Abstract

Beskyttelsesanordning (70) for å tilveiebringe beskyttelse mot et eksternt magnetfelt i et drivsystem (60) som befordrer rotasjonsdrift mellom to mekaniske organer (28, 44) mndt en akse ved magnetisk kobling, idet drivsystemet innbefatter minst to aksialt magnetiserte elementer (62a, 62b, 64a, 64b) som begge er festet til minst ett av de mekaniske organene og er utfonnet for å vekselvirke med hverandre, idet de magnetiserte elementene er aksialt forskjøvet, idet beskyttelsesanordningen omfatter to deler (72, 74; 92, 94; 96, 98) laget av magnetisk materiale som omslutter drivsystemet, idet hver av delene har en minste radial utstrekning som er større enn de magnetiserte elementenes radiale utstrekning, idet beskyttelses- anordningen er karakterisert ved at de to delene (72, 74; 92, 94; 96, 98) laget av magnetisk materiale danner et akse-rom (76) mellom seg for å redusere det eksterne magnetfeltets gradient ved drivsystemet, og ved at de har en aksial utstrekning som er slik at de omgir drivsystemet aksialt.
