On 400 V three-phase it turns 1500 rpm; on 480 V three-phase it reaches 1800 rpm. If you only have single-phase 230 V available, it still runs — at 750 rpm. The nominal torque holds fairly steady across supply configurations: 10.6 Nm at 400 V three-phase, 10.4 Nm at 480 V three-phase. That means the motor can deliver consistent torque regardless of which voltage standard your site uses, as long as you account for the speed difference. Continuous power is rated at 1700 W, with peak stall torque reaching 27 Nm across the 115...480 V three-phase range. The continuous stall torque sits at 11.1 Nm — so the motor can hold position under load without overheating, as long as the drive current stays at or below the 4 A continuous stall current. ## Encoder feedback and position control The motor carries an absolute single-turn SinCos Hiperface encoder. Single-turn means it knows its position within one revolution on power-up — no homing sequence needed after a power cycle. The Hiperface protocol is common across Schneider drives and many third-party servo drives, so it mates cleanly with a Lexium 32 or similar drive without extra interface hardware. The back EMF constant is 193 V/krpm at 20 °C, and the torque constant is 2.78 Nm/A at 120 °C. These numbers matter when you're sizing the drive: the drive's DC bus voltage must be high enough to overcome the back EMF at top speed, and the current loop needs to supply the torque constant's demand at the required torque. ## Mounting and environmental fit The motor uses an international standard flange with a 140 mm flange size and a 130 mm centring collar. It bolts in with four 11 mm mounting holes on a standard pattern — no custom adapter plate needed. The shaft is 24 mm diameter, 50 mm long, smooth (no keyway), so the coupling or pulley clamps onto the shaft directly. IP65 protection on both the motor body and the shaft bushing means it handles washdown and dust without sealing modifications. The cooling is natural convection — no fan to fail or filter to clean, but you do need to keep the ambient air moving enough to carry the 1700 W heat away. The total length is 217.5 mm, so it fits inside a standard NEMA 4X enclosure if the gland plate is positioned right. ## Sourcing and lifecycle status No minimum order quantity beyond the standard package of one unit.","metaTitle":"Schneider Electric SH31401M01A2100 Servo Motor, 1.7 kW","metaDescription":"Schneider Electric SH31401M01A2100 SH3 servo motor, 1.7 kW continuous power, 11 Nm torque, absolute single-turn Hiperface encoder, IP65, active production","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 single turn 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":"Straight connector","Electrical connection":"rotatable right angled 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","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/9476b92da2a7b0096b9ce44d3b0fbcdc.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401M01A2100/sh3-servomotor-140mm-1-stack-high-torque-smooth-shaft-sincos-singleturn-128-no-brake-angular-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M01A2100/alternatives.json"},"ai":{"faq":[{"question":"What supply voltage and phase does this motor need?","answer":"The motor is a three-phase design.
