Abstract
In order to enable safe deceleration of a transport unit of a long-stator linear motor, wherein in a normal mode a plurality of drive coils of the long-stator linear motor are energized in such a way that a magnetic field coupled to a transport unit is moved along a direction of motion in order to move the transport unit along the direction of motion, according to the invention a switching to a controlled short-circuit mode is performed during the braking operation of the transport unit, in which at least some of the drive coils are short-circuited at least over a first time interval in said mode.
