Flange footprint and what mounts against it
The ILM1401P01F0000 sits on a 140 mm international-standard flange with a 130 mm centring collar sitting 3.5 mm proud of the face, and four 11 mm mounting holes arranged on the bolt circle — drop-in to the standard machine-mount cutout without adapter plates. Body length is 11.5 in (292 mm) with a 1.6 in (40 mm) key width on the shaft, so the coupling and gearbox sizing done for any other ILM-frame unit carries straight across to this variant.
Torque, speed, and the current that drives them
Nominal torque is 4.6 N.m continuous at 3000 rpm with a 1450 W output, and the motor can swing up to 27 N.m peak stall for acceleration ramps — that envelope is what defines the sizing band, not the headline 4.6 N.m figure on its own. Line current is 2.9 A nominal with a 4.7 A continuous stall current, and the drive tolerates 18.8 A Irms transient — useful when sizing the PacDrive amplifier channel and the upstream branch protection together. Holding torque from the integral brake is 18 N.m, enough to lock the shaft against the back-driving loads seen on vertical axes at standstill without an external holding device.
Shaft, feedback, and rotor mechanics
Shaft is 24 mm diameter, 50 mm long, untapped, with no second shaft end — the single output side keeps the seal path simple on this frame. Feedback is an absolute single-turn SinCos Hiperface encoder on a 10-pole rotor, so position is retained through power cycles and the drive electronics read absolute angle on first connection without a homing move.
Shaft loading and the limits the coupling must respect
Maximum radial force Fr is 2210 N at 1000 rpm, dropping to 1760 N at 2000 rpm and 1530 N at 3000 rpm — the rated force is inversely tied to speed because belt and pinion loads amplify with rpm. Maximum axial force Fa is constrained to 0.2 times Fr, so a coupling or gearbox that pushes the shaft axially must be sized within that fraction rather than treated as free.
Cooling, ingress, and where it physically fits
Cooling is natural convection with no integrated fan — the motor relies on the cabinet's air movement and the flange's thermal path to the machine structure, which keeps acoustic noise low but means derating applies in sealed enclosures. IP54 ingress protection on the body handles dust and light splash typical of general industrial cabinets; this is not a washdown-rated drive, so food-and-beverage lines or outdoor mounting need a higher-rated alternative. Back EMF constant is 108 V/krpm at 20 °C and the stator resistance is 1.81 Ohm phase-to-phase at 20 °C — the constants drive the amplifier sizing math for regen and braking resistor selection.
