Natural convection cooling is the only thermal path on the unit, which keeps the cabinet clean of fans and ducting — but it also means the continuous torque rating assumes the mounting surface acts as a heatsink, and a stuffed enclosure will pull continuous torque down long before it trips the peak figure. ## Torque, speed, and what the 1300 W envelope actually means on the line Continuous stall torque lands at 8.5 N·m with a continuous stall current of 3.2 A and a line-rated current of 3.15 A, while peak stall torque reaches 27 N·m and the drive can deliver a maximum Irms of 14.6 A — that's roughly a 3× overload headroom for short accel/decel bursts on a conveyor index or a small press feed. Nominal torque is 8.3 N·m at the rated 1500 rpm, which lines up with the 1300 W nominal output power — pick a gearbox or pulley ratio off the 8.3 N·m figure for steady-state sizing, and reserve the 27 N·m peak only for short move profiles where duty cycle stays below the thermal ceiling. ## Feedback, brake, and shaft detail for the panel-builder Position feedback is an absolute single-turn SinCos Hiperface encoder, so the controller reads absolute shaft position on power-up with no homing routine — appropriate for indexed motion where losing position after an E-stop would cost a re-home cycle. A holding brake is fitted and rated 18 N·m holding torque, paired with a 24 mm untapped shaft and a 2.0 in (50 mm) shaft length with one keyway at 1.6 in (40 mm) width — there is no second shaft end, so any auxiliary encoder or hand-crank decoupler needs its own bracket. Maximum radial load is 2210 N at 1000 rpm, dropping to 1760 N at 2000 rpm, and maximum axial force is capped at 0.2 × Fr — a belt drive with too much pre-tension will eat the bearings long before the drive ever faults. ## Sealing, electrical constants, and what IP65 actually buys you IP65 sealing on the motor body suits washdown-adjacent areas and most outdoor enclosures, but it is not IP67 — high-pressure hot-water cleaning directly on the unit will eventually defeat the seal. Stator resistance reads 4.58 Ohm phase-to-phase at 20 °C and 3.18 Ohm phase-to-neutral at 120 °C, with stator inductance of 50 mH Ph/Ph at 20 °C and 25 mH Ph/N at 120 °C — these are the values to feed into a torque-loop or field-weakening model, and the temperature coefficient is significant enough that a cold-start tune will drift once the motor warms up.","metaTitle":"Schneider Electric ILM1401M21F0000 PacDrive 3 Servo Motor","metaDescription":"Schneider Electric ILM1401M21F0000 PacDrive 3 ILM integrated servo motor, 8.3 N·m nominal / 27 N·m peak, 24 mm shaft, IP65.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Drives"],"specifications":{"Length":"11.5 in (292 mm)","Category":"US1PC5218351","Key width":"1.6 in (40 mm)","Shaft end":"Untapped","Second shaft":"Without second shaft end","Shaft length":"2.0 in (50 mm)","Feedback type":"Absolute single turn SinCos Hiperface","Holding brake":"With","Nominal speed":"1500 rpm","Rotor inertia":"7.41 kg.cm²","Holding torque":"159.3 lbf.in (18 N.m) holding brake","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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/08a0fe6b8be4d54f975c98ca070bc64a.pdf","sourceUrl":"https://www.se.com/be/en/product/ILM1401M21F0000/ilm-integrated-drive-140mm-1-stack-high-torque-smooth-shaft-ip65-sincos-singleturn-128-brake/","alternativesUrl":"https://aoctrl.com/api/mcp/products/ILM1401M21F0000/alternatives.json"},"ai":{"faq":[{"question":"What is the listed length of the ILM1401M21F0000 on this servo drive line?","answer":"The ILM1401M21F0000 ships at 11.5 in (292 mm) end-to-end with a 140 mm flange and a 24 mm shaft, so verify the available cabinet depth and the shaft-to-coupling clearance before pulling the motor out of stock."},{"question":"What is the closest pin-compatible alternative to the ILM1401M21F0000 in this servo drive family?","answer":"The PacDrive 3 ILM family covers multiple lengths and brake/feedback combinations on the same 140 mm flange — the next size up or down will share the mounting pattern, but exact torque and inertia ratings differ.
