Abstract

SE PRESENTA UN METODO PARA FABRICAR UN NUCLEO MAGNETICO LAMINADO SOLDANDO MEDIANTE LASER SUCESIVAS LAMINAS, LAS LAMINAS DEL NUCLEO SE APILAN UNAS SOBRE OTRAS PARA FORMAR UN CUERPO APILADO DE LAMINAS DEL NUCLEO, Y MIENTRAS EL CUERPO APILADO DE LAS LAMINAS QUE FORMAN EL NUCLEO SE MUEVEN PASO A PASO EN UNA DIRECCION DE GROSOR PERPENDICULAR A LA SUPERFICIE DE LA LAMINA DEL NUCLEO CON RESPECTO AL MENOS UNA UNIDAD DE SALIDA DE FIBRA OPTICA DESDE LA CUAL UN RAYO LASER SE PROYECTA SOBRE UNA SUPERFICIE EXTERIOR DEL CUERPO LAMINADO DE LAS LAMINAS DEL NUCLEO, EL RAYO LASER SE PROYECTA INTERMITENTEMENTE SOBRE EL CUERPO APILADO DE LAMINAS DE TAL FORMA QUE AL MENOS TRES LAMINAS SUCESIVAS DEL NUCLEO SE SUELDAN JUNTAS, Y ENTONCES EL CUERPO APILADO DE LAS LAMINAS DEL NUCLEO SE MUEVEN EN LA DIRECCION DE SU GROSOR EN UNA DISTANCIA SUBSTANCIALMENTE IGUAL A AL MENOS DOS VECES EL GROSOR DE LAS LAMINAS DEL NUCLEO. CUANDO SE DISPONE UNA PLURALIDAD DE UNIDADES DE SALIDA DE FIBRA OPTICA, DE TAL FORMA QUE ESTEN SEPARADAS EN UNA DIRECCION PERPENDICULAR A LA SUPERFICIE DE LA DIRECCION DEL GROSOR, SE PROYECTAN UNA PLURALIDAD DE RAYOS LASER SIMULTANEA O ALTERNATIVAMENTE CADA VEZ QUE EL CUERPO APILADO DE LAS LAMINAS QUE FORMAN EL NUCLEO SE MUEVE EN LA DIRECCION DEL GROSOR SOBRE UNA DISTANCIA SUBSTANCIALMENTE IGUAL A AL MENOS EL GROSOR DE LAS LAMINAS DEL NUCLEO. DE ESTA FORMA, DE ACUERDO CON LA INVENCION, ES POSIBLE OBTENER ZONAS SOLDADAS QUE ESTAN SEPARADAS EN LA DIRECCION DEL GROSOR Y/O EN LA DIRECCION DE LA SUPERFICIE.
