The 140 mm flange and integrated-drive form factor place it as a mid-frame PacDrive 3 axis — sized for machine builders who want the drive electronics co-located with the motor rather than in a separate cabinet. Lifecycle status is recorded as current by the manufacturer, so PacDrive 3 ILM is not a phase-out line at this writing — any substitution onto a non-Schneider equivalent would need a deviation request against the customer AML rather than being treated as a routine alternate. ## Torque, speed and current envelope Continuous torque is 4.6 N.m nominal (40.7 lbf.in) and 7.5 N.m continuous stall, with a peak stall of 27 N.m for acceleration margin — sizing the load inertia against peak stall rather than nominal is what keeps the drive out of the current-limit foldback region during index moves. Nominal mechanical output is 1450 W at 3000 rpm nominal speed, with line-rated current of 2.9 A and a maximum Irms of 18.8 A available transiently — the 4.7 A continuous stall current versus the 2.9 A nominal figure confirms the motor is thermally framed around its rated operating point rather than stall. ## Motor electrical constants and feedback Back-EMF constant is 108 V/krpm at 20 °C and torque constant is 1.6 N.m/A at 120 °C — the torque constant figure is published at the operating hotspot, so the 20 °C-to-120 °C delta has to be accounted for in any cold-start torque trim. Stator resistance is 1.81 Ohm phase-to-phase at 20 °C and stator inductance 19.1 mH phase-to-phase at 20 °C, with the phase-to-neutral figures published at 120 °C — those numbers feed the drive's current-loop tuning and the I²R loss budget at sustained duty. Position feedback is an absolute single-turn SinCos Hiperface device with 128 periods of resolution, so the absolute position is retained through power cycles without a homing routine on every restart — important on machines where the operator expects the axis to resume at the last commanded position. ## Mechanical envelope, shaft and mounting Flange size is 140 mm (5.5 in) with a 254 mm (10 in) body length, a 24 mm (0.9 in) keyed shaft 50 mm long, and no brake and no second shaft end — the keyed-only configuration means any holding-torque requirement on a vertical axis has to come from the drive's regenerative stop rather than a fail-safe mechanical brake. Mounting is an international standard flange with four 11 mm mounting holes and a 130 mm centring collar 3.5 mm deep — for machine builders, that footprint matches the standard IEC 140-frame bolt pattern, so no adapter plate is needed when replacing another 140-frame servo on a rebuild. ## Shaft loading, thermal and sealing Maximum radial force Fr is rated 2210 N at 1000 rpm, derating to 1760 N at 2000 rpm and 1530 N at 3000 rpm — for a belt or pinion drive the higher end of the speed range is what actually sets the bearing-life budget, so the 1530 N figure at 3000 rpm is the one that governs a directly-coupled application running at nominal speed. Axial load Fa is limited to 0.2 × Fr, and cooling is natural convection rather than forced air — vertical or horizontal mountings with restricted airflow around the housing need a thermal verification, because the absence of a fan means the housing has to dissipate the full I²R loss through the flange and free convection. ## Sourcing posture for PacDrive 3 ILM The part is recorded at current; there is no L*-entry successor or phase-out notice on file. For contract-manufacturing builds, that means it stays on the customer's approved-vendor list without a deviation — quoting to order against the BOM through independent distribution keeps the build on the AML until a future EOL is published.","metaTitle":"Schneider Electric ILM1401P31A0000 Servo Motor, 4.6 N.m","metaDescription":"Schneider Electric ILM1401P31A0000 PacDrive 3 ILM servo motor, 4.6 N.m nominal, 1450 W, IP65, currently produced.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Drives"],"specifications":{"title":"ILM1401P31A0000","Length":"10 in (254 mm)","Category":"US1PC5218351","Key width":"1.6 in (40 mm)","Shaft end":"Keyed","description":"ILM integrated drive, 140mm, 1 stack, keyed Shaft, IP65, SinCos Singleturn 128, no Brake","Second shaft":"Without second shaft end","Shaft length":"2.0 in (50 mm)","Feedback type":"Absolute single turn SinCos Hiperface","Holding brake":"Without","Nominal speed":"3000 rpm","Rotor inertia":"7.41 kg.cm²","Nominal torque":"40.7 lbf.in (4.6 N.m)","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.6 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Mounting Support":"International standard flange","Range of Product":"PacDrive 3","Back emf constant":"108 V/krpm 68 °F (20 °C)","Device short name":"ILM","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"239.0 lbf.in (27 N.m)","Stator inductance":"19.1 mH 68 °F (20 °C) Ph/Ph 9.55 mH 248 °F (120 °C) Ph/N","Stator resistance":"1.81 Ohm 68 °F (20 °C) Ph/Ph 1.26 Ohm 248 °F (120 °C) Ph/N","Line Rated Current":"2.9 A","Maximum current Irms":"18.8 A","Nominal Output Power":"1450 W","Centring collar depth":"0.1 in (3.5 mm)","Nbr. of units in pkg.":"1","Number of motor poles":"10","Maximum axial force Fa":"0.2 x Fr","Number of motor stacks":"1","Continuous stall torque":"66.4 lbf.in (7.5 N.m)","IP Degree of Protection":"IP65","Maximum radial force Fr":"2210 N 1000 rpm 1760 N 2000 rpm 1530 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"4.7 A","Number of mounting holes":"4","Product or Component Type":"Servo motor integrated drive","Speed feedback resolution":"128 periods","[Us] rated supply voltage":"250...700 V","Circle diameter of the mounting holes":"6.5 in (165 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/4f2c129bb8ddbc3afddcc738308d25c5.pdf","sourceUrl":"https://www.se.com/us/en/product/ILM1401P31A0000/ilm-integrated-drive-140mm-1-stack-keyed-shaft-ip65-sincos-singleturn-128-no-brake/"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the ILM1401P31A0000 in the Servo Drives family?","answer":"No alternate MPN is named in the record for this order code, so a like-for-like pin-compatible second source within the PacDrive 3 ILM family is not on file.
