Product Description:

The IL03030A1C1 coil assembly belongs to the IL Ironless DDL Motors series produced by Kollmorgen. As the moving-coil portion of an ironless direct-drive linear motor, it generates linear thrust across a permanent-magnet track without contacting bearings or gear trains. This construction reduces cogging forces and supports high-precision positioning tasks common in semiconductor stages, electronic pick-and-place modules, and light mechanical actuators. Because motion is produced directly along the axis, the assembly is also well suited to applications that require smooth travel and fast response.

During continuous duty, the assembly delivers a thrust of 19 N while drawing 2.3 Arms; these paired values indicate the force available for indefinite operation without overheating. The copper windings present an electrical resistance of 3.1 Ω L-L and an inductance of 0.65 mH L-L, parameters that influence the drive’s voltage requirements and its ability to reject current ripple. Back electromotive force is characterized by 6.9 V peak / m/s L-L, so the drive controller must supply a matching voltage margin as stage velocity increases. These ratings describe the steady-state electrical load seen by the amplifier and help size cabling, supply rails, and current feedback loops.

For short intervals, the assembly can produce a peak force of 60 N at up to 7.1 Arms, enabling fast settling and short move times. With a maximum theoretical acceleration of 43.7 g, lightweight carriages can be driven rapidly if structural resonance is controlled. The coil may reach a surface temperature of 130 °C before thermal limits are exceeded, and a thermal resistance of 3.22 °C/Watt describes how quickly heat is removed by conduction and airflow. An electrical time constant of 0.21 ms combines with a force constant of 8.4 N/Arms to support crisp current-to-force conversion. Mechanical dimensions of 57.30 mm coil width and a 0.74 mm magnetic air gap set the clearance and track spacing, while a coil mass of 0.14 kg and a motor constant of 3.9 N√W affect overall stage inertia and efficiency.
