Form-factor reality for a PacDrive 3 ILM
Schneider Electric ILM0703P21F0000 is an integrated servo motor — drive electronics co-packaged with the motor — in the PacDrive 3 ILM family, built around a 70 mm flange and an overall body length of 11.5 in (293 mm). The shaft is a 14 mm-diameter, untapped single-end with a 30 mm length and a 60 mm centring collar; the flange uses four 5.5 mm mounting holes, so it drops into a standard machine-builder foot pattern without adaptor plates. Cooling is natural convection with an IP65 rating on the body — splash- and dust-resistant for an enclosure-free cabinet wall or a washdown-adjacent machine frame, but not a fully sealed submergence duty.
720 W of torque in 1.15 N.m continuous slices
The ILM0703P21F0000 is rated 720 W nominal output with a continuous torque of 1.15 N.m at 1.5 A line current, climbing to a peak stall torque of 8.7 N.m at a maximum Irms of 12 A — meaning the same frame that runs a steady conveyor or indexing table can also deliver short bursts for acceleration ramps and punch-press cycles. With a torque constant of 0.76 N.m/A (at 120 °C) and a back-EMF constant of 49 V/krpm (at 20 °C), sizing the upstream PacDrive controller comes down to matching the bus voltage headroom against the 6000 rpm nominal ceiling — every 1000 rpm of speed adds roughly 49 V of generated EMF that the drive has to overcome at constant speed. Stator resistance is 2.7 Ohm Ph/Ph at 20 °C (1.88 Ohm Ph/N at 120 °C) and inductance is 13 mH Ph/Ph at 20 °C; the continuous stall current is 3 A against a 19.5 lbf.in (2.2 N.m) continuous stall torque, so the I²R thermal envelope is what limits long-duration holds at zero speed — a stalled axis needs the duty cycle watched, not just the current.
Feedback, brake, and what the shaft actually carries
Position feedback is an absolute single-turn SinCos Hiperface device, which means the controller reads absolute position within one mechanical revolution on power-up — no homing move required after every restart — at a resolution that supports the PacDrive 3 motion loop without an external encoder. Shaft loading is governed by a derating curve: radial force Fr is rated 730 N at 1000 rpm and drops to 400 N at 6000 rpm, while the maximum axial force Fa is limited to 0.2 x Fr — direct-coupled gearboxes and belt drives need their overhung load checked against the curve at the operating speed, not the headline rpm.
Sourcing posture for an integrated servo on a machine build
The ILM0703P21F0000 sits in the PacDrive 3 integrated-motor line and is specified for current production on the datasheet family record — the spec sheet carries a current lifecycle marker but no last-time-buy date or phase-out successor is published, so the buyer's risk is on availability through the authorised channel rather than on a forced redesign. Integrated servo motors of this class are typically built to order against a PacDrive controller pairing, so the practical path for a small-shop owner or an integrator is to quote the BOM line — motor plus mating PacDrive controller plus cabling — as one RFQ rather than treat the motor as a generic MRO spare.
