Product Description:

The IL12050A1TRP1 is an ironless direct-drive linear motor coil in the IL Ironless DDL Motors series from Kollmorgen. As a moving-coil element, it works with a permanent-magnet track to deliver cog-free thrust for positioning stages, gantries, and pick-and-place axes in industrial automation. The coil is the moving member, so the magnet track remains fixed to the machine frame during operation. With no laminated iron, detent forces are negligible, allowing straightforward servo tuning and high acceleration for semiconductor tooling, electronics assembly, and metrology equipment.

The active coil measures 206.8 mm long, 25 mm wide, and 98.5 mm tall, giving a compact rectangular profile that fits narrow machine spaces. With a mass of 0.52 kg, the lightweight mover minimizes moving inertia. When supplied with a continuous current of 1.6 Arms, the winding produces 88 N of steady thrust while dissipating heat through the epoxy-potted windings. For short-duty events, the coil can accept a crest current of 7 Arms and generate up to 400 N of peak force, enabling fast indexing moves. The force constant is 57 N-m/Arms, so the drive can estimate output force from commanded current.

The back electromotive force constant is 46.5 Vpk/m/s, which lets the drive calculate voltage headroom at target speeds. Copper windings present a DC resistance of 17.2 ohms and an inductance of 6 mH, which influence current rise time and servo bandwidth. The associated magnet track weighs 12.2 kg per meter, which is useful when determining cable-carrier and support-bearing loads. Average heat is removed through 0.629 °C/W thermal resistance, and the coil can continuously convert 553 W of electrical power into motion without exceeding its temperature limit.
