Product Description:

The AL2015-0001-0001 moving coil is produced by Beckhoff within the AL Linear Motors series. As a coil unit for a linear servo motor, it interacts with a stationary magnet track to generate direct linear thrust for fast, repeatable positioning in machine tools, handling robots, and packaging systems. The compact active element eliminates the need for mechanical transmissions in automated axes, reducing the number of components between the motor and the load.

It is designed for sustained operation at a continuous phase current of 10.75 A, producing a continuous thrust of 500 N when cooled by ambient air while dissipating 375 W through copper and core losses. During rapid indexing, the coil can deliver a peak force of 1125 N from a momentary winding current of 32.7 A. This transient capacity is balanced against a magnetic attraction force of 2075 N acting toward the magnet plate. Travel speed can reach 7 m/s, aided by the 24 mm pole pitch, 10.8 mH inductance, and 1.44 Ω resistance, which support a quick current rise. Fifteen individual coils are arranged within the 80 mm-wide housing. The assembly operates without water cooling and relies solely on forced or natural airflow.

The motor constant is 950 N²/W, indicating the relationship between squared thrust and thermal power loss in the coil. Heat moves through the laminations with a thermal resistance of 0.19 °C/W, and the temperature rises according to a 77-second thermal time constant before reaching steady state. Electrical commutation is supported by a voltage constant of 26.87 V/m/s, allowing the drive to calculate back electromotive force at a given speed. The coil has a mass of 3.2 kg and maintains a working air gap of 0.5 mm from the magnet rail. Power and feedback signals are routed through integrated M23 and D-Sub connectors for connection to the associated drive and feedback equipment.
