70 mm flange, 720 W integrated-drive servo motor
The Schneider Electric ILM0703P32F0000 is a PacDrive 3 ILM series servo motor with integrated drive, built on a 70 mm flange with three motor stacks and a length of 11.5 in (293 mm), which sets the frame size for cabinet layout and cable routing at the machine. The unit is specified for 720 W nominal output at 1.5 A line current, with a continuous stall torque of 19.5 lbf.in (2.2 N.m), a nominal torque of 10.18 lbf.in (1.15 N.m) and a peak stall torque of 77.001 lbf.in (8.7 N.m), so the working point sits well below peak — the 8.7 N.m ceiling is the short-duration acceleration reserve, not the steady-state rating. A keyed shaft of 0.6 in (14 mm) diameter and 1.2 in (30 mm) length is fitted with a holding brake rated 26.6 lbf.in (3 N.m) and supplied without a second shaft end — the brake holds the load at rest and the single shaft end means the coupling choice and any belt or pinion stage must respect the 14 mm keyed interface.
Speed, electrical constants, and feedback
Nominal speed is 6000 rpm and the maximum current is 12 A Irms, giving a torque constant of 0.76 N.m/A at 248 °F (120 °C) — that figure is the hot winding value, so the actual torque per amp at a cold 68 °F (20 °C) start is higher and the drive's current loop must be sized against the 12 A ceiling, not the 1.5 A nominal line current. Back EMF is 49 V/krpm at 68 °F (20 °C), which is the regen voltage that lands on the DC bus at top speed — overspeed a stalled decel and the drive's brake chopper has to absorb that envelope to avoid DC-bus overvoltage trips. Stator resistance is 2.7 Ohm Ph/Ph at 68 °F (20 °C) and 1.88 Ohm Ph/N at 248 °F (120 °C), with stator inductance of 13 mH Ph/Ph at 68 °F (20 °C) and 6.5 mH Ph/N at 248 °F (120 °C) — the resistance drop with temperature and the inductance halving with temperature set the current-loop bandwidth the drive must close across the operating window. Position feedback is absolute multiturn SinCos Hiperface, which carries absolute position over a single cable without a battery-backed encoder — for PacDrive 3 motion control that means the axis stays referenced after a power cycle and the commutation angle is resolved on the first sine/cosine period, not on a homing move.
Mechanical envelope and mounting
The motor mounts on an international standard flange with four 0.2 in (5.5 mm) mounting holes, a centring collar of 2.4 in (60 mm) diameter and 0.10 in (2.5 mm) depth — the centring collar takes the shear so the mounting bolts hold the axial load, not the bearing assembly. Maximum radial force Fr derates from 730 N at 1000 rpm to 400 N at 6000 rpm, and maximum axial force Fa is capped at 0.2 x Fr — these are belt and pinion loads the bearing can carry, not external process forces, and any overhung load calculation must use the Fr curve at the actual operating speed. Cooling is natural convection with IP65 sealing on the body and shaft seal, so the motor mounts in a cabinet or on a machine frame without a fan but cannot sit in a washdown or submerged enclosure — IP65 tolerates splashed water and dust, not hosed cleaning.
