Abstract
A mechanism for compensating the gravitational force acting on a slider of a linear motor, in particular of an electro-magnetic direct linear motor, and acting on a load to be carried and moved by the slider. To compensate for the gravitational force, the mechanism exhibits a spring element, which exerts an elastic restoring force against the gravitational force on the slider.
