The holding brake holds 23 N.m (203.6 lbf.in) — enough to lock a vertical load on a Z-axis when the drive is disabled, without a separate mechanical brake resistor. Rated speed shifts with supply voltage: 1500 rpm at 400 V three-phase, 1800 rpm at 480 V three-phase, and derated to 750 rpm at 230 V single-phase or 375 rpm at 115 V single-phase. Nominal torque stays near 10.6 N.m across the three-phase range. Encoder is an absolute single-turn SinCos Hiperface — no homing sequence on power-up, the controller reads position immediately. Saves a full minute per startup on multi-axis lines. ## IP rating and mechanical interface IP65 rating on the motor body with the shaft bushing and seal ring installed per IEC 60034-5 — handles washdown spray in food or packaging lines, but the shaft bushing without the seal ring drops to IP54, so check the seal kit at install. International standard flange, 140 mm (5.5 in) square, centring collar 130 mm diameter, four M11 mounting holes on a 165 mm bolt circle — bolts directly to a standard IEC frame mount without an adapter plate. Shaft is 24 mm diameter with a parallel key, 50 mm shaft length, 8 mm key width — mates with standard metric couplings and pulleys; no special shaft machining needed. ## Electrical parameters for drive tuning Stator resistance 5.3 Ohm, inductance 88.55 mH — these set the electrical time constant for the current loop. The drive's auto-tuning routine needs these values; manual entry works if the drive doesn't support auto-tune on Hiperface. Torque constant 2.78 N.m/A at 120 °C copper temperature — use this to calculate the RMS current for a given load torque profile. Continuous stall current is 4 A; peak current limit is 10.8 A RMS. Back EMF constant is 193 V/krpm at 20 °C — at 1800 rpm the motor generates about 347 V line-to-line. The drive's DC bus must be high enough to overcome this voltage plus the IR drop at full load. Sourced through independent distribution channels. Not a stock-holding item — lead time varies with batch size. The SH31401M sizing reference is specific to this flange size, power level, and encoder type — a substitution requires re-evaluating the motor's mechanical and electrical fit.","metaTitle":"Schneider SH31401M11F1000 Servo Motor with Brake, 1.7 kW","metaDescription":"Schneider Electric SH31401M11F1000 servo motor with brake, 1.7 kW continuous, 23 Nm holding torque, absolute single-turn SinCos Hiperface encoder.","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 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":"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/9918c4d304c966eef64ff6678ef4a402.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31401M11F1000/sh3-servomotor-140mm-1-stack-high-torque-keyed-shaft-sincos-singleturn-128-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401M11F1000/alternatives.json"},"ai":{"faq":[{"question":"What is SH31401M11F1000's continuous power and holding brake torque?","answer":"Continuous power is 1.7 kW (1700 W) with natural convection cooling.
