Abstract

Dispositivo de proteccion (70) contra un campo magnético exterior de un sistema (60) de impulsion de acoplamiento magnético que gira alrededor del eje de dos miembros mecánicos (28, 44). El sistema impulsor comprende cuando menos dos elementos axialmente magnetizados (62a, 62b, 64a, 64b), cada uno integral con uno de los miembros mecánicos y que interaccionan entre sí, con los elementos magentizados estando axialmente desplazados. El dispositivo comprende dos partes (72, 74, 92, 94, 96, 98) de material magnético que rodea el sistema de impulsion, cada una de las partes tiene una extension radial mínima mayor que aquella de los elementos magentizados. El dispositivo está caracterizado en que las dos partes (72, 74, 92, 94, 96, 98) de material magnético juntas forman un espacio (76) axial para reducir el gradiente del campo magnético exterior en el sistema de impulsion, con su extension axial causando el encerramiento axial del sistema de impulsion.
