.4 mH","Stator resistance":"5.3 Ohm","Maximum current Irms":"14.7 A","Nominal output power":"410 W 115 V single phase 790 W 230 V single phase 1470 W 400 V three phase 1700 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":"4","Maximum axial force Fa":"160 N","Output current 3s peak":"14.7 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"70.8 lbf.in (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 IP67 housing: conforming to IEC 60034-5","Maximum radial force Fr":"1050 N 1000 rpm 830 N 2000 rpm 730 N 3000 rpm 660 N 4000 rpm","Mounting holes diameter":"0.4 in (9.0 mm)","Centring collar diameter":"3.7 in (95 mm)","Continuous stall current":"3.4 A","Maximum mechanical speed":"6000 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":"4.5 in (115 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5a5ddcf96c4c19695a6da8d7a7724e7a.pdf","sourceUrl":"https://www.se.com/nl/en/product/SH31003M11A1200/sh3-servomotor-100mm-3-stacks-high-torque-keyed-shaft-sincos-singleturn-128-no-brake-straight-ip65-67/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31003M11A1200/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous power rating of SH31003M11A1200?","answer":"The continuous power rating is 1500 W.
