Product Description:

The IC11050Q1TSP2121 is a coil assembly manufactured by Kollmorgen for the IC Ironcore Direct Drive Motors series. Designed for gantry tables, pick-and-place modules, and metrology stages, the coil produces controlled linear force when energized against a matching magnet way, providing rapid positioning without gears, ball screws, or belts. Its ironcore construction concentrates magnetic flux in a compact profile that suits tight machine frames and thermally managed platens.

The coil delivers a continuous thrust of 256 N at 25 °C while drawing 4.35 Arms. This operating point is supported by a thermal resistance of 0.99 °C/W, which indicates the temperature rise per watt dissipated into the mounting surface. A force constant of 59.7 N/Arms links commanded current to generated force, and the electrical behavior is influenced by an inductance of 28 mH together with a 2.68 Ω DC resistance that contributes to steady-state copper losses. The 48.8 Vpk/m/s back-EMF constant gives a voltage proportional to travel speed, and the motor constant of 29.9 N/√W reflects the force available for each root watt of loss. The coil has an active length of 200.2 mm, a width of 85 mm, a height of 58.3 mm above the magnet way, and a mass of 3.6 kg, which helps determine carriage geometry and heat transfer requirements.

During acceleration, the unit can be driven to a peak force of 641 N with up to 15.2 Arms of current, allowing short high-speed moves before returning to the continuous rating. The magnetic interface creates an attractive preload of 2.43 kN, so the linear bearing system must support that normal load while maintaining smooth travel. Machine layouts should also account for the magnet way mass of 7.5 kg/m when sizing support structures and moving assemblies. Proper heat sinking and current limiting help prevent thermal runaway during repetitive indexing.
