"A Design Concept of Linear-Type Gravity Compensation Using Permanent-M" by Xiangxian Zeng, Chin Hsing Kuo et al.
This paper presents a design concept of using permanent magnets for linear-type gravity compensation. The basic idea is to let one permanent magnet (or a group of magnets) carry out the weight to move against a group of another permanent magnets that are fixed on the ground. The fixed magnets are arranged in a special array configuration so that the interactive forces among the magnets can effectively cancel the weight within a certain range of heights. While the concept uses common magnets with...
