Product Description:
The AL2418-0000-0001 is a moving-coil primary section produced by Beckhoff for the AL Linear Motors series. As part of a linear servo drive, this component converts controlled armature current into direct thrust along a magnet track. It enables machines to position loads precisely and at high speed without rotary-to-linear mechanisms in automated assembly, packaging, or inspection cells. The direct-drive arrangement also eliminates mechanical transmission components that could introduce backlash between the motor and the moving load.
The motor delivers a continuous thrust of 360 N while drawing a continuous phase current of 4.56 A; these paired ratings indicate the steady-state workload the coil can handle without exceeding its 296 W power loss limit. For short accelerations, the drive may command a peak current of 12.30 A, and the winding produces a motor constant of 570 N²/W, indicating how efficiently electrical losses are converted into force. Under these conditions, a carriage can reach a linear speed of 4.5 m/s, provided the 0.5 mm air gap to the magnetic track is maintained. The motor uses a normal winding with an inductance of 46 mH and a resistance of 7.2 Ω, which influence current rise time and voltage demand. A 24 mm pole pitch and an 18-coil layout establish the magnetic wavelength used by the controller for commutation.
Dynamic thrust can reach 720 N, which must be considered with the 1,300 N magnetic attraction force acting between the coil and the iron rail. The back-EMF coefficient of 45.96 V/m/s helps determine the required DC-bus voltage for full-speed operation. A thermal resistance of 0.25 °C/W indicates the expected temperature rise when optional water cooling is not used. Mechanical integration is aided by a component width of 50 mm. Integral M23 and D-Sub connectors route power, Hall signals, and thermal sensor connections through a single harness, while a power constant of 79 N/A relates phase current to the generated linear force.
