PacDrive 3 integrated drive in a 140 mm flange
The Schneider Electric ILM1401P31F0000 is an integrated servo motor and drive from the PacDrive 3 range, with the drive electronics packaged directly into the motor housing rather than mounted separately in the panel — so the cabinet layout collapses to the motor and the connecting cable, not a stand-alone amplifier chassis beside it. It bolts to the machine through an international-standard 140 mm flange, with a 130 mm centring collar and four 11 mm mounting holes; the 292 mm body length and the 24 mm keyed shaft are the two numbers that decide whether it physically drops into the existing bracket and coupling on the line.
Continuous 4.6 N.m, 1450 W, 3000 rpm envelope
Continuous torque is 4.6 N.m at 2.9 A nominal current, climbing to 7.5 N.m continuous stall at 4.7 A — meaning the motor can hold that torque indefinitely at zero speed with the rotor locked, which matters for vertical-axis or tension-control loads where the motor is parked under load for long periods. Peak torque reaches 27 N.m for the acceleration and deceleration transients, drawing up to 18.8 A Irms from the drive — so the sizing question is whether the machine's worst-case accel/decel cycle fits inside that 27 N.m envelope without tripping the drive on peak current. Nominal output power is 1450 W at 3000 rpm, with the 1.6 N.m/A torque constant at 120 °C winding temperature — the constant is the figure that converts amps commanded by the drive into torque at the shaft, and the 120 °C reference temperature means the real-world torque at a colder 25 °C winding is fractionally higher.
Hiperface feedback, integrated brake, IP65 sealing
Position feedback is an absolute single-turn SinCos Hiperface encoder, so absolute position survives a power cycle without re-homing — a practical benefit on packaging and converting lines where the machine must know its position the instant the E-stop is released, not after a return-to-reference move. The motor ships with an 18 N.m holding brake and without a second shaft end; the brake is the safety element for vertical axes and the absence of a rear shaft extension means any hand-crank or manual override has to engage through a coupling on the front keyed shaft. IP65 sealing on the body and natural-convection cooling mean the motor runs without an external fan — the housing sheds heat through its own surface area, so the cabinet or shroud around it must not blanket the fins. IP65 covers dust-tight and low-pressure water-jet washdown, which is the rating needed for food, beverage, and pharmaceutical lines where the motor sits inside the wash zone.
Stator and shaft-load numbers that govern sizing
Stator resistance drops from 1.81 Ω phase-to-phase at 20 °C to 1.26 Ω phase-to-neutral at 120 °C, and inductance falls from 19.1 mH to 9.55 mH over the same span — the high-temperature figures are what the drive's current loop actually sees in steady-state operation, and they govern the loop bandwidth the controller can close without instability. Maximum radial load is 2210 N at 1000 rpm, falling to 1530 N at 3000 rpm, with axial load capped at 0.2 × Fr — those limits protect the front bearing and the shaft, and a timing-belt or pinion drive that exceeds them at top speed is the classic cause of premature bearing failure on this class of motor.
