SYSTEM FOR CONTROLLING MAGNETIC FLUX OF A MULTI-POLE MAGNETIC STRUCTURE

摘要

A system for controlling flux of a multi-pole magnetic structure includes a movable magnetic circuit where the position of the moveable magnetic circuit relative to the multi-pole magnetic structure determines the flux emitted by the magnetic structure. The moveable magnetic circuit may be configured to have a tipping movement, a translational movement, and/or a rotational movement relative to the multi-pole magnetic structure.

1. A magnetic system, comprising:
a magnetic structure comprising a plurality of magnetic sources having a polarity pattern comprising first and second polarities; a magnetic circuit; and a mechanism configured to move at least one of said magnetic structure or said magnetic circuit to a plurality of alignment positions, a first alignment position of said plurality of alignment positions resulting in a first amount of flux being directed to a ferromagnetic surface, said first amount of flux corresponding to a maximum attachment force, a second alignment position of said plurality of alignment positions resulting in a second amount of flux being directed to said ferromagnetic surface, said second amount of flux corresponding to a minimum attachment force.
