Heavy forces compensate for a device for linear motor driven sliding element

摘要

The invention concerns a mechanism (20) for compensating the gravitational force (29) acting on a slider (32) of a linear motor (26), in particular of an electro-magnetic direct linear motor (27), and acting on a load to be carried and moved by the slider. To compensate for the gravitational force (29), the mechanism (20) exhibits a spring element (28), which exerts an elastic restoring force (30) against the gravitational force (29) on the slider (32).
