Abstract
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 electromagnetic 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).
Claims11
A mechanism for compensating the gravitational force (29) acting on a slider (22, 32) of a linear motor (26), in particular of an electromagnetic direct linear motor (27), and acting on a load to be carried and moved by the slider (22, 32), capable of moving along a travel path (21),
- characterized in that
- a spring element (28) is provided which exerts on the slider (22,32) an elastic restoring force (30) opposite the gravitational force (29).
