Product Description:

The IL18030A1TRC4 is an ironless direct-drive linear motor coil produced by Kollmorgen within the IL Ironless DDL Motors series. Designed for industrial automation, the coil interacts with a permanent-magnet track to create controlled linear thrust without mechanical transmissions, making it suitable for positioning stages and gantry axes. In this configuration, Kollmorgen supplies the moving coil element while the user mounts it over a stationary magnet track. The IL18030A1TRC4 therefore offers low cogging force and high dynamic response for precision motion tasks.

During continuous operation at 25 °C, the coil delivers 92 N of thrust while drawing 1.8 Arms. This rating is supported by a direct current resistance of 18.2 ohms, which limits resistive losses during sustained motion. The generated back electromotive force scales at 41.2 Vpk/m/s, showing the voltage the drive must supply as the slider accelerates. For each ampere of phase current, the coil produces 50.5 N/Arms, giving the controller a predictable relationship between commanded current and linear thrust. When short bursts are required, the drive may supply 7.1 Arms, allowing higher peak thrust without exceeding thermal limits.

The assembly weighs 0.57 kg, spans 302.8 mm in active length, and sits 78.5 mm above the magnet rail, leaving room for cable management in compact machines. The accompanying magnet track contributes 9.4 kg per meter of length, providing the reaction mass needed for peak events up to 360 N of instantaneous force. Under rated conditions, the coil converts electrical energy to motion at 626 W, and its line-to-line inductance of 3.8 mH works with the servo amplifier to filter switching ripple. A motor constant of 9.7 N/√W quantifies conversion efficiency, while a thermal resistance of 0.536 °C/W shows the temperature rise per watt that must be removed through the mounting surface.
