Product Description:

The ICD1003A1P102 is a linear motor coil produced by Kollmorgen as part of the ICD Ironcore Direct Drives series. Designed for mounting on a magnet track, the coil converts drive current into linear thrust for precision positioning systems in pick-and-place modules, gantries, and semiconductor stages. The coil body width is 55.0 mm, allowing integration into compact mechanical frames, and the moving mass is limited to 1.1 kg to preserve dynamic response. This combination of compact width and low moving mass supports fast direction changes on axes where payload and carriage space are limited. Three pre-tapped mounting holes simplify attachment to the forcer plate while maintaining repeatable alignment along the axis of motion.

During continuous operation, the forcer is rated for a drive current of 1.9 Arms, which, in combination with its force constant of 53.5 N/Arms, delivers a sustained thrust of 104 N. Internally, the copper windings present a line-to-line resistance of 6.4 Ohms, which influences ohmic losses at nominal current and affects drive voltage requirements. The inductance between phases is 18.3 mH, which affects current rise and the electrical response of the servo system. A back-EMF constant of 43.7 Vpk/m/s indicates the voltage generated as speed increases. The motor constant of 17.3 N/√W relates thrust production to dissipated power. Heat generated in the coil flows through a thermal resistance of 2.05 °C/W to the mounting surface.

For transient moves, the coil withstands a peak drive of 7.9 Arms, producing up to 330 N of short-duration thrust before thermal limits are approached. The electrical dynamics remain responsive, as the current rises to its commanded value within an electrical time constant of 2.9 ms. The system is also subject to a static magnetic attraction of 1.06 kN between the coil and the iron core, and the maximum winding temperature of 130 °C must not be exceeded. A rigid mounting surface is important because both heat transfer and attraction force act through the installed coil assembly. The three mounting holes secure the forcer firmly, maintaining a stable thermal path and helping restrain the attraction load.
