Beschreibung
Zusammenfassung:	A weight compensating device includes a stator and a translator. The translator is movable relative to the stator along a movement axis. The translator includes a first permanent magnet arrangement with an axial magnetization. The stator includes a second permanent magnet arrangement that radially surrounds the first permanent magnet arrangement. The stator includes a third permanent magnet arrangement that is arranged coaxially below the first permanent magnet arrangement and that has an axial magnetization that is aligned in inverse fashion with respect to the axial magnetization of the first permanent magnet arrangement. The stator includes a magnetic body arrangement that is arranged coaxially above the first permanent magnet arrangement. The first permanent magnet arrangement, the second permanent magnet arrangement, the third permanent magnet arrangement and the magnetic body arrangement form a magnetic unit and, in interaction with one another, form a compensating force that counteracts the weight acting on the translator.
