Product Description:

The IC11050A1TRP1 is a moving-coil assembly in Kollmorgen’s IC Ironcore Direct Drive Motors series. Designed for flatbed and gantry axes, the unit converts three-phase current into linear thrust along a permanent-magnet track, removing gears and ball screws from the motion path. By integrating directly with the load carriage, this ironcore motor simplifies positioning systems that demand high force density and sub-micron repeatability in semiconductor handling, electronics assembly, and packaging lines. Because the force is generated without rotary transmission elements, the axis avoids backlash and mechanical compliance that can reduce placement accuracy.

Under continuous duty at 25 °C, the coil delivers 256 N of steady thrust while drawing 4.35 Arms, which allows the amplifier to be sized for sustained workloads. The phase-to-phase inductance is 28 mH, and this affects current rise time and the bandwidth available to the servo loop. Copper winding resistance measures 2.68 Ω, which sets the baseline for I²R losses and helps predict temperature rise through the assembly’s 0.99 °C/W thermal resistance to the mounting plate. Heat must pass into the mounting surface, so the supporting structure serves as the primary path for continuous thermal dissipation. The coil has an active length of 200.2 mm, a width of 85 mm, and a height of 58.3 mm, so it fits narrow machine envelopes while still providing enough surface area for conduction cooling. The 3.6 kg moving mass limits inertial load on the guide bearings and helps the axis respond quickly to command changes.

For transient moves such as rapid indexing, the motor can reach 641 N of peak thrust when the drive supplies up to 15.2 Arms for short intervals. A back electromotive force constant of 48.8 Vpk/m/s establishes the voltage the amplifier must overcome at speed, while the inherent iron attraction between coil and track is 2.43 kN, which affects bearing selection and structural stiffness. That attraction load must be absorbed by the guide system so the air gap stays uniform during rapid motion and force reversal. The magnet way adds 7.5 kg per meter to the axis payload, which influences frame sizing and dynamic tuning. This added mass is stationary along the axis, but it still affects support requirements and overall machine rigidity during high-speed positioning.
