Continuous power is 2400 W, with a continuous stall torque of 8 N.m (70.8 lbf.in) across the 115...480 V three-phase range, and a peak stall torque of 28.3 N.m (250.5 lbf.in) — the peak figure governs acceleration and emergency stop sizing, not the steady-state duty. ## Encoder, feedback, and integration constraints The motor ships with an absolute single-turn Hiperface DSL encoder — this is a digital serial-link feedback protocol that carries position and temperature data over a single pair, reducing cable count compared to incremental encoders with separate commutation tracks. Electrical connection is via a rotatable right-angled connector plus a quicklock straight connector — the rotatable option lets the cable exit in any of four orientations, which matters when the motor is mounted in a tight cabinet corner where a fixed connector would force a cable bend radius violation. ## Speed, torque, and voltage dependence Nominal speed varies with supply voltage: 2000 rpm at 230 V single-phase, 4000 rpm at 400 V three-phase, and 4800 rpm at 480 V three-phase — the motor's torque-speed curve is voltage-limited, so a 480 V line delivers higher top speed but the same continuous torque rating at that speed. Nominal output power also shifts: 1470 W at 230 V single-phase, 2390 W at both 400 V and 480 V three-phase — the 230 V single-phase figure is roughly 60 % of the three-phase rating, which affects machine cycle time if the line supply is single-phase only. Torque constant is 1.22 N.m/A at 120 °C (248 °F) copper temperature — this is the hot rating, not the 20 °C cold value, so the drive's current limit must be set to deliver the required torque at operating temperature, not at startup. ## Mechanical interface and mounting The motor uses an international standard flange with a 100 mm (3.9 in) flange size, a centring collar diameter of 95 mm (3.7 in) and depth of 3.5 mm (0.1 in), and four mounting holes of 9.0 mm (0.4 in) diameter — this matches the IEC 72-1 standard for frame size 100, so it bolts directly to common gearbox and machine interfaces without an adapter plate. Shaft dimensions: 19 mm (0.7 in) diameter, 40 mm (1.6 in) length, with a parallel key and a 6 mm (0.2 in) key width — the parallel key transmits torque to the load coupling; the keyway depth and fit class should be verified against the mating hub to avoid fretting under reversing loads. Maximum radial force Fr is 4500 N at 1000 rpm, 3570 N at 2000 rpm, and 3120 N at 3000 rpm — the bearing load limit drops with speed, so a belt-driven application at 3000 rpm must keep the belt tension below 3120 N to avoid premature bearing failure. Maximum axial force Fa is 740 N — this limits the thrust load from a helical gear or a leadscrew; exceeding it pushes the rotor against the bearing shield and increases friction or causes seizure. No official successor or cross-reference is recorded — this is the current production part number.","metaTitle":"Schneider Electric SH31003P1AF3100 Servo Motor with Brake","metaDescription":"Schneider Electric SH31003P1AF3100 servo motor with brake, 2.4 kW continuous power, 2000 rpm nominal speed, IP65, absolute single-turn Hiperface DSL encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"10.7 in (271.5 mm)","Category":"US1PC5218359","Key width":"0.2 in (6 mm)","Shaft end":"Parallel key","Encoder type":"Absolute single turn Hiperface DSL","Shaft length":"1.6 in (40 mm)","Holding brake":"With","Nominal speed":"2000 rpm 230 V single phase 4000 rpm 400 V three phase 4800 rpm 480 V three phase","Rotor inertia":"3.838 kg.cm²","Holding torque":"79.7 lbf.in (9 N.m)","Nominal torque":"62.0 lbf.in (7 N.m) 230 V single phase 50.4 lbf.in (5.7 N.m) 400 V three phase 45.1 lbf.in (5.1 N.m) 480 V three phase","Shaft diameter":"0.7 in (19 mm)","Torque constant":"1.22 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"2400 W","Mounting Support":"International standard flange","Sizing reference":"SH31003P","Back emf constant":"77 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"3.9 in (100 mm)","Peak stall torque":"250.5 lbf.in (28.3 N.m) 115...480 V three phase","Stator inductance":"9.4 mH","Stator resistance":"1.43 Ohm","Brake pull-in power":"18 W","Maximum current Irms":"28.3 A","Nominal output power":"1470 W 230 V single phase 2390 W 400 V three phase 2390 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Rotatable right angled connector","Electrical connection":"quicklock straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"4","Maximum axial force Fa":"740 N","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"70.8 lbf.in (8 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","Maximum radial force Fr":"3570 N 2000 rpm 3120 N 3000 rpm 4500 N 1000 rpm","Mounting holes diameter":"0.4 in (9.0 mm)","Centring collar diameter":"3.7 in (95 mm)","Continuous stall current":"6.6 A","Maximum mechanical speed":"6000 rpm","Network number of phases":"3","Number of mounting holes":"4","Product or Component Type":"Servo motor","Speed feedback resolution":"262144 points/turn","[Us] rated supply voltage":"115...480 V","Circle diameter of the mounting holes":"4.5 in (115 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/82184ff69a401d8847e7ebeb11428d34.pdf","sourceUrl":"https://www.se.com/be/en/product/SH31003P1AF3100/sh3-servomotor-100mm-3-stacks-keyed-shaft-singleturn-dsl-18bit-brake-onemotorcable-straight-m23-ip65-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31003P1AF3100/alternatives.json"},"ai":{"faq":[{"question":"Who supplies SH31003P1AF3100 and how is it quoted for volume purchases?","answer":"We supply this servo motor through independent distribution channels."},{"question":"What is the closest pin-compatible alternative to SH31003P1AF3100 in this Servo Motors with Brake family?","answer":"No official pin-compatible alternative or cross-reference is recorded in the Schneider Electric documentation for this part.
