Product Description:

The AL2009-0001-0001 is a coil unit from the AL Linear Motors series produced by Beckhoff. Classified within the company’s linear servo motor product range, it generates direct thrust along a magnetic track to move machine slides or gantry axes without mechanical transmissions. By producing force electromagnetically rather than through ball screws or belts, the unit supports high-speed positioning tasks in industrial automation. Direct linear motion also eliminates transmission components that could introduce backlash into the motion system.

The motor delivers a continuous thrust of 300 N while drawing a steady phase current of 6.45 A. For rapid acceleration or short overloads, it can reach a peak thrust of 675 N at up to 19.6 A, allowing fast indexing under transient loads. When paired with a matched magnetic track, the carriage can attain a linear speed of 7 m/s. During operation, the stator dissipates 225 W of power. The winding has an inductance of 18 mH and a resistance of 2.42 Ω, which set the electrical time constants that the drive must regulate. A magnetic attraction force of 1,325 N acts between the coil unit and the permanent-magnet secondary, so the mounting hardware must withstand this preload.

The unit incorporates nine coils wound in a speed-winding pattern and spaced at a pole pitch of 24 mm. Its overall width is 80 mm, and the coil assembly weighs 2.0 kg, helping reduce moving mass on multi-axis pick-and-place machines. Thermal management relies on conduction through the mounting plate. With a thermal resistance of 0.32 °C/W and a thermal time constant of 77 s, the temperature rises gradually without water cooling. The motor constant is 570 N²/W, indicating the relationship between generated force and power loss. Electrical terminations use M23 power and D-Sub feedback connectors, providing direct connections to compatible Beckhoff servo drive equipment.
