The linear servomotors are available in two versions: the AL2xxx, with iron core and varying magnetic track width, and the ironless AL38xx.
AL20xx
Linear Servomotors
iron core motor (magnetic path width 80 mm) motor with highest power density
AL24xx
Linear Servomotors
iron core motor (magnetic path width 50 mm) for installation in compact mechanics
AL28xx
Linear Servomotors
iron core motor (magnetic path width 130 mm) for applications with highest demands on force and stability
AL38xx
Linear Servomotors
ironless motor (magnetic yoke width 48 mm) for highest demands on synchronism, dynamics and precision
