PacDrive 3 integrated servo, 1.3 kW at 1500 rpm
The ILM1401M11F0000 is a servo motor integrated drive from the PacDrive 3 family, short-named ILM, with a 140 mm flange and a 1300 W nominal output at 1500 rpm, making it the mid-frame building block in the PacDrive 3 servo range rather than the high-inertia or high-speed option. Continuous stall torque is 8.5 N.m and peak stall torque is 27 N.m, so the motor has roughly a 3× overload headroom above continuous rating — that margin is what lets it accelerate inertial loads without immediately tripping the drive into the current limit. Continuous stall current of 3.2 A and a maximum Irms of 14.6 A set the operating envelope; the 4.5× ratio between continuous and peak current is the figure the drive firmware uses to size the boost window during acceleration.
Torque, speed, and electrical constants
Nominal torque is 8.3 N.m at 1500 rpm, paired with a torque constant of 2.65 N.m/A at the 120 °C hot winding, so the i²t thermal model in the drive uses the hot-side constant rather than the cold 25 °C figure — a common mistake when sizing current loops against the motor label. Back-EMF constant is 175 V/krpm at 20 °C, meaning a freely spinning ILM1401M11F0000 at 1500 rpm regenerates about 262 V back into the DC bus — relevant when sizing the PacDrive 3 brake chopper threshold and the regeneration resistor for fast deceleration profiles. Stator resistance is 4.58 Ohm phase-to-phase at 20 °C (3.18 Ohm phase-to-neutral at 120 °C) with 50 mH phase-to-phase inductance at 20 °C and 25 mH phase-to-neutral at 120 °C, the values the drive uses to model the copper loss and the current-loop bandwidth before autotuning.
Hiperface feedback, holding brake, and shaft
Feedback is an absolute single-turn SinCos Hiperface encoder, which gives absolute position within one mechanical turn at power-on without a homing move — important on packaging and indexing machines where the axis must know its position before the first motion command. The motor ships with a holding brake (18 N.m) and a keyed single-shaft end, 24 mm diameter and 50 mm long — a standard IEC interface that drops into most gearbox and coupling selections without adapter sleeves.
Mechanical envelope and thermal envelope
The flange is the international standard 140 mm mount, 11 mm mounting holes on a 130 mm centring collar with a 3.5 mm depth — body length is 292 mm, matching the standard PacDrive 3 ILM140 footprint for cabinet layout planning. Cooling is natural convection, so the IP54 rating holds only as long as the motor surface is not enclosed in a sealed thermal blanket — derating applies in any panel build where the surrounding air temperature exceeds the standard 40 °C ambient. Maximum radial force is 2210 N at 1000 rpm derating to 1760 N at 2000 rpm, with maximum axial force capped at 0.2 × Fr — these numbers govern the permissible belt tension or pinion gear mesh load before bearing life shortens.
