Product Description:
The IL18100A3TRC4 is an ironless direct-drive linear motor coil produced by Kollmorgen within the IL Ironless DDL Motors series. Designed for gantries, pick-and-place axes, and other industrial automation stages, this moving coil interacts with a stationary magnet track to create thrust without mechanical transmission components, delivering precise force and smooth motion. The coil operates directly from a servo drive that regulates current to control force and velocity, and because the forcer contains no iron, cogging is eliminated, improving trajectory accuracy.
The electromagnetic constants set the coil’s dynamic range. A force constant of 57 N-m/Arms links commanded current to axial thrust, while the continuous current limit of 3.7 Arms supports a continuous force of 211 N at 25 °C without exceeding thermal limits. For rapid positioning or short duty bursts, the drive may supply 21 Arms, producing up to 1200 N of peak force for acceleration. Rated power is 1376 W, so drive sizing must accommodate this thermal load together with the coil’s 4.9 Ω phase-to-phase resistance. These values influence voltage demand, current-loop bandwidth, and achievable move profiles under closed-loop control.
Other parameters affect mechanical integration and temperature rise. The back-EMF constant of 46.6 Vpk/m/s sets the voltage generated during motion, influencing the servo drive’s DC bus margin. Physical size is fixed by a coil length of 302.8 mm, a width of 34 mm, and a height above the magnet way of 148.5 mm; along with a coil mass of 1.1 kg, these dimensions affect inertia and payload calculations. Electrical dynamics are guided by an inductance of 2.33 mH, which shapes current ripple, and a thermal resistance of 0.29 °C/W, which links power dissipation to temperature rise. During installation, the magnet way adds 27.3 kg per meter, so the supporting machine structure must handle that load without deflection.
