Abstract

Transformatorkjerne bestående av overliggende grupper av strimler av amorft stål viklet rundt kjernens vindu, hvor hver gruppe omfatter en indre seksjon og en ytre seksjon anbragt i et overliggende forhold, og hvor hver seksjon omfatter mange tynne lag av strimler av amorft stål. Hvert av lagene i en seksjon har en lengdedimensjon målt mellom de tverrgående kanter av laget, plassert ved motsatte ender av seksjon-en. Lagene i den indre seksjon av en gruppe har i det vesentlige like lengd-er, og lagene i den ytre seksjon av gruppen har i det vesentlige like lengd-er, som er større enn lengden til lagene i den indre seksjon. Ved en ende av hver gruppe er de tverrgående kanter på alle lagene i gruppen i hovedsak på linje slik at det dannes en glatt kant. På den andre enden av gruppen (i) er de tverrgående kanter på lagene i den indre seksjon anbragt slik at det dannes en skrå kant for den indre seksjon, (ii) de tverrgående kanter på lagene i den ytre seksjon er anbragt slik at det dannes en skrå kant for den ytre seksjon, og (iii) den skrå kant på den ytre seksjon over-lapper den skrå kant på den indre seksjon.
