Magnetic modules with magnetically actuated and unactuated fixed surfaces

摘要

Two front fixed surfacesA magnetic module (10) having aIt can be magnetically actuated and inoperable by reversal of magnetic flux.Module (10)Comprising first (16) and second (17) fixed coresEachEach front fixed surfaceA plurality of polarity elements (26) defining aBack surfaceIn addition toA first plurality of permanent magnets (29) disposed between adjacent polar elementsPolarity (n) of permanent magnetS)In contact with the lateral plane of the single polarity elementIn each fixed coreAlternately, polarities of reverse polarity induction polarity are generated.A movable magnetic unit (18) for reversal of magnetic fluxTwo fixed magnetic cores17)Two fixed magnetic cores17Pole opposite polarity (n) opposite toIs configured with a second plurality of permanent magnets (30) having an alternative to s;A movable magnetic unitCan be moved between the first and second actuation positions for the reversal of the flux;Front of the fixed module (10)One or both of them are magnetically activated and deactivated.Diagram
