Abstract
A method for operating a linear motor assembly includes: open-loop controlled introduction of electric energy to a first stator segment provided with solenoids for an open-loop controlled provision of a magnetic field for a permanent magnet arrangement of a conveying means for a generation of drive forces, and closed-loop controlled introduction of electric energy to a second stator segment provided with a measuring device for a detection of a position of a conveying means and with solenoids for a closed-loop controlled provision of a magnetic field acting on the conveying means, wherein a controlling device effects a temporary switch-over of the second stator segment from a closed-loop controlled state to an open-loop controlled state at a transition of the conveying means from the first stator segment to the second stator segment, and/or at a transition of the conveying means from the second stator segment to the first stator segment.
