Abstract

NÚCLEO DE ESTATOR, E, MÁQUINA ELÉTRICA ROTATIVA. A presente invenção é um núcleo de estator (21) provido com uma pluralidade de núcleos divididos (30). A pluralidade de núcleos divididos (30) é configurada dispondo em camadas peças de núcleo (40) compreendendo chapas de aço elétrico. As chapas de aço elétrico são chapas de aço elétrico predeterminadas. Tanto a direção radial dos dentes (41) quanto a direção de extensão das partes de trás do núcleo (42) das peças de núcleo (40) de pelo menos um núcleo dividido (30) dentre a pluralidade de núcleos divididos (30) são arranjadas ao longo de uma direção em que as chapas de aço elétrico têm excelentes características magnéticas.
