Abstract

Un dispositivo de núcleo magnético perfeccionado para una máquina dinamoeléctrica, en la que el núcleo consta de una pluralidad de chapas sujetadas entre sí bajo presión, unos medios de percepción de flujo empotrados en dicho núcleo, comprendiendo dichos medios de percepción una bobina plana de múltiples espiras situada entre dos chapas adyacentes de entre dicha pluralidad de chapas y paralela al plano de dichas chapas próximo a la región extrema del núcleo en una posición apropiada para percibir el flujo magnético axial, no teniendo dicha bobina material magnético que se extienda a través de las espiras de la misma, teniendo dicha bobina unos cables conductores planos que se extienden desde ella y entre dichas dos capas adyacentes hasta el exterior de dicho núcleo magnético, y medios para encerrar con acción de aislamiento dicha bobina y para soportar el contacto a presión de dichas capas adyacentes, teniendo dichos medios un grosor total mayor que el de dicha bobina.
