Abstract

"NúCLEO DE TRANSFORMADOR". Um núcleo de transformador ou indutor de material magnético tem três membros (6,8,10) interligados por culatras. O núcleo compreende circuitos (12,14,16) de fios e/ou tiras de material magnético, onde cada um dos circuitos compõe parte de dois dos membros. Os circuitos compondo parte de duas porções de membro diferentes são intercalados em uma porção de membro comum. Isso proporciona a estabilidade mecânica e boas propriedades magnéticas para o núcleo.
