ILM servo motor integrated drive in the PacDrive 3 line
The ILM1402P22A0000 is a Schneider Electric servo motor integrated drive from the PacDrive 3 range, device short name ILM. It packages the drive electronics onto the motor frame, so the controller slice in the cabinet is replaced by a single motor-and-drive module on the machine — the loop is closed back to the PacDrive controller over the fieldbus rather than a dedicated analogue torque/velocity cable. It is a 140 mm flange size motor with international standard flange mounting and natural convection cooling, which means the integrated drive electronics rely on the motor housing as the heatsink — no external fan, so the cabinet face must still allow air movement around the body.
Torque envelope — nominal, peak, and continuous stall
Nominal torque is 9.1 N.m at 2000 rpm, drawing 3.7 A line current and delivering 1910 W of nominal output power. The 4.8 A continuous stall current and 12.5 N.m continuous stall torque are the thermal ceiling at zero speed — the rating that decides whether the machine can hold a stationary load indefinitely without tripping on I²t. Peak stall torque is 55 N.m with a maximum Irms of 24 A — the headroom used for acceleration ramps and short shock loads. In sizing terms, the 6:1 ratio between peak stall and nominal is what lets a packaging indexing axis accelerate a heavy puck without oversizing the continuous-rated motor; if the cycle demands peak torque more than a few seconds at a time, the continuous figure starts to govern instead.
Feedback, poles, and winding constants
Position feedback is absolute multiturn SinCos Hiperface with 128 periods of resolution per revolution, on a 10-pole rotor. Absolute multiturn means the absolute position survives a power cycle — no homing routine on every restart — and Hiperface SinCos carries the analogue incremental channels that the drive uses for fine interpolation between absolute singleturn frames. Back-EMF constant is 173 V/krpm at 20 °C and torque constant 2.6 N.m/A at 120 °C — the drop between the 20 °C cold figure and the 120 °C working figure is the normal magnet-flux temperature loss that the drive compensates with the motor model. Stator winding resistance is 1.9 Ω phase-to-phase at 20 °C and 1.32 Ω phase-to-neutral at 120 °C; the phase-to-phase inductance is 22 mH at 20 °C and 11 mH at 120 °C, which sets the current-loop bandwidth the drive can achieve.
Mechanical envelope and shaft loading
The motor body is 309 mm long with a 40 mm key width, and the untaped shaft is 24 mm diameter by 50 mm long — sized for a standard coupling or pulley in a packaging or indexing application. Four 11 mm mounting holes on a 140 mm international-standard flange with a 130 mm centring collar at 3.5 mm depth match the standard servo mounting footprint. The motor is supplied without a holding brake and without a second shaft end, which simplifies the mechanical stack but means the axis must rely on the drive's regenerative stop or an external mechanical brake if the application holds a vertical load at rest. The IP65 rating seals against hose-directed water and dust, suitable for food-and-beverage washdown zones and general factory environments but not for submerged duty.
