The SH31401M01F1200 is a three-phase servo motor from the SH3 family, and its speed-torque curve depends on what voltage you feed it. On 400 V three-phase, it delivers 1500 rpm nominal; on 480 V three-phase, 1800 rpm. Single-phase 115 V drops it to 375 rpm, and 230 V single-phase gives 750 rpm — so if you're wiring into a single-phase shop, you're trading speed for the same frame size. Continuous power is 1700 W, but the nominal output power shifts with the supply: 430 W on 115 V single-phase, 860 W on 230 V single-phase, 1670 W on 400 V three-phase, and 1960 W on 480 V three-phase. That means the motor is really built for three-phase duty — single-phase connections leave a lot of the copper on the table. Peak stall torque hits 27 Nm across the 115–480 V three-phase range, and continuous stall torque is 11.1 Nm. The holding brake is rated at 23 Nm — that's the number that matters for vertical-axis safety: if the drive loses power, the brake holds the load, not the motor magnets. ## Encoder feedback and mounting fit The encoder is an absolute single-turn SinCos Hiperface — that's a digital position feedback with analog sine/cosine tracks for interpolation. Single-turn means it knows its position within one revolution after power-up, but not the number of turns. Hiperface is a common protocol for drives from several manufacturers; the drive parameter set needs to match the encoder resolution and commutation offset. The motor flange is 140 mm (5.5 in) with a centring collar diameter of 130 mm and depth of 3.5 mm. Shaft is 24 mm diameter, 50 mm long, smooth (no keyway) — so the coupling or pulley clamps on with a friction lock. Key width is 8 mm if you add a key later, but as shipped it's a smooth shaft. The IP rating is IP65 on the motor body and shaft bushing, IP67 on the housing — meaning it handles washdown spray but not submersion. The sizing reference is SH31401M, which is the motor family this unit belongs to. The SH3 series covers a range of flange sizes and power ratings; this particular variant includes the holding brake and the Hiperface encoder. No direct pin-compatible alternative is listed — if you need a replacement, the BOM position should match this exact order code.","metaTitle":"Schneider Electric SH31401M01F1200 Servo Motor with Brake","metaDescription":"Schneider Electric SH31401M01F1200 SH3 servo motor, 1700 W continuous power, 23 Nm holding brake, absolute Hiperface encoder, IP65.","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":"Smooth shaft","Encoder type":"Absolute single turn 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/a4d618edf4c5f18e882f1ab343b4b9a3.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31401M01F1200/sh3-servomotor-140mm-1-stack-high-torque-smooth-shaft-sincos-singleturn-128-brake-straight-ip65-67/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M01F1200/alternatives.json"},"ai":{"faq":[{"question":"What is SH31401M01F1200's listed phase and length?","answer":"The motor is a three-phase design.
