The ILM0701P31F0000: It is a member of the PacDrive 3 range and carries the ILM device short name, which is Schneider's integrated-drive servo family: the drive electronics are bundled into the motor housing itself rather than sitting in a separate cabinet amplifier, so the field-replacement unit is one assembly rather than a motor/drive pair.
Torque and speed envelope for sizing the axis
Continuous stall torque is 1.1 N·m and nominal torque is 0.5 N·m at the 6000 rpm ceiling, with peak stall reaching 3.5 N·m for acceleration transients — a small-frame servo sized for light packaging, indexing tables, or auxiliary axes where the motion is short-stroke but dynamic. Peak torque capability is supported by a maximum current Irms of 5.7 A against a continuous stall current of 1.55 A, so the axis can be commanded at roughly 3.7× its continuous rating for short bursts before thermal limits kick in — a ratio to budget into any fast-accel/decel profile. The integrated holding brake delivers 3 N·m of static holding torque, which is above the motor's continuous torque rating; the brake holds the axis at standstill with the drive unpowered rather than serving as a dynamic stopping element.
Feedback, windings, and the drive-side signature
Position feedback is an absolute single-turn SinCos Hiperface encoder, so the drive knows absolute shaft angle on power-up without a homing move — useful on machines where the reference position must survive a power cycle without re-seek. The torque constant of 0.71 N·m/A at 120 °C winding temperature sets the current-to-torque gain the drive has to model for thermal compensation; back-EMF constant of 46 V/krpm at 20 °C limits the safe no-load top speed at any given DC-bus voltage the PacDrive amplifier supplies.
Mechanical fit — flange, shaft, and shaft loads
The motor uses an international-standard 70 mm flange with a 60 mm centring collar and four 5.5 mm mounting holes; the keyed shaft is 11 mm in diameter by 23 mm long with an 18 mm key — a compact footprint that drops into standard NEMA/IEC 70 mm servo mounting patterns. Shaft load ratings are 660 N radial at 1000 rpm, derating down to 360 N at 6000 rpm, and axial force capped at 0.2× the applied radial value — these are the mechanical limits that drive the choice of coupling, the permissible overhung load from a gearbox or pinion, and the thrust budget for any screw or belt preload. There is no second shaft end, so a manual override handwheel or auxiliary encoder cannot be mounted on the rear — any service access has to be planned at the front shaft or by decoupling the driven element.
Environment and thermal path
IP65 sealing on the motor housing means the unit tolerates dust and low-pressure water jets — a washdown-adjacent duty where the cabling gland is the sealing point rather than the housing face, and the motor can be panel-mounted near coolant splash zones that a standard IP54 servo would not survive. Cooling is by natural convection only — there is no integrated fan, so the axis must be mounted with clearance around the body and derated if it is enclosed in a sealed cabinet without forced airflow, since the integrated drive electronics add to the heat the fins have to shed.
