It is rated 1100 W nominal output at 3000 rpm and 3.5 N.m continuous nominal torque, with a peak stall envelope of 28.3 N.m available for acceleration transients — a ratio of roughly 8× over nominal that the motion controller uses for short move profiles. ## Torque and current envelope that drives the sizing decision Peak Irms of 21.2 A is the thermal ceiling the drive enforces during acceleration; the winding constant of 1.61 N.m/A at 120 °C tells you the torque-per-amp slope shifts upward once the motor is hot, so the same current command produces slightly more torque at working temperature than at cold start. Back-EMF constant is 103 V/krpm at 20 °C, which sets the bus-voltage headroom: at the 3000 rpm nominal point the generated EMF is roughly 310 V, so a 400 V-class DC bus is required to retain regulation margin at top speed. ## Feedback, shaft, and mechanical load envelope Position feedback is Hiperface SinCos absolute single-turn at 128 periods per revolution — the absolute channel eliminates the homing move on power-up, which matters for any machine that has to be position-ready the moment the safety circuit closes. The shaft is 19 mm diameter, 40 mm long, with a 30 mm keyway and no second shaft end and no holding brake — that combination rules out any axis that needs a fail-safe spring-applied brake (a vertical unpowered load will coast), so the ILM1003P31A0000 is sized for horizontal or pre-balanced axes. Maximum radial load is 1050 N at 1000 rpm, dropping to 830 N at 2000 rpm and 730 N at 3000 rpm — bearing life is governed by the belt tension or pinion gear mesh reaction at the rated speed, so a high-ratio timing-belt drive should be checked against the 3000 rpm value rather than the headline figure. Axial load is permitted up to 0.2 × Fr, which is the limit when a coupling or a helical pinion is pushing along the shaft — anything beyond that needs a separate thrust bearing in the gearbox housing. ## Sealing, cooling, and cabinet integration Cooling is natural convection, so there is no fan to fail and no dust path into the rotor — the flip side is that continuous torque must be derated if the motor is enclosed in a heat-soaking cabinet, and the IP65 rating on the housing seals against water jets but assumes the cable gland is also torqued against its O-ring. The 100 mm flange with 95 mm centring collar and four M9 mounting holes drops into the standard IEC footprint — the rear-of-motor integrated drive adds length beyond a conventional servo of the same frame, so cabinet depth has to allow for the drive housing plus the bend radius of the hybrid cable to the PacDrive controller. ## Stator model for commissioning and drive tuning Stator resistance is 2.6 Ohm phase-to-phase at 20 °C (1.81 Ohm phase-to-neutral at 120 °C) and inductance is 15.6 mH phase-to-phase at 20 °C — these are the values the auto-tune routine uses to set the current-loop bandwidth, so any error in cable resistance on long motor leads shows up as a tuning residual rather than as a thermal fault.","metaTitle":"Schneider ILM1003P31A0000 Servo Motor, 3.5 N.m, 1100 W","metaDescription":"Schneider ILM1003P31A0000 PacDrive 3 ILM integrated servo motor, 3.5 N.m nominal torque at 3000 rpm, 1100 W, IP65, Hiperface feedback.
