Product details

An all-in-one motor/drive with a 140 mm flange footprint

The Schneider Electric ILM1401M21F0000 is a PacDrive 3 series ILM servo motor with an integrated drive stage, built around an international standard flange with a 5.5 in (140 mm) motor flange size and a body length of 11.5 in (292 mm), so it drops into a standard NEMA-style machine mount without adapter plates. Natural convection cooling is the only thermal path on the unit, which keeps the cabinet clean of fans and ducting — but it also means the continuous torque rating assumes the mounting surface acts as a heatsink, and a stuffed enclosure will pull continuous torque down long before it trips the peak figure.

Torque, speed, and what the 1300 W envelope actually means on the line

Continuous stall torque lands at 8.5 N·m with a continuous stall current of 3.2 A and a line-rated current of 3.15 A, while peak stall torque reaches 27 N·m and the drive can deliver a maximum Irms of 14.6 A — that's roughly a 3× overload headroom for short accel/decel bursts on a conveyor index or a small press feed. Nominal torque is 8.3 N·m at the rated 1500 rpm, which lines up with the 1300 W nominal output power — pick a gearbox or pulley ratio off the 8.3 N·m figure for steady-state sizing, and reserve the 27 N·m peak only for short move profiles where duty cycle stays below the thermal ceiling.

Feedback, brake, and shaft detail for the panel-builder

Position feedback is an absolute single-turn SinCos Hiperface encoder, so the controller reads absolute shaft position on power-up with no homing routine — appropriate for indexed motion where losing position after an E-stop would cost a re-home cycle. A holding brake is fitted and rated 18 N·m holding torque, paired with a 24 mm untapped shaft and a 2.0 in (50 mm) shaft length with one keyway at 1.6 in (40 mm) width — there is no second shaft end, so any auxiliary encoder or hand-crank decoupler needs its own bracket. Maximum radial load is 2210 N at 1000 rpm, dropping to 1760 N at 2000 rpm, and maximum axial force is capped at 0.2 × Fr — a belt drive with too much pre-tension will eat the bearings long before the drive ever faults.

Sealing, electrical constants, and what IP65 actually buys you

IP65 sealing on the motor body suits washdown-adjacent areas and most outdoor enclosures, but it is not IP67 — high-pressure hot-water cleaning directly on the unit will eventually defeat the seal. Stator resistance reads 4.58 Ohm phase-to-phase at 20 °C and 3.18 Ohm phase-to-neutral at 120 °C, with stator inductance of 50 mH Ph/Ph at 20 °C and 25 mH Ph/N at 120 °C — these are the values to feed into a torque-loop or field-weakening model, and the temperature coefficient is significant enough that a cold-start tune will drift once the motor warms up.

Frequently asked questions

What is the listed length of the ILM1401M21F0000 on this servo drive line?

The ILM1401M21F0000 ships at 11.5 in (292 mm) end-to-end with a 140 mm flange and a 24 mm shaft, so verify the available cabinet depth and the shaft-to-coupling clearance before pulling the motor out of stock.

What is the closest pin-compatible alternative to the ILM1401M21F0000 in this servo drive family?

The PacDrive 3 ILM family covers multiple lengths and brake/feedback combinations on the same 140 mm flange — the next size up or down will share the mounting pattern, but exact torque and inertia ratings differ. Confirm the substitute code against the OEM configurator before swapping on a running line.
