Abstract

La presente invención muestra un método para la clasificación de chapas magnéticas utilizadas para la producción de una máquina eléctrica, en donde la chapa se encuentra en forma de un rollo de cinta (1), caracterizado porque el rollo de cinta (1) se genera por medio de un devanado (2) de excitación alimentado por un dispositivo (5) de alimentación un flujo magnético variable en el tiempo, que provoca una variación de la forma del rollo de cinta (1) y pérdidas magnéticas, porque la variación de la forma y/o las pérdidas magnéticas se miden por medio de un dispositivo de medición (3, 6, 23) y la señal de medición (21, 22, 24) obtenida a este respecto se suministra a un dispositivo de evaluación (4), y porque el dispositivo de evaluación (4), usando la señal de medición (21, 22, 24), realiza una categorización de la chapa magnética con respecto a la emisión de ruido y/o las pérdidas magnéticas.
