Nominal torque follows the same voltage dependency — 218.6 lbf·in (24.7 N·m) at 115 V single-phase, dropping to 80.5 lbf·in (9.1 N·m) at 480 V three-phase — so the drive voltage selection directly sets the available torque at rated speed. Continuous power is 4100 W, with nominal output power varying from 1940 W at 115 V single-phase up to 4050 W at 400 V three-phase. Peak stall torque reaches 798.3 lbf·in (90.2 N·m) across the 115–480 V three-phase range, giving a 3.2× torque overload margin above the continuous stall torque of 246.05 lbf·in (27.8 N·m). The integrated holding brake delivers 318.6 lbf·in (36 N·m) of holding torque — this is the static torque that keeps the load position when the drive is disabled, not a dynamic braking torque for deceleration. The absolute single-turn SinCos Hiperface encoder provides position feedback at power-up without a homing cycle, which matters for applications where the machine must resume operation after a power loss without referencing. Maximum mechanical speed is 4000 rpm, so the encoder and bearings are rated for overspeed margin above the 3600 rpm nominal at 480 V. ## Mounting and mechanical interface — flange, shaft, and force limits The motor mounts to an international standard flange with a 5.5 in (140 mm) flange size and a 5.1 in (130 mm) centring collar, matching the common B5 / IM B5 flange pattern for direct coupling to gearboxes or pulleys. The smooth shaft has a 0.9 in (24 mm) diameter and 2.0 in (50 mm) length, so the coupling or pulley bore must be machined for a keyless interference fit or a clamping bushing. Maximum radial force is 2420 N at 1000 rpm, derating to 1670 N at 3000 rpm — this sets the belt tension or overhung load limit and is a common failure mode if exceeded at higher speeds. Maximum axial force is 300 N; any thrust load from helical gears or fan impellers must stay below this to avoid bearing preload damage. ## Thermal and electrical parameters — sizing the drive and cooling Cooling is by natural convection only — no integrated fan, so the motor relies on the machine frame or ambient airflow for heat rejection, and the continuous torque rating assumes free air circulation around the housing. Continuous stall current is 17.6 A, with a maximum RMS current of 61 A — the drive must be sized to supply the peak current during acceleration without saturating its current loop. Stator resistance is 0.4 Ω and stator inductance is 7.72 mH, giving an electrical time constant of about 19 ms — relevant for the drive's current regulator tuning and for estimating I²R losses at stall. ## Environmental protection and connection IP54 protection at the shaft bushing without the shaft seal ring, and IP65 on the motor body and with the shaft bushing seal ring installed — the difference is whether the shaft exit is sealed against low-pressure water jets. The electrical connection uses a straight connector, so the cable exits axially from the motor body — account for this in the cable routing and bend radius when mounting in a confined space.","metaTitle":"Schneider Electric SH31403P01F1000 Servo Motor with Brake","metaDescription":"Schneider Electric SH31403P01F1000 servo motor with holding brake, 4.1 kW continuous, absolute single-turn Hiperface encoder, IP54/IP65.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"14.4 in (365.5 mm)","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":"23.44 kg.cm²","Holding torque":"318.6 lbf.in (36 N.m)","Nominal torque":"218.6 lbf.in (24.7 N.m) 115 V single phase 187.6 lbf.in (21.2 N.m) 230 V single phase 114.2 lbf.in (12.9 N.m) 400 V three phase 80.5 lbf.in (9.1 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.58 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"4100 W","Mounting Support":"International standard flange","Sizing reference":"SH31403P","Back emf constant":"105 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"798.3 lbf.in (90.2 N.m) 115...480 V three phase","Stator inductance":"7.72 mH","Stator resistance":"0.4 Ohm","Maximum current Irms":"61 A","Nominal output power":"1940 W 115 V single phase 3330 W 230 V single phase 4050 W 400 V three phase 3430 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":"246.05 lbf.in (27.8 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":"2420 N 1000 rpm 1920 N 2000 rpm 1670 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"17.6 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/44fa696487a9e9e2acff72df4024ad11.pdf","sourceUrl":"https://www.se.com/ca/en/product/SH31403P01F1000/sh3-servomotor-140mm-3-stacks-smooth-shaft-sincos-singleturn-128-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31403P01F1000/alternatives.json"},"ai":{"faq":[{"question":"What is the holding torque of the brake on SH31403P01F1000?","answer":"The integrated holding brake delivers 318.6 lbf·in (36 N·m) of static holding torque, which is the torque that keeps the load position when the drive is disabled."},{"question":"What encoder type does SH31403P01F1000 use?","answer":"It uses an absolute single-turn SinCos Hiperface encoder, which provides position feedback at power-up without requiring a homing cycle."},{"question":"What is the maximum mechanical speed of SH31403P01F1000?","answer":"The maximum mechanical speed is 4000 rpm, providing overspeed margin above the 3600 rpm nominal speed at 480 V three-phase."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH31403P01F1000","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/SH31403P01F1000 when reusing this data.
