Abstract

chapa de aço elétrico não orientado, núcleo de motor, e, métodos para fabricar uma chapa de aço elétrico não orientado e um núcleo de motor. é provida uma chapa de aço eletromagnético não orientado que é distinguida por ter uma composição química prescrita. a chapa de aço eletromagnético não orientado também é distinguida por, em uma seção transversal que é paralela a uma superfície laminada da chapa de aço eletromagnético não orientado, a razão de área de uma estrutura cristalina a, que é formada por grãos de cristal que têm um tamanho de grão de pelo menos 100 µm, ser dentre 1% a 30%. a chapa de aço eletromagnético não orientado também é distinguida pelo tamanho médio de grão de uma estrutura cristalina b, que não é a estrutura cristalina a, não ser mais de 40 µm. a chapa de aço eletromagnético não orientado também é distinguida pela dureza vickers hva da estrutura cristalina a e a dureza vickers hvb da estrutura cristalina b satisfazerem a expressão 1 ((hva2+hvb2)/2-(hva+hvb)2/4=7,0).
