Sizing envelope for a PacDrive 3 axis
The ILM1401M02F0000 sits in the PacDrive 3 ILM family as a servo motor with integrated drive — flange size 140 mm, nominal torque 8.3 N.m (73.5 lbf.in) at 1500 rpm, peaking at 27 N.m (239.0 lbf.in) when the drive pushes the 14.6 A Irms ceiling through the windings. Continuous output is rated at 1300 W with a 3.15 A line-rated current and a 3.2 A continuous stall current — the gap between continuous and peak (3.2 A vs 14.6 A) is the dynamic headroom the drive uses for accel/decel pulses, which is what makes this frame size work on cyclic packaging or indexing axes. Holding torque with the brake engaged is 18 N.m (159.3 lbf.in), exceeding the nominal torque figure so the brake can hold the load at zero speed without slipping — a 24 mm untapped shaft with no second shaft end and a 50 mm shaft length drives the coupling choice.
Feedback, brake, and the safety-side wiring
Feedback is absolute multiturn SinCos Hiperface — the position resolution comes from the encoder protocol rather than from an external homing routine, so the axis is position-known at power-on without a homing move. The holding brake is included and rated at 18 N.m — wire it through the drive's brake control output (not a separate supply) so the drive interlocks brake release with enable and applies the brake on stop categories that require it.
Mechanical fit and shaft loading budget
Mounting is international standard flange with a 130 mm centring collar, 3.5 mm depth, and four 11 mm mounting holes — the 140 mm flange and the bolt circle match the standard IEC mounting footprint for this frame. Maximum radial force Fr is 2210 N at 1000 rpm, derating to 1760 N at 2000 rpm — that derating curve is what governs pulley or pinion placement, not the headline torque number. Maximum axial force Fa is limited to 0.2 × Fr, so a belt drive with side load must stay inside that envelope or the bearings take the penalty.
Sourcing posture for this build
For a quote against the BOM, the unit ships as a single piece per package with natural-convection cooling — no external fan to derate around in a sealed cabinet.
