Where this ILM1401M31A0000 sits today
As an integrated servo motor rather than a stand-alone drive, it ships as one mechanical unit: feedback, bearings, and stator in a single IP65-rated housing — so the spec table is the BOM line, no separate amplifier on the order.
Torque, speed and the rating that actually decides the fit
Continuous stall torque is 8.5 N.m and peak stall reaches 27 N.m, so the motor can deliver roughly three times nominal for acceleration pulses — enough headroom for indexing and start-stop motion without slipping into a larger frame. Nominal torque sits at 8.3 N.m at 1500 rpm, which translates to a 1300 W mechanical output point. Above that speed the constant-power region begins; the back-EMF constant of 175 V/krpm is the figure that sets how hard the upstream PacDrive controller has to push the DC bus to reach rated speed. Continuous current is 3.2 A with a peak Irms of 14.6 A — the peak-to-continuous ratio is the same 3× envelope the torque rating shows, confirming the drive can over-current for short bursts without tripping the protection.
Feedback, winding and the electrical side
Feedback is single-turn SinCos Hiperface with 128 periods per turn, which is the standard PacDrive absolute encoder profile — position is retained after power-down without a battery, and the controller hands it multi-turn info from the drive-side gearing when needed. Stator resistance is 4.58 Ohm phase-to-phase at 20 °C, dropping to 3.18 Ohm phase-to-neutral at the 120 °C hot-spot; inductance shows the same 2:1 ratio (50 mH Ph/Ph vs 25 mH Ph/N at the same temperatures). These numbers are what the drive uses to model the torque loop — they are the constants the commutation algorithm depends on, not selection parameters for the buyer. Torque constant is 2.65 N.m/A referenced at the 120 °C winding hot-spot, so a 3.2 A continuous stall produces the rated 8.5 N.m — the figures tie out internally and confirm the motor is being driven within its thermal envelope, not just its current envelope.
Flange, shaft and IP65 — mounting the old footprint
Mounting is an international-standard flange on a 140 mm motor frame with a 130 mm centring collar and four 11 mm holes — a common B5-style footprint that often drops into the same machine base as the older 140-frame servos it replaces. The keyed shaft is 24 mm diameter by 50 mm long with a 1.6 in (40 mm) keyway — a heavy-duty output suitable for belt or pinion coupling without a second shaft end protruding. Maximum radial load is 2210 N at 1000 rpm derating to 1760 N at 2000 rpm, and axial load is capped at 0.2 × Fr, so the coupling choice matters more than the bolt pattern. IP65 sealing at the housing means the body tolerates hose-down and dusty cells but is not rated for submersion — fine for the typical plant floor, not for a wet-process washdown. Cooling is natural convection, so the motor must be mounted with adequate clearance around the body and not blanketed inside a sealed enclosure.
What the absence of a holding brake means here
This build ships without a holding brake and without a second shaft end, so vertical-axis applications that need a fail-safe park position will need an external brake or a different motor variant — the ILM1401M31A0000 is sized for horizontal motion or for systems that hold position through the controller's torque.
