PacDrive 3 ILM integrated servo — frame and class
The ILM1002P31F0000 is a PacDrive 3 ILM servo motor with an integrated drive, combining the servo amplifier and the rotary motor in a single 100 mm flange housing so the cabinet-side drive shelf drops out of the bill of materials. Body length is 11.02 in (280 mm) with a 1.2 in (30 mm) keyed shaft on one end and no second shaft — a standard flange mount on 9 mm clearance holes, 4-hole pattern, 95 mm centring collar, so it lands in the conventional IEC frame footprint without a custom adapter plate.
910 W mechanical envelope and torque window
Nominal output power is 910 W at a nominal torque of 2.9 N.m and 3000 rpm nominal speed — sized for mid-range dynamic axes such as packaging indexers, labelling heads, or small gantry drives where the duty sits well below the peak. Peak stall torque reaches 18.3 N.m with continuous stall torque of 4.4 N.m, meaning the axis can accelerate hard through indexing moves and still hold position under steady-state load without tripping the I²t foldback. Continuous stall current is 2.9 A and maximum RMS current 13.1 A; with a torque constant of 1.52 N.m/A the drive loop asks for a current command in the same band as the motor's thermal envelope, which simplifies the commissioning current-limit setup.
Feedback, brake, shaft interface
Feedback is a single-turn absolute SinCos Hiperface encoder — the drive reads absolute position on power-up without a homing move, which is the right pick for safety-rated axes that must know their position after every E-stop. A holding brake is fitted with 5.5 N.m holding torque, matched to the 4.4 N.m continuous stall torque so the brake holds the axis at standstill even under worst-case load; rated line current for the motor winding is 2 A. The 19 mm keyed shaft carries a maximum radial load of 990 N at 1000 rpm derating to 690 N at 3000 rpm, with axial load capped at 0.2 × Fr — the coupling choice and overhung pulley geometry must respect that envelope or bearing life collapses.
Thermal path, sealing, and panel-side fit
Cooling is natural convection — no fan, no blower, no extra enclosure cutout — and the IP65 rating means the housing tolerates hose-down and dusty cell environments without a separate shrouds, which suits washdown cells in food and packaging lines. Stator resistance is 4.12 Ω phase-to-phase at 20 °C and stator inductance 21.8 mH phase-to-phase, so the drive's current-loop bandwidth and the auto-tuned gain defaults can be calculated without a manual step-response sweep on first commissioning.
