What the ILM1401M01F0000 is on the rack
Schneider Electric PacDrive 3 ILM1401M01F0000 is a servo motor with integrated drive, sized around a 140 mm flange with a 24 mm untapped shaft and a 50 mm stick-out, and the Hiperface SinCos single-turn absolute feedback rides right on the back of the motor so the PacDrive controller sees absolute position the moment power comes up — no homing routine on every restart. Headline torque figures land where you'd expect on this frame: 8.3 N.m nominal, 8.5 N.m continuous stall, and 27 N.m peak stall, with the integrated holding brake rated 18 N.m to hold the load with the drive disabled. Nominal speed is 1500 rpm with 1300 W of continuous output power, so the working point sits well below the mechanical ceiling and the drive has headroom for short acceleration bursts before the peak-stall number becomes the limit.
Sizing the drive loop around the motor constants
The torque constant of 2.65 N.m/A at the 120 °C winding temperature is the number that ties current command to shaft torque — 3.15 A line-rated current and 3.2 A continuous stall current sit comfortably under the 14.6 A Irms peak the integrated drive can push for short transients, so cyclic accelerations land inside the thermal envelope without tripping the I²t limit. Back-EMF constant of 175 V/krpm at 20 °C is the speed-voltage ratio that determines how high the drive can spin this motor before bus voltage headroom disappears — running at 1500 rpm nominal the back-EMF sits near 263 V on the line, which is why this frame pairs with the PacDrive 3 bus rather than a 230 V-class drive. Stator resistance and inductance both shift with winding temperature: 4.58 Ω Ph/Ph at 20 °C drops to 3.18 Ω Ph/N at 120 °C, and 50 mH at 20 °C halves to 25 mH at 120 °C — those figures feed the current-loop tuning and explain why a cold-start tune and a hot-running tune give slightly different loop gains on this frame.
Mechanical fit and the loads the bearings will see
Flange-mount footprint is the international standard layout: 140 mm motor flange, 130 mm centring collar, 11 mm mounting holes on a four-hole pattern, with a 40 mm key and 50 mm shaft length — a drop-in for any machine built around the PacDrive 3 ILM family. Shaft is 24 mm diameter, untapped, with no second shaft end, so a coupling or pinion locks onto the keyed stub with a single axial fastener — no tapped hole for a shaft-side puller means the maintenance crew needs an external puller when the coupling sticks. Radial load on the shaft end is rated 2210 N at 1000 rpm, falling to 1760 N at 2000 rpm, and axial load is capped at 0.2× the radial figure — a belt or pinion drive must be sized against the radial curve at the actual operating rpm, not against the static number on the nameplate.
Cooling, sealing, and where this motor belongs
Cooling is natural convection only — no integrated fan, no liquid jacket — so the 1300 W continuous output rating assumes the motor sits in free air with its body unobstructed; an enclosure that blankets the housing derates the continuous figure and pulls the working point down toward the nominal torque. IP54 sealing covers dust and splashing water but not washdown, so the ILM1401M01F0000 fits standard machine-room and cabinet-integrated builds — it does not belong in a food-and-bev line or any application that sees high-pressure cleaning.
