Product Description:

Kollmorgen manufactures the IC11050A1TSP1 linear motor coil for the IC Ironcore Direct Drive Motors series. As an iron-core direct drive mover, it partners with a magnet track to create thrust without mechanical transmission, allowing precise, backlash-free positioning in industrial automation stages, gantries, and pick-and-place axes. With its laminated core, the coil delivers high force density while keeping cogging low, making it suitable for scanning tables and semiconductor handling equipment.

The motor can deliver a continuous thrust of 256 N at 25 °C. Sustaining that output requires only 4.35 Arms, so drives with moderate current capability can run the axis efficiently. A back-electromotive-force constant of 48.8 Vpk/(m/s) indicates the voltage the coil returns for each meter per second of speed, which is important when sizing the amplifier voltage bus. Electrical behavior is further characterized by an inductance of 28 mH and a DC winding resistance of 2.68 Ω; together, these values influence current ripple, time constants, and resistive heating. The copper windings weigh 3.6 kg, contributing to thermal inertia while keeping moving mass low.

For short bursts, the coil withstands a peak thrust of 641 N when momentarily driven with up to 15.2 Arms. These overload ratings support rapid acceleration or disturbance rejection during demanding motion profiles. The magnet track under the coil exerts an attractive normal load of 2.43 kN, so linear guides must support that force to prevent deflection. Thermal management is aided by a thermal resistance of 0.99 °C/W, indicating how quickly heat moves from the windings to the mounting surface. The assembly rides over a magnet rail that adds 7.5 kg per meter to the axis mass, and the moving element maintains a 58.3 mm overall height above the track, allowing the motor to fit into compact machine frames without sacrificing stroke or stiffness.
