Abstract:
Método que busca conseguir un hilo magnético que permita trabajar a más alta frecuencia que el Hierro-Silicio y generar más inducción que la Ferrita, siendo de costes bajos, comprende las etapas de: -deposición (5) de una capa de hierro puro en la parte exterior del hilo -Trefilado en frío (6) para reducir el diámetro y orientar la veta. -Polarización magnética (7) -Recocido distensionador (8) bobinando el hilo en un carrete refractario (11), -decapado y limpieza (9) en una cuba. -Esmaltado y secado (10), Adicionalmente se le puede someter al hilo tras el recocido distensionador y antes del esmaltado y secado (10) a un proceso de niquelado. El hilo obtenido por el método anterior comprende: un núcleo o alma (1) de acero, una capa de Hierro puro (2) que recubre el núcleo o alma (1) y una capa aislante (4), pudiéndose disponer entre la capa de Hierro puro (2) y la capa aislante una capa de Hierro-Níquel (3),

Abstract:
An inductive device comprises a magnetic core including a portion of a plurality of wires, at least one electric winding extending around the magnetic core, each of the plurality of wires substantially encircling the at least one electric winding, and at least one biassing magnet disposed adjacent the plurality of wires to provide a bias magnet flux for offsetting a flux generated by a direct current component flowing in the winding.
Abstract:
A high voltage stationary electromagnetic device comprising a core (7-9) of magnetic material having a relative permeability greater than 1 and current-carrying winding means (1-3) for generating an H-field. The core (1-3) is constructed and arranged so that, in use of the core assembly, current carried by the winding means gives rise to a B-field in the core which substantially follows the H-field.
Abstract:
A transformer core has at least one limb extending between a pair of yokes. The at least one limb and yokes meet at core joints. The core joints are rounded to provide a curved magnetic flux path that does not have hard directional changes. The core joints are formed of laminations of flexible grain-oriented electrical steel fibers embedded in a non-magnetic material to provide the oriented magnetic flux direction from the at least one limb to the yokes of the core.
Abstract:
The flexible soft magnetic core (1) includes parallel continuous ferromagnetic wires (4) embedded in a core body (2) made of the polymeric medium (3). The continuous ferromagnetic wires (4) extend from one end to another end of said core body (2), are spaced apart from each other and are electrically isolated from each other by the polymeric medium (3). The method for producing the flexible soft magnetic core (1) comprises embedding continuous ferromagnetic wires (4) into an uncured polymeric medium (3) by means of a continuous extrusion process, curing the polymeric medium (3) with the continuous ferromagnetic wires (4) embedded therein to form a continuous core precursor (10), and cutting said continuous core precursor (10) into discrete magnetic cores (1).
