ABSTRACT:
A conveying installation with a linear motor drive including a stator placed along a travel path and at least one conveyor unit guided along the stator in a constrained manner. The stator is divided into a plurality of stator portions. To each stator portion is assigned a braking device whose operation is dependent upon the current supply to a stator. The conveyor units are guided spaced apart by a predetermined distance. If the current supply fails, the braking devices are actuated and stop the movements of the conveyor units.
