Product Description:

The IC11030A5TSP1 is an iron-core coil from Kollmorgen's IC Ironcore Direct Drive Motors series. Mounted over a permanent-magnet track, the coil produces linear thrust directly along the axis of motion, removing the need for lead screws or rack drives in automated pick-and-place heads, wafer steppers, and precision gantries. By linking motor force to servo current without intermediate transmission elements, the unit supports tight position control and rapid dynamic response in industrial automation cells. This arrangement also helps reduce backlash and other mechanical effects that can limit repeatability in high-speed positioning systems.

The coil delivers a continuous thrust of 140 N when the winding temperature is held at 25 °C, and it sustains this output while drawing 6.87 Arms. Electrical losses are influenced by a line-to-line resistance of 0.66 Ω, while current response is shaped by a phase inductance of 5.9 mH. A force constant of 20.7 N/Arms makes current loop tuning more direct because commanded current translates linearly into net thrust. Supporting data include a motor constant of 20.9 N/√W, a rated thermal load of 1,517 W, and a thermal resistance of 1.64 °C/W, and these values are used for drive sizing and heat sink design. The coil mass is 2.5 kg, which affects carriage acceleration, moving inertia, and the natural frequency of the axis.

Short-duration moves can be executed at a peak thrust of 369 N provided the drive can momentarily supply 24 Arms. When the coil sits over the magnet array, it also experiences a normal attractive preload of 1.44 kN, so the stage bearing system must carry that force during operation. During motion, back electromotive force is proportional to velocity and is quantified here at 16.9 Vpk/m/s. This relationship supports sensorless commutation at steady speed and can also assist feedback scaling in closed-loop servo control.
