The ILM1401M12F0000 is a servo motor with integrated drive in the Schneider Electric PacDrive 3 ILM family, sized as a 140 mm flange / 292 mm body unit designed for the standard international flange footprint used across packaging, material-handling and assembly machinery. A 24 mm keyed shaft with 50 mm length and a single 1.6 mm keyway is the mechanical interface; the housing carries IP54 protection and natural-convection cooling, meaning no auxiliary fan or ducting has to be provisioned in the machine frame.
Headline torque, speed and current envelope
Continuous working point is 8.3 N·m of nominal torque at 1500 rpm, drawing 3.15 A of line current and producing 1300 W of mechanical output — that is the figure the sizing calculation in the OEM's machine design should use as the steady-state basis. Peak capability reaches 27 N·m of stall torque with a maximum Irms of 14.6 A and a continuous stall current of 3.2 A, so the motor accepts roughly 4× its nominal current burst during acceleration or impact loads before the drive current limit clamps the loop. Holding-torque margin at standstill sits at 8.5 N·m continuous stall, only marginally above the 8.3 N·m nominal — for sustained near-stall operation the thermal envelope is the limiting factor, not the current ceiling.
Shaft loads, brake and feedback
The integrated holding brake delivers 18 N·m of static torque — rated as a fail-safe stop rather than a dynamic braking device, so the sizing rule is to oversize the brake to the application's worst-case overhauling load. Maximum radial shaft load is 2210 N at 1000 rpm and 1760 N at 2000 rpm, with axial load capped at 0.2 × Fr; any belt-drive or pinion-mounted application must run the radial force against the rated rpm curve, because a 20 % drop in permissible Fr is the penalty between 1000 rpm and 2000 rpm. Feedback is SinCos Hiperface absolute multiturn, so position is retained through power cycles without a homing routine on every restart — useful on machines where the zero reference is slow or awkward to acquire.
Winding constants for drive commissioning
Phase-to-phase stator resistance is 4.58 Ω at 20 °C, falling to 3.18 Ω phase-to-neutral at the 120 °C hot-spot rating; back-EMF constant is 175 V/krpm and torque constant is 2.65 N·m/A, so the drive can size its current-loop gain and the regenerative-energy clamp against deterministic electrical constants rather than a black-box motor. Phase-to-phase inductance of 50 mH at 20 °C dropping to 25 mH phase-to-neutral at 120 °C gives the current-loop bandwidth its time constant; with a 10-pole rotor the electrical cycle is five mechanical revolutions per sinusoidal period and the field-weakening ceiling sits well above the 1500 rpm nominal.
Sourcing and lifecycle for the BOM
Lifecycle status is recorded as current on the active Schneider Electric channel, so the part is still being built into new PacDrive 3 architectures rather than treated as a phase-out.
