PacDrive 3 ILM servo motor with integrated drive electronics
The ILM1401M32A0000 is a Schneider Electric servo motor with integrated drive from the PacDrive 3 range, short-named ILM, drawing on the absolute multiturn SinCos Hiperface feedback protocol with a 128-period resolver track. The 'integrated drive' class folds the power stage into the motor housing, which removes a separate cabinet-mount amplifier and cuts the backplane footprint to a single cable run. Rated at 8.3 N.m nominal torque and 27 N.m peak stall torque, it delivers 1300 W of nominal output power at 1500 rpm — comfortably sized for high-dynamic packaging, converting, and material-handling axes where point-to-point moves repeat hundreds of times a minute. The continuous stall current sits at 3.2 A with a maximum Irms of 14.6 A, so the drive sizing works against the 14.6 A short-term ceiling for acceleration transients, not the 8.3 N.m continuous number.
8.3 N.m nominal, 27 N.m peak — sizing the torque envelope
Line rated current of 3.15 A matches the continuous-stall figure within rounding — confirming the motor is sized for sinusoidal commutation around 3 A rather than a high-overload duty. The 10-pole construction keeps the electrical frequency moderate at 1500 rpm, which sits well inside the drive's switching range and avoids the high-speed iron-loss penalty that bites larger-pole machines.
Back-EMF, winding resistance, and the inductance profile
Back-EMF constant of 175 V/krpm at 20 °C means the motor acts as a 175 V generator at 1000 rpm — at the 1500 rpm nominal point the back-EMF climbs to roughly 263 V, so the DC bus on the integrated drive must sit comfortably above that line under all load conditions or the current loop loses authority. Stator resistance climbs from 3.18 Ohm Ph/N at 120 °C to 4.58 Ohm Ph/N at 20 °C, and inductance halves between 120 °C (25 mH Ph/N) and 20 °C (50 mH Ph/Ph equivalent) — the current-loop bandwidth the drive can actually close depends on which thermal point is being serviced.
140 mm flange, keyed shaft, IP65 — mechanical integration
The 140 mm international-standard flange mounts on four 11 mm holes with a 130 mm centring collar set 3.5 mm deep, and the body itself is 254 mm long with a 40 mm key width — that footprint is what determines gearhead or planetary-coupler selection downstream of the motor face. The keyed shaft is 24 mm diameter × 50 mm long with no second shaft end, no holding brake, and natural-convection cooling — meaning the thermal envelope is set by the housing fin area, not a forced-air stream, and any mounting shroud has to leave the surface airflow path open. IP65 sealing on the housing lets the motor sit close to the process — washdown zones, food-contact conveyors, or anywhere cabinet air is not clean — as long as the shaft seal and cable gland entries are kept torqued to spec. Maximum radial load of 2210 N at 1000 rpm derates to 1760 N at 2000 rpm and the axial budget is capped at 0.2 × Fr; both numbers matter when a pinion or coupling is selected because the side load from a belt drive can exceed Fr long before the motor itself overheats.
Production status and supply posture
Lifecycle stage is recorded as current — no PCN or end-of-life notice is on file against the order code, and there is no official successor listed. For a packaging-line OEM running this motor in serial production, that reads as a clean BOM position: qualified part, no requalification triggered, no second-source gate forced by an LTB clock.
