At 400 V three-phase the nominal speed is 3000 rpm; at 480 V three-phase it reaches 3600 rpm. Single-phase 115 V or 230 V inputs drop the nominal speed to 750 rpm and 1500 rpm respectively, so the drive must match the available line voltage to hit the target speed. Nominal torque also shifts with the supply. At 400 V three-phase the motor delivers 9.2 N.m; at 480 V three-phase it drops to 8.4 N.m. The torque constant is 1.43 N.m/A at 120 °C copper temperature, which sets the current loop gain in the servo drive. ## Encoder feedback and absolute positioning The absolute single-turn SinCos Hiperface encoder gives position feedback at power-up without a homing cycle — the drive reads the absolute position from the encoder's single-turn count. This matters for applications where the machine must resume from the last known position after a power cycle, like a rotary axis or a pick-and-place gantry. The back EMF constant is 100 V/krpm at 20 °C. During commissioning, the drive's velocity loop tuning must account for this to avoid overshoot on deceleration. The stator inductance is 23.72 mH and resistance is 1.41 Ohm, which defines the electrical time constant and the current regulator bandwidth. ## Torque envelope and thermal limits Cooling is natural convection, so no external fan or forced air is required. The continuous power rating is 2.9 kW, with nominal output power reaching 2.89 kW at 400 V three-phase and 3.17 kW at 480 V three-phase. The maximum mechanical speed is 4000 rpm, which is above the electrical speed at 480 V — the bearing and rotor balance limit, not the winding. ## Mounting, shaft, and ingress protection The motor flange size is 140 mm with a centring collar diameter of 130 mm and a depth of 3.5 mm — standard IEC mounting. The shaft is smooth, 24 mm diameter by 50 mm long, so a shaft coupling with a clamping hub is required — no keyway. Overall length is 217.5 mm. Ingress protection is IP54 at the shaft bushing without a shaft seal ring, or IP65 at the motor body and shaft bushing with the seal ring fitted. For washdown environments, specify the shaft seal — without it, moisture can enter along the shaft. Maximum radial force is 1930 N at 1000 rpm, derating to 1340 N at 3000 rpm; maximum axial force is 300 N.","metaTitle":"Schneider Electric SH31401P01A1000 Servo Motor, 2.9 kW","metaDescription":"Schneider Electric SH31401P01A1000 SH3 servo motor, 2.9 kW continuous at 400 V three-phase, 10.95 N.m nominal torque, absolute 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":"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":"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":"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/d26c2c358948aaa63a8c73d66f19151a.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31401P01A1000/servo-motor-sh3-140-111nmnokeysinglenobrakestr-connip54-ip654k-rpm/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401P01A1000/alternatives.json"},"ai":{"faq":[{"question":"What supply voltage and phase does SH31401P01A1000 require?","answer":"The motor is wound for three-phase operation.
