Sizing the mechanical load against this PacDrive 3 motor
The ILM1003P31F0000 is a servo motor with integrated drive from the PacDrive 3 family, short-coded ILM on the model label, so sizing decisions are made on the motor envelope rather than a separate amplifier chassis. Continuous nominal torque of 3.5 N.m and a peak stall capability of 28.3 N.m mean the same frame can ride through a normal indexing cycle and a transient stall event without oversizing the drive. Continuous stall torque of 5.8 N.m against 3.5 N.m nominal tells the integrator where the thermal envelope actually sits: a duty profile that parks the shaft near standstill is the case that stresses the windings, and the natural-convection cooling on this frame has no fan to lean on when the shaft stops.
Current loop and the duty margin on the ILM frame
Line-rated current sits at 2.4 A while peak Irms is 21.2 A and continuous stall current is 3.6 A — so the headline power of 1100 W is the nominal point on the speed-torque curve, and any short-duty overload has to be budgeted inside the Irms ceiling the drive will enforce, not the nominal number on the nameplate. Back EMF at 103 V/krpm is the value that sets when the drive's DC bus runs out of headroom at high speed, and stator resistance of 2.6 Ohm at 20 °C is what determines the I²R loss budget that feeds back into the natural-convection thermal envelope.
Mounting, sealing, and the cabling side of the frame
The 100 mm flange, 95 mm centring collar, and four 9 mm mounting holes land on a standard international flange pattern, which is the case where the panel builder is reusing an existing machine base rather than machining a new adapter plate. IP65 sealing on the body means the motor sits in washdown-adjacent zones without a separate shroud, and the Hiperface absolute single-turn encoder plus the integrated holding brake close the loop on positioning axes where a vertical load has to hold position on loss of power. Shaft geometry is keyed at 19 mm diameter with a 40 mm length and 30 mm key width, and radial load limits step from 1050 N at 1000 rpm down to 730 N at 3000 rpm — a belt-driven coupling at the high end of the speed range has to be re-checked against the derating curve, not the headline figure.
