Product Description:

The IL24100A3TRC4 is an ironless direct-drive linear motor coil produced by Kollmorgen for the IL Ironless DDL Motors series. This moving coil works against a stationary permanent-magnet track to generate linear thrust without cogging, making it useful for semiconductor handlers, precision pick-and-place stages, and other automation axes that demand smooth, fast motion with minimal hysteresis. This design removes ferromagnetic material from the translator, so attractive forces to the magnet rail are low, easing bearing loads and enabling submicron positioning under servo control. The moving coil contains the active windings while the magnet track remains fixed to the machine structure, which helps keep the moving assembly light during rapid direction changes.

Under continuous duty, the coil delivers a steady thrust of 262 N while drawing 4.6 Arms per phase. The force constant is 57 N-m/Arms, and the back-EMF constant is 46.6 Vpk/m/s, allowing the drive to predict voltage requirements from commanded velocity. The active section is 398.8 mm long, and the coil fits compact stages with limited moving mass. Copper windings present 3.7 ohms of resistance at 25 °C and an inductance of 1.75 mH, which affect current loop response and regeneration behavior. Overall coil height is 148.5 mm, and thermal energy exits through the aluminum body with a 0.22 °C/W path, supporting the rated continuous output without auxiliary liquid cooling.

For short bursts, the winding current may rise to 28.1 Arms, increasing instantaneous force to 1600 N. Mechanical output reaches 1538 W when the duty cycle and cooling permit. The mating magnet track contributes 27.3 kg of mass per meter, so the machine base must support that load while maintaining a uniform air gap along the axis. Consistent alignment across the travel path helps prevent side loading on the translator and preserves smooth linear motion during high-acceleration moves.
