Nominal speed varies with supply: 375 rpm at 115 V single phase, 750 rpm at 230 V single phase, 1500 rpm at 400 V three phase, and 1800 rpm at 480 V three phase. Maximum mechanical speed is 4000 rpm, so the motor can overspeed above the nominal point if the drive and load allow it. Peak stall torque is 27 Nm across the 115–480 V three-phase range, giving a 2.4× overload margin above the continuous stall torque of 11.1 Nm. This headroom handles acceleration and intermittent loads without saturating the magnetic circuit. ## Encoder 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, which matters for applications that must resume from the last known position after a power loss. IP54 on the shaft bushing without a shaft seal ring, IP65 on the motor body and shaft bushing with the seal ring fitted (per IEC 60034-5). The IP65 rating means the motor withstands hose-down cleaning in food or washdown environments, but the shaft seal ring must be present to keep water out of the bearing cavity. ## Mounting and mechanical interface International standard flange, 140 mm flange size, with a 130 mm centring collar and 11 mm mounting holes. The shaft is 24 mm diameter, 50 mm long, smooth (no keyway), so the coupling or pulley must use a clamping or friction fit — no key to transmit torque. Electrical connection via a rotatable right-angled connector or a straight connector — the rotatable option helps route the cable in tight cabinets without bending the cable beyond its minimum radius. Natural convection cooling means no fan, so the motor relies on the mounting surface and ambient airflow for heat rejection. The SH31401M sizing reference and SH3 device short name identify the frame and winding variant — confirm the mating drive's current rating and encoder interface (Hiperface) before specifying.","metaTitle":"Schneider Electric SH31401M02A1000 Servo Motor, 1700 W","metaDescription":"Schneider Electric SH31401M02A1000 SH3 servo motor, 1700 W continuous power, 11 Nm nominal torque, absolute multiturn Hiperface encoder, IP54/IP65, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"8.6 in (217.5 mm)","Key width":"0.3 in (8 mm)","Shaft end":"Smooth shaft","Encoder type":"Absolute multiturn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","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":"7.41 kg.cm²","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":"Rotatable right angled 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":"IP54 shaft bushing without shaft seal ring: conforming to IEC 60034-5 IP65 motor: conforming to IEC 60034-5 IP65 shaft bushing: 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/7ae472cdca213ce80d8066ac6d2b55dc.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401M02A1000/sh3-servomotor-140mm-1-stack-high-torque-smooth-shaft-sincos-multiturn-128-no-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M02A1000/alternatives.json"},"ai":{"faq":[{"question":"What encoder type does SH31401M02A1000 use?","answer":"It uses an absolute multiturn SinCos Hiperface encoder.
