Product Description:

Beckhoff supplies the AL2024-0001-0000 as a coil unit in the AL Linear Motors series. This product belongs to the manufacturer’s linear servo motor range and is intended to generate direct thrust along a magnet track, eliminating rotary-to-linear conversions in automated machinery. Used with matching secondary parts and drives, the unit provides precise, repetitive positioning for gantries, pick-and-place axes, and high-speed transport stages in industrial production lines.

The motor delivers a continuous thrust of 800 N while drawing a continuous phase current of 17.20 A. For short duty cycles, it tolerates a peak current of 52.0 A, resulting in rapid acceleration and a peak force capability of 1,800 N. Heat generated under rated loading produces 600 W of continuous power loss that must be removed by convection because the unit does not have water cooling. Magnetic and mechanical alignment are maintained by an operational air gap of 0.5 mm between the coil face and the permanent-magnet track, a tolerance that influences achievable stiffness and attraction forces. The coil section weighs 5.2 kg, so the moving mass remains low enough for dynamic cycles when the track is mounted in a stationary position.

Twenty-four individual windings arranged on a 24 mm pole pitch interact with the magnet rail, producing 3,400 N of constant magnetic attraction, while a motor constant of 1,520 N²/W relates electrical loss to force production. Electrical behavior is shaped by a winding inductance of 6.8 mH and a winding resistance of 0.92 Ω, which are important parameters for drive sizing and current-loop bandwidth. Thermal performance relies on a thermal resistance of 0.12 °C/W and a thermal time constant of 77 s, which govern the temperature rise during sustained moves. The 80 mm wide speed-winding variant is supplied without connectors, allowing application-specific cabling to be soldered or crimped directly onto the coil leads.
