Abstract

Se proporciona un patrón de formación de ranuras lineales con el que se puede obtener tanto un efecto de reducción del factor de construcción como una alta densidad de flujo magnético. En una lámina de acero eléctrico de grano orientado que tiene una pluralidad de ranuras lineales que se extienden en una dirección que cruza una dirección de laminación de la lámina de acero sobre una superficie de la lámina de acero, una superficie de la lámina de acero entre las ranuras lineales tiene un defecto rebajado que está rebajado desde la superficie, una fracción de volumen del defecto rebajado en la lámina de acero es 0.0025% en vol. o más y 0.01% en vol. o menos de una lámina de acero sin el defecto rebajado, y las porciones discontinuas que interrumpen la extensión de las ranuras lineales se proporcionan con una frecuencia de 30 o más y 200 o menos por metro cuadrado de la lámina de acero.
