Product Description:

The IL06030A1TRP1 linear motor coil is manufactured by Kollmorgen as part of the IL Ironless DDL Motors series. This ironless direct-drive forcer works with a separate magnet track to generate smooth, cog-free linear thrust. By eliminating ferromagnetic attraction, the coil has low moving mass, which supports high acceleration and micron-level positioning. The moving coil carries only the active winding assembly, so the stationary magnet track supports the heavier magnetic structure off the axis carriage.

During continuous duty, the coil develops 30 N of thrust while drawing 1.8 Arms, establishing its thermal operating point at 25 °C. The coil has a DC resistance of 6.1 Ω and an inductance of 1.3 mH, which support current-loop tuning in the drive. The current-to-force relationship is expressed by the 16.8 N/Arms force constant, so a one-amp change produces nearly 17 N of additional force. A 110.8 mm coil length and 0.27 kg translator mass help minimize inertia, and the active section spans 78.5 mm over the magnet way to maintain air-gap uniformity. Heat created in the windings is conducted through the housing toward the machine frame, and the thermal path is rated at 1.61 °C/W for continuous operation without auxiliary cooling.

Transient moves are supported with a ceiling of 120 N when the amplifier supplies 7.1 Arms of peak current, giving a four-to-one multiplier over the continuous rating for rapid acceleration and settling. The motor constant is 5.6 N/√W, and the output capability is 303 W within a compact envelope. The back electromotive force constant is 13.7 Vpk per meter per second, which is important when sizing bus voltage and regenerative clamps during high-speed strokes. The magnet way adds 9.4 kg per meter to the stationary mass, increasing rigidity while keeping the moving element light. This operating balance supports smooth motion on long-stroke positioning axes.
