Product Description:

The AL2024-0001-0001 linear primary section is manufactured by Beckhoff for the AL Linear Motors series. As part of the company’s linear servo motor range, it delivers direct electromagnetic thrust to move machine axes without ball screws or belts, simplifying high-speed pick-and-place, gantry cutting, and packaging equipment. The unit forms the moving portion of a modular track system, accepting current from a servo inverter and reacting against a permanent-magnet secondary to generate force along the travel path.

During continuous operation, it develops a force of 800 N with forced-air cooling at a continuous current of 17.20 A, while power dissipation remains 600 W with a thermal resistance of 0.12 °C/W. Magnetic attraction toward the iron rail reaches 3400 N, a force that must be counteracted by the mechanical design. Its maximum rated velocity is 7 m/s, which is achievable when the 0.5 mm working air gap and the 24 mm pole pitch are maintained. The motor constant of 1520 N²/W relates the developed thrust to copper loss and indicates cooling efficiency. Heat is removed solely by forced air, and water jackets are not provided. Electrical termination is handled through factory-installed M23 and D-Sub connectors, while the 80 mm wide housing carries the speed winding variant for reduced inductance.

For short bursts, the mover can deliver a peak force of 1800 N when driven with 52.0 A, permitting rapid acceleration of payloads. The voltage constant is 26.87 V/m/s, indicating the back electromotive force that the inverter must overcome as speed rises. Twenty-four coils provide an inductance of 6.8 mH and a phase resistance of 0.92 Ω, which are parameters used for current-loop tuning. A thermal time constant of 77 s shows that the coil temperature changes slowly, enabling duty cycles with significant but brief overloads before thermal equilibrium is reached.
