The brake delivers 23 N·m holding torque — sufficient to hold a suspended load without power to the motor, meeting safety requirements for Z-axis stops. Rated continuous power is 2900 W, with a maximum mechanical speed of 4000 rpm. The motor is naturally convection cooled — no external fan or forced-air ducting required, simplifying panel layout and reducing maintenance points. ## Speed-torque envelope and voltage dependency Nominal speed varies with supply: 750 rpm at 115 V single-phase, 1500 rpm at 230 V single-phase, 3000 rpm at 400 V three-phase, and 3600 rpm at 480 V three-phase. This voltage-dependent speed profile means the motor's rated output torque also shifts — nominal torque at 400 V three-phase is 9.2 N·m, dropping to 8.4 N·m at 480 V three-phase. Sizing must account for the actual supply voltage at the installation. Peak stall torque is 27 N·m across the 115–480 V three-phase range, giving a 2.4× torque margin over the nominal 400 V rating for acceleration and overload events. Continuous stall torque is 11.1 N·m at the same voltage range, with a continuous stall current of 7.8 A. Maximum RMS current is 20.8 A — this sets the drive's continuous current rating requirement. The torque constant is 1.43 N·m/A at 120 °C copper temperature, so the drive must supply at least 7.8 A to reach continuous stall torque and up to 20.8 A for peak torque. ## Encoder, mounting, and environmental sealing The motor carries an absolute single-turn SinCos Hiperface encoder — position is retained at power-off, so homing sequences are not required after a power cycle. The encoder provides sine/cosine analog tracks plus a digital commutation channel, compatible with Schneider's Lexium drive family and third-party Hiperface-capable drives. Mounting uses an international standard flange with a 140 mm flange size and 130 mm centring collar diameter. The overall length is 255.5 mm with a smooth 24 mm shaft extending 50 mm. Shaft bushing without shaft seal ring gives IP54; with the shaft seal ring fitted, the motor achieves IP65 — suitable for washdown or dusty environments per IEC 60034-5. ## Bearing load limits and thermal constraints Maximum radial force Fr is speed-dependent: 1930 N at 1000 rpm, 1530 N at 2000 rpm, 1340 N at 3000 rpm. Maximum axial force Fa is 300 N. These limits govern belt-drive or direct-coupling selections — exceeding them reduces bearing life below the motor's design target. Stator resistance is 1.41 Ω and inductance is 23.72 mH — these values affect the drive's current-loop tuning and the motor's thermal time constant. Copper temperature hot rating is 130 °C; the back EMF constant is 100 V/krpm at 20 °C, which sets the voltage-speed operating line for the drive's DC bus.","metaTitle":"Schneider Electric SH31401P01F1000 Servo Motor with Brake","metaDescription":"Schneider Electric SH31401P01F1000 servo motor with brake, 2.9 kW continuous power, 4000 rpm max speed, 23 N·m holding brake.","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)","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":"With","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":"9.21 kg.cm²","Holding torque":"203.6 lbf.in (23 N.m)","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/eb3eb092de7a7fe60744cff62d3efd6d.pdf","sourceUrl":"https://www.se.com/vn/en/product/SH31401P01F1000/sh3-servomotor-140mm-1-stack-smooth-shaft-sincos-singleturn-128-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31401P01F1000/alternatives.json"},"ai":{"faq":[{"question":"What supply voltage and phase does this motor require?","answer":"The SH31401P01F1000 is a three-phase motor.
