Abstract
EL PAQUETE (1) DE CHAPAS DE UN TRANSFORMADOR O UNA BOBINA SE CONFIGURA A TRAVES DE CHAPAS (2,3) DE NUCLEO EN FORMA DE U, QUE DESCANSAN UNA AL LADO DE LA OTRA Y ESTAN SUJETAS UNA CON OTRA DE TAL MODO QUE FORMAN UN PAQUETE DE NUCLEO EN FORMA DE E. LAS PATILLAS (14,15) RESPECTIVA CORTAS DE CADA CHAPA EN U FORMAN CONJUNTAMENTE LA PATILLA MEDIA DE LA CHAPA EN FORMA DE E, Y SE COMPLETA EL PAQUETE DE CHAPAS DE NUCLEO DE FORMA RESPECTIVA A TRAVES DE UNA CHAPA (4) DE CONCLUSION EN FORMA DE I. LAS CHAPAS EN FORMA DE U ESTAN UNIDAD POR EJEMPLO A TRAVES DE SOLDADURA UNA CON OTRA. LA COMPOSICION DEL PAQUETE DE CHAPAS EN FORMA DE E A PARTIR DE NUCLEO DE CHAPAS EN FORMA DE U CONSIGUE UNA LIBERTAD ESENCIALMENTE MAYOR EN EL PROCESO DE ESTAMPACION, YA QUE SOLAMENTE DEBEN SER ESTAMPADAS EN FORMA DE U. ESTO PERMITE QUE LA ESTAMPACION SE EJECUTE DE TAL MODO QUE LAS PATILLAS DE LA U SE DISPONGAN EN DIRECCION DE LAMINADO DE LAS TIRAS DE MATERIAL DE CHAPAS DE NUCLEO. CON ELLO SE CONSIGUE UNAS PROPIEDADES MAGNETICAS ESENCIALMENTE MEJORADAS DE LOS PAQUETES DE CHAPAS DE NUCLEO.
