Integrated servo axis in the PacDrive 3 line
The ILM1401M22A0000: Servo motor with integrated drive in the PacDrive 3 range, device short name ILM, built around a 5.5 in (140 mm) international-standard flange and a 10-pole rotor in a single motor stack. Size for the axis: 1300 W nominal output at 1500 rpm, 8.3 N·m nominal torque and 8.5 N·m continuous stall torque, peaking at 27 N·m when the drive delivers its 14.6 A rms maximum current — the envelope the PacDrive controller will command in the S-curve profile. Feedback is absolute multiturn SinCos Hiperface at 128 periods of speed feedback resolution, so absolute position survives a power cycle without a homing move on restart — the reason it drops onto a PacDrive 3 machine as a single-cable absolute axis.
Mechanical fit on the machine bed
Body length is 10 in (254 mm) with a 1.6 in (40 mm) key width on the shaft and a 24 mm shaft diameter; the 50 mm shaft length is untapped and there is no second shaft end, so any auxiliary encoder or handwheel has to couple through the primary shaft or a belt stage. International-standard flange with a 130 mm centring collar at 3.5 mm depth and four 11 mm mounting holes — drop-in to a standard 140-frame mounting footprint common across the ILM family. Shaft load limits: maximum radial force Fr is 2210 N at 1000 rpm dropping to 1760 N at 2000 rpm, with maximum axial force Fa capped at 0.2 × Fr — direct-coupling applications stay comfortably inside the envelope, but a belt or pinion drive needs the radial force derated against these numbers before the bearing life is signed off.
Electrical and thermal envelope for commissioning
Line-rated current 3.15 A at continuous stall (3.2 A continuous stall current) and 14.6 A rms peak — the drive sizing must hold the rms demand below 3.15 A through the duty cycle, with the 14.6 A ceiling reserved for acceleration transients only. Back-EMF constant 175 V/krpm at 68 °F (20 °C) and torque constant 2.65 N·m/A at 248 °F (120 °C) — the two numbers the commissioning engineer loads into the PacDrive controller to scale current command to mechanical torque, and the hot-side value is the one to use because the motor reaches thermal steady state well above ambient. Stator winding 4.58 Ohm phase-to-phase at 68 °F (20 °C), falling to 3.18 Ohm at 248 °F (120 °C), with 50 mH phase-to-phase inductance at 20 °C — copper resistance drops ~30 % from cold to hot, so the cold-loop resistance check overestimates winding losses. Natural-convection cooling with IP65 sealing — the motor is built for cabinet-adjacent and field-mount duty where forced airflow over the housing is not available, and the IP65 rating means the cable entry and shaft seal hold up to water-jet washdown, not full submergence.
Production status and the BOM line
Package quantity is one unit per pack — on a packaging-machinery BOM this part consumes one per axis, so a four-axis machine is a four-unit line item; qualified-part status and per-unit landed cost both flow through a single BOM row. Independent distribution quoted to order against the BOM: lead time, MOQ, and volume pricing confirmed at RFQ, with full manufacturer traceability on each shipment — the right posture for an active, qualified servo frame rather than a stock-shelf claim.
