Product Description:
The AL2018-0000-0000 is a coil unit developed by Beckhoff for the AL Linear Motors series. As a primary mover operating along a fixed magnet track, the unit produces direct linear thrust for gantries, pick-and-place axes, and process machines that require high acceleration without gears or ball screws. Direct drive operation removes mechanical transmission components that can introduce backlash, wear, and positioning errors. The segment is supplied without connectors, allowing machine builders to route custom cabling directly to the drive controller while maintaining a compact installation height. This configuration also gives system designers flexibility when arranging the motor cable and temperature sensor connections inside the machine.
The electromagnetic stack has 18 standard windings and operates continuously at a phase current of 6.45 A, generating a sustained thrust of 600 N when cooled by ambient air. Copper and iron losses under this load reach 450 W, which is consistent with a winding resistance of 4.82 Ω and a per-phase inductance of 36 mH. The motor uses a uniform pole pitch of 24 mm and requires an air gap of 0.5 mm between the stator and magnet assembly. A motor constant of 1140 N²/W indicates the relationship between generated force and electrical power loss. An integrated KTY83-122 sensor and a 1 kΩ PTC provide temperature monitoring so the drive can reduce output if the winding temperature rises excessively.
At maximum excitation, the mover delivers a peak thrust of 1350 N for brief periods of high acceleration. The magnetic attraction force is 2450 N, so the supporting structure and linear guides must withstand the load acting between the coil unit and steel magnet track. Thermal behavior is characterized by a resistance of 0.16 °C/W and a time constant of 77 s, indicating how the 3.8 kg coil responds to heat generated during operation. The magnetic plate adds 3.8 kg per meter of travel to the installed track assembly. Because the unit does not use water cooling, adequate airflow must pass across the 80 mm module face to remove heat, limit continuous power loss, and protect the winding insulation.
