At 480 V three-phase the nominal output power rises to 1960 W and the speed to 1800 rpm. Single-phase supply options produce lower ratings: 430 W at 115 V / 375 rpm, and 860 W at 230 V / 750 rpm. Nominal torque varies with supply as well — 11 N.m at 115 V single-phase, 10.95 N.m at 230 V single-phase, 10.6 N.m at 400 V three-phase, and 10.4 N.m at 480 V three-phase. The continuous stall torque is 11.1 N.m across the 115–480 V three-phase range, with a continuous stall current of 4 A. ## Feedback and electrical parameters Encoder is an absolute multiturn SinCos Hiperface type — this gives position feedback on power-up without a homing cycle, and the SinCos track provides high-resolution velocity feedback for tight servo loop tuning. The torque constant is 2.78 N.m/A at 120 °C, and the back EMF constant is 193 V/krpm at 20 °C. Stator resistance is 5.3 Ohm and stator inductance is 88.55 mH. The maximum RMS current is 10.8 A. These values set the current-loop tuning gains and the voltage demand from the drive at high speed. ## Holding brake and mechanical envelope Integral holding brake rated at 23 N.m holding torque — sufficient to hold a vertical axis load or prevent shaft rotation when the drive is disabled. The brake is spring-applied, power-off engaged, so it fails safe on power loss. Motor flange size is 140 mm (5.5 in) with an international standard flange mount. Overall length is 255.5 mm (10.06 in). Shaft diameter is 24 mm with a parallel key and a shaft length of 50 mm. Maximum mechanical speed is 4000 rpm. IP65 rated on the motor body and shaft bushing, IP67 on the housing — suitable for washdown environments and dusty industrial floors. Cooling is by natural convection; no external fan or coolant required.","metaTitle":"Schneider Electric SH31401M12F1200 Servo Motor with Brake","metaDescription":"Schneider Electric SH31401M12F1200 SH3 servo motor, 1.7 kW continuous, 1500 rpm at 400 V three-phase, absolute multiturn SinCos Hiperface encoder, holding","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"10.06 in (255.5 mm)","Key width":"0.3 in (8 mm)","Shaft end":"Parallel key","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"With","Nominal speed":"375 rpm 115 V single phase 750 rpm 230 V single phase 1500 rpm 400 V three phase 1800 rpm 480 V three phase","Rotor inertia":"9.21 kg.cm²","Holding torque":"203.6 lbf.in (23 N.m)","Nominal torque":"97.4 lbf.in (11 N.m) 115 V single phase 96.92 lbf.in (10.95 N.m) 230 V single phase 93.8 lbf.in (10.6 N.m) 400 V three phase 92.05 lbf.in (10.4 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"2.78 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"1700 W","Mounting Support":"International standard flange","Sizing reference":"SH31401M","Back emf constant":"193 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"239.0 lbf.in (27 N.m) 115...480 V three phase","Stator inductance":"88.55 mH","Stator resistance":"5.3 Ohm","Maximum current Irms":"10.8 A","Nominal output power":"430 W 115 V single phase 860 W 230 V single phase 1670 W 400 V three phase 1960 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":"98.2 lbf.in (11.1 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":"1930 N 1000 rpm 1530 N 2000 rpm 1340 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"4 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/f4979fd64412fcb1ec8d3ecddb60a52d.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31401M12F1200/sh3-servomotor-140mm-1-stack-high-torque-keyed-shaft-sincos-multiturn-128-brake-straight-ip65-67/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M12F1200/alternatives.json"},"ai":{"faq":[{"question":"What encoder type does SH31401M12F1200 use?","answer":"Absolute multiturn SinCos Hiperface encoder.
