摘要

The device (1) has a stationary drive unit (3) for defining a running path for a movable rotor (2) and comprising a set of individual drive elements (30) that are arranged in series. An articulation link (5) i.e. ball-and-socket joint, is provided between the adjacent drive elements. The articulation link comprises cylindrical surfaces or partial cylindrical surfaces. The rotor comprises a set of individual rotor elements that are arranged in series, where another articulation link (6) is provided between the adjacent rotor elements. The rotor elements comprise permanent magnets.
