Abstract
A passive magnetic constant-force apparatus comprises a geometry and arrangement of permanent magnets, ferromagnetic components, and non-magnetic structural components. The apparatus is easily and precisely adjustable, cost-effective, with a high load capacity, and with minimal parasitic forces. The apparatus is suitable for use as a counterbalance for vertical linear motion applications and may be integrated with or attached to a linear motion stage.
