It delivers 1930 W nominal output power when fed from a 400 V three-phase supply, with a nominal speed of 4000 rpm at that voltage. The speed-torque envelope shifts with the input voltage: at 230 V single-phase the nominal speed drops to 2000 rpm and nominal torque to 5.2 N·m; at 480 V three-phase the nominal speed rises to 4800 rpm with 4.4 N·m torque. This means the drive supply voltage directly sets the usable operating point — confirm the line voltage before committing the BOM. Continuous stall torque is 5.8 N·m across the 115–480 V three-phase range, with a peak stall torque of 18.3 N·m. The peak-to-continuous ratio of about 3:1 supports aggressive acceleration profiles, but the natural convection cooling (no fan) means sustained high-torque duty cycles will thermally saturate the 130 °C copper hot limit. ## Shaft, flange, and coupling fit — 19 mm keyed shaft, 100 mm flange The motor carries a 19 mm diameter shaft with a 6 mm parallel keyway, 40 mm shaft length, and 3.5 mm centring collar depth. The flange is the international standard 100 mm (3.9 in) pattern — this mates directly with standard SH3 gearboxes and mounting brackets without adapter plates. Maximum radial force at the shaft is 2420 N at 1000 rpm, derating to 1670 N at 3000 rpm. Axial force limit is 300 N. These set the coupling selection — an overhung load or belt drive must stay within the speed-dependent radial envelope to avoid bearing preload failure. ## Encoder, connections, and environmental sealing The absolute single-turn encoder uses Hiperface DSL — a digital serial link protocol over a single pair, carrying position and temperature data. No battery backup needed for single-turn absolute position within one revolution. The motor provides both a straight connector and a quicklock rotatable right-angled connector for the power and feedback cabling. IP65 on the motor body per IEC 60034-5, but the shaft bushing drops to IP54 when the shaft seal ring is not fitted. In washdown or coolant-mist environments, fit the optional shaft seal ring to maintain the full IP65 rating at the shaft exit. The holding brake delivers 9 N·m holding torque and draws 12 W pull-in power. This is a spring-applied, electrically released brake — power-off the brake coil to engage. The 12 W DC supply must be sized separately from the motor drive; a shared 24 VDC bus is typical, but confirm the brake release voltage matches the control voltage. ## Electrical parameters for drive tuning and thermal protection Stator resistance is 2.4 Ω per phase, inductance 13.5 mH — these set the current-loop PI gains in the servo drive. The torque constant is 1.21 N·m/A at 120 °C copper temperature, and the back EMF constant is 77 V/krpm at 20 °C. At higher speeds the back EMF approaches the DC bus voltage; the drive must have sufficient voltage headroom to maintain current regulation. Maximum continuous current (Irms) is 17.1 A, with the same value as the 3-second peak current. The motor is wound for 4 poles. Continuous power is 1930 W at 400/480 V three-phase, dropping to 1090 W at 230 V single-phase. The natural convection cooling limits the thermal time constant — oversize the drive's continuous current rating to at least 20 A for sustained operation near the peak torque region. The sizing reference SH31002P anchors the family — this is the 100 mm flange, 1930 W variant with brake and absolute encoder. If the application does not require the holding brake, the equivalent motor without brake shares the same winding and flange dimensions; the brake-less variant will have lower total inertia and a shorter overall length.","metaTitle":"Schneider Electric SH31002P1AF4000 Servo Motor with Brake","metaDescription":"Schneider Electric SH31002P1AF4000 SH3 servo motor with holding brake, 1930 W at 400 V three-phase, 2000-4800 rpm, absolute single-turn encoder.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","title":"SH31002P1AF4000","Length":"9.3 in (235.5 mm)","Inertia":"0.618 kg.cm² of brake 0.0 kg.cm² of motor","Category":"US1PC5218359","Key width":"0.2 in (6 mm)","Shaft end":"Parallel key","description":"SH3 servomotor, 100mm, 2 stacks, keyed Shaft, Singleturn DSL 18bit, Brake, OneMotorCable angular M23, IP54/65","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":"2.928 kg.cm²","Holding torque":"79.7 lbf.in (9 N.m)","Nominal torque":"46.02 lbf.in (5.2 N.m) 230 V single phase 40.7 lbf.in (4.6 N.m) 400 V three phase 38.9 lbf.in (4.4 N.m) 480 V three phase","Shaft diameter":"0.7 in (19 mm)","Torque constant":"1.21 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"1930 W","Mounting Support":"International standard flange","Sizing reference":"SH31002P","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":"162.0 lbf.in (18.3 N.m) 115...480 V three phase","Stator inductance":"13.5 mH","Stator resistance":"2.4 Ohm","Brake pull-in power":"12 W","Maximum current Irms":"17.1 A","Nominal output power":"1090 W 230 V single phase 1930 W 400 V three phase 1930 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Straight connector","Electrical connection":"quicklock rotatable right angled connector","Nbr. of units in pkg.":"1","Number of motor poles":"4.0","Maximum axial force Fa":"300 N","Output current 3s peak":"17.1 A","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"51.3 lbf.in (5.8 N.m) 115...480 V three phase","IP degree of protection":"IP65 motor: conforming to IEC 60034-5 IP54 shaft bushing without shaft seal ring: 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 (9.0 mm)","Centring collar diameter":"3.7 in (95 mm)","Continuous stall current":"4.8 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":"$1,751.76","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c717dd129bc77259e4bd84177a45e79e.pdf","sourceUrl":"https://www.se.com/us/en/product/SH31002P1AF4000/sh3-servomotor-100mm-2-stacks-keyed-shaft-singleturn-dsl-18bit-brake-onemotorcable-angular-m23-ip54-65/"},"ai":{"faq":[{"question":"What is the nominal output power of SH31002P1AF4000 at 400 V three-phase?","answer":"1930 W nominal output power at 400 V three-phase, with a nominal speed of 4000 rpm and nominal torque of 4.6 N·m."},{"question":"What encoder type does SH31002P1AF4000 use?","answer":"Absolute single-turn Hiperface DSL encoder — a digital serial link protocol over a single pair, providing position and temperature feedback without battery backup for single-turn absolute position."},{"question":"What is the holding brake torque on SH31002P1AF4000?","answer":"79.7 lbf·in (9 N·m) holding torque, spring-applied and electrically released, with a 12 W pull-in power requirement."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/SH31002P1AF4000","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/SH31002P1AF4000 when reusing this data.
