TLDR
In this article, a wound iron core was obtained by placing an insulating layer every between a plurality of layers of amorphous magnetic thin ribbons having no surface insulating films.Abstract:
PURPOSE:To obtain a wound iron core having an excellent space factor as well as a small interlayer eddy-current loss by effecting insulation by placing an insulating layer every between a plurality of layers of amorphous magnetic thin ribbons having no surface insulating films. CONSTITUTION:One or a plurality of layers of amorphous magnetic thin ribbons 3 each coated with surface insulating films 4 of glass, phosphate or the like as insulating layers are placed every between a plurality of amorphous magnetic thin ribbons 2 having no surface insulating films so as to divide them into blocks electrically insulated from each other, to constitute a wound iron core 1. Thereby, the characteristics of the amorphous magnetic thin ribbon, a high magnetic permeability and a small loss, are made use of, and the interlayer eddy-current loss can be reduced without a bad influence on the space factor.read more

TL;DR: In this article, a method to remove the layer short of a cut surface and reduce the high-frequency iron loss of a highfrequency core by a method wherein the laminated core formed by laminating a magnetic thin belt having high specific permeability and by impregnating with resin between the layers is cut, and the cut surfaces of the core body are finished to the surfaces removed with flashes generated at cutting time.
Patent
Amorphous iron core transformer
TL;DR: In this paper, the authors propose an amorphous iron core transformer in which magnetic flux concentration in a magnetic circuit section, an increase in eddy current loss, stress generated owing to a difference in coefficient of thermal expansion from an implement for deformation prevention in annealing, etc., are suppressed.
