Where does the ILM1003P21F0000 land on a PacDrive 3 axis?
The ILM1003P21F0000 is a Schneider Electric PacDrive 3 ILM servo motor with an integrated drive — a single-cable axis that pairs the power stage directly with the rotor rather than running a separate drive cabinet per axis. Stator feeding a 3.5 N.m continuous torque at 3,000 rpm nominal with a 28.3 N.m peak torque ceiling means the axis has roughly 8× overload headroom for acceleration transients and indexing moves before the drive current-limits. A 5.8 N.m continuous stall torque at 3.6 A continuous stall current sets the thermal-floor derating point — the curve above which cooling, not torque capacity, governs the duty cycle. With natural convection as the only cooling path, panel thermal planning matters; the ILM1003P21F0000 cannot be derated upward by adding a fan, only down by trimming the motion profile to keep I²R heating below the housing thermal rise.
Shaft, flange, and the cabinet cut-out
An international-standard 100 mm flange with four 9 mm mounting holes on the standard bolt circle and a 95 mm centering collar drives the panel cut-out. The 19 mm untapped shaft with a 40 mm length and 30 mm keyway is sized for direct coupling to a gearbox or pinion without an intermediate sleeve. A second shaft end is omitted, so a manual handwheel or absolute multi-turn backup cannot be added later without re-specifying the motor. Radial shaft load is rated 1,050 N at 1,000 rpm and drops to 730 N at 3,000 rpm — the right part of the derating curve a belt or pinion drive sits on, which is why the motor stack count and inertia matter when sizing the coupling. Axial load is bounded at 0.2 × Fr, a conservative figure that treats the bearing as radial-limited. IP65 sealing on the body keeps coolant, oil mist, and cutting chips out of the rotor cavity, so the ILM1003P21F0000 can sit close to the process — typical PacDrive deployments push these onto machine frames rather than into a control cabinet.
Feedback, brake, and electrical constants
Absolute single-turn SinCos Hiperface feedback resolves position within one mechanical revolution and reports it back to the PacDrive controller through the Hiperface protocol — the loop bandwidth ceiling is set by this interface and the controller's sample time, not the motor itself. The integrated 9 N.m holding brake is a fail-safe parking brake sized to hold the rotor with the rated load; it is not a dynamic stopping brake for emergency stops. Back-EMF constant of 103 V/krpm at 20 °C and a torque constant of 1.61 N.m/A at 120 °C wound temperature gives the commissioning engineer the open-loop figures for sizing the DC-bus ramp and the current loop gains. Stator winding resistance measures 2.6 Ohm phase-to-phase at 20 °C and drops to 1.81 Ohm phase-to-neutral once warm — the inductance figure splits the same way across temperature, so the drive's auto-tune should be run at the expected operating temperature, not cold.
Lifecycle and how to source it
Lifecycle stage is recorded as current. The part is specified against the PacDrive 3 controller family, not the legacy PacDrive 2 or third-party servo buses, so any cross-reference must keep the same controller side intact to avoid a commissioning rework.
