Nominal torque sits at 8.3 N.m at 1500 rpm, which translates to a 1300 W mechanical output point. Above that speed the constant-power region begins; the back-EMF constant of 175 V/krpm is the figure that sets how hard the upstream PacDrive controller has to push the DC bus to reach rated speed. Continuous current is 3.2 A with a peak Irms of 14.6 A — the peak-to-continuous ratio is the same 3× envelope the torque rating shows, confirming the drive can over-current for short bursts without tripping the protection. ## Feedback, winding and the electrical side Feedback is single-turn SinCos Hiperface with 128 periods per turn, which is the standard PacDrive absolute encoder profile — position is retained after power-down without a battery, and the controller hands it multi-turn info from the drive-side gearing when needed. Stator resistance is 4.58 Ohm phase-to-phase at 20 °C, dropping to 3.18 Ohm phase-to-neutral at the 120 °C hot-spot; inductance shows the same 2:1 ratio (50 mH Ph/Ph vs 25 mH Ph/N at the same temperatures). These numbers are what the drive uses to model the torque loop — they are the constants the commutation algorithm depends on, not selection parameters for the buyer. Torque constant is 2.65 N.m/A referenced at the 120 °C winding hot-spot, so a 3.2 A continuous stall produces the rated 8.5 N.m — the figures tie out internally and confirm the motor is being driven within its thermal envelope, not just its current envelope. ## Flange, shaft and IP65 — mounting the old footprint Mounting is an international-standard flange on a 140 mm motor frame with a 130 mm centring collar and four 11 mm holes — a common B5-style footprint that often drops into the same machine base as the older 140-frame servos it replaces. The keyed shaft is 24 mm diameter by 50 mm long with a 1.6 in (40 mm) keyway — a heavy-duty output suitable for belt or pinion coupling without a second shaft end protruding. Maximum radial load is 2210 N at 1000 rpm derating to 1760 N at 2000 rpm, and axial load is capped at 0.2 × Fr, so the coupling choice matters more than the bolt pattern. IP65 sealing at the housing means the body tolerates hose-down and dusty cells but is not rated for submersion — fine for the typical plant floor, not for a wet-process washdown. Cooling is natural convection, so the motor must be mounted with adequate clearance around the body and not blanketed inside a sealed enclosure. ## What the absence of a holding brake means here This build ships without a holding brake and without a second shaft end, so vertical-axis applications that need a fail-safe park position will need an external brake or a different motor variant — the ILM1401M31A0000 is sized for horizontal motion or for systems that hold position through the controller's torque.","metaTitle":"Schneider Electric ILM1401M31A0000 servo motor, 8.5 N.m","metaDescription":"Schneider Electric ILM1401M31A0000 PacDrive 3 ILM servo motor, 1300 W, 8.3 N.m nominal, IP65 flange, sourced to order against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Drives"],"specifications":{"title":"ILM1401M31A0000","Length":"10 in (254 mm)","Category":"US1PC5218351","Key width":"1.6 in (40 mm)","Shaft end":"Keyed","description":"ILM integrated drive, 140mm, 1 stack, high Torque, 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":"1500 rpm","Rotor inertia":"7.41 kg.cm²","Nominal torque":"73.5 lbf.in (8.3 N.m)","Shaft diameter":"0.9 in (24 mm)","Torque constant":"2.65 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":"175 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":"50 mH 68 °F (20 °C) Ph/Ph 25 mH 248 °F (120 °C) Ph/N","Stator resistance":"4.58 Ohm 68 °F (20 °C) Ph/Ph 3.18 Ohm 248 °F (120 °C) Ph/N","Line Rated Current":"3.15 A","Maximum current Irms":"14.6 A","Nominal Output Power":"1300 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":"75.2 lbf.in (8.5 N.m)","IP Degree of Protection":"IP65","Maximum radial force Fr":"2210 N 1000 rpm 1760 N 2000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"3.2 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/77ec87d454bad06dfcf3b3a59f24c565.pdf","sourceUrl":"https://www.se.com/ie/en/product/ILM1401M31A0000/ilm-integrated-drive-140mm-1-stack-high-torque-keyed-shaft-ip65-sincos-singleturn-128-no-brake/"},"ai":{"faq":[{"question":"Who supplies ILM1401M31A0000 and how is it quoted for volume purchases?","answer":"Independent industrial-automation distribution sources the ILM1401M31A0000 to order.
