Nominal torque follows the same pattern: 9.2 N·m at 400 V three-phase, 8.4 N·m at 480 V three-phase. The 400 V rating is the one to size against for standard European line voltages; the 480 V figure applies in North American 480 VAC installations. Continuous power at 400 V three-phase is 2890 W, and the continuous stall torque across the 115–480 V three-phase range is 11.1 N·m. That stall torque is the figure that governs holding torque at zero speed — relevant for positioning applications where the motor holds a load at rest. ## Encoder and feedback — absolute single-turn SinCos Hiperface The absolute single-turn SinCos Hiperface encoder reports position within one revolution on power-up, no homing cycle needed. The SinCos analog track gives interpolated position for smooth velocity control down to standstill — the drive reads the sine/cosine signals for sub-division beyond the raw encoder resolution. This encoder type mates with Schneider Lexium 32 and 62 drive families natively, and with third-party drives that support the Hiperface protocol. The straight connector is a standard industrial round connector — no special cable assembly required. ## Mechanical fit — flange, shaft, and mounting The motor flange is 140 mm (5.5 in) with a 130 mm centring collar and 11 mm mounting holes — this is the IEC standard B5 flange pattern. The smooth shaft is 24 mm diameter by 50 mm long, with a 3.5 mm centring collar depth. No keyway: the smooth shaft means the load coupling must use a clamping or friction-fit method. Maximum radial force at the shaft is 1930 N at 1000 rpm, dropping to 1340 N at 3000 rpm. Maximum axial force is 300 N. These limits govern bearing life when the load applies overhung or thrust loads — a belt drive or helical gearbox must stay within these to avoid premature bearing failure. ## Thermal and electrical parameters Cooling is natural convection — no fan, so the motor relies on its own surface area and the mounting flange for heat dissipation. The hot-spot copper temperature is rated at 130 °C. In a confined panel or enclosed mounting, the ambient temperature around the motor must stay within the motor's operating range to avoid thermal trip. Stator resistance is 1.41 Ω and inductance is 23.72 mH — these set the electrical time constant and influence the drive's current-loop tuning. The torque constant is 1.43 N·m/A at 120 °C copper temperature, and the back-EMF constant is 100 V/krpm at 20 °C. These constants let the drive calculate the motor's voltage demand at speed. Continuous stall current is 7.8 A; maximum RMS current is 20.8 A. The peak stall torque across the full voltage range is 27 N·m — that's the torque available for acceleration or for breaking a stuck load, limited by the drive's peak current capability. ## Environmental protection and lifecycle The motor body and shaft bushing are rated IP65 per IEC 60034-5; the housing is rated IP67. This means the motor withstands hose-directed water (IP65) and temporary immersion (IP67) — suitable for washdown areas in food processing or outdoor installations where the motor is not submerged continuously.","metaTitle":"Schneider Electric SH31401P01A1200 Servo Motor, 2.9 kW","metaDescription":"Schneider Electric SH31401P01A1200 servo motor, 2.9 kW continuous power, 400 V three-phase, 3000 rpm, absolute SinCos Hiperface encoder, IP65/IP67, smooth","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)","Category":"18359-PACDRIVE3 SERVO MOTORS","Shaft end":"Smooth shaft","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","Nominal speed":"750 rpm 115 V single phase 1500 rpm 230 V single phase 3000 rpm 400 V three phase 3600 rpm 480 V three phase","Rotor inertia":"7.41 kg.cm²","Nominal torque":"96.92 lbf.in (10.95 N.m) 115 V single phase 93.8 lbf.in (10.6 N.m) 230 V single phase 81.4 lbf.in (9.2 N.m) 400 V three phase 74.3 lbf.in (8.4 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.43 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"2900 W","Mounting Support":"International standard flange","Sizing reference":"SH31401P","Back emf constant":"100 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":"23.72 mH","Stator resistance":"1.41 Ohm","Maximum current Irms":"20.8 A","Nominal output power":"860 W 115 V single phase 1670 W 230 V single phase 2890 W 400 V three phase 3170 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":"7.8 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/de91e3568a2566a674527522a4db743b.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31401P01A1200/sh3-servomotor-140mm-1-stack-smooth-shaft-sincos-singleturn-128-no-brake-straight-ip65-67/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401P01A1200/alternatives.json"},"ai":{"faq":[{"question":"What supply voltages does SH31401P01A1200 run on?","answer":"The motor is three-phase and runs on 400 V three-phase (3000 rpm) or 480 V three-phase (3600 rpm).
