Abstract

LA PRESENTE INVENCION SE REFIERE A UN ELECTROIMAN DE ELEVACION QUE TIENE AL MENOS UN IMAN REVERSIBLE (5, 5'') MONTADO DE MANERA QUE SE ORIENTEN SUS POLARIDADES SEGUN UN EJE VERTICAL POR ENCIMA DE AL MENOS UN IMAN (6, 6'') PROVISTO DE AL MENOS UN PAR DE IMANES PERMANENTES (6A, 6A''). ESTOS IMANES PERMANENTES (6A, 6A'') ESTAN ACONDICIONADOS DE MANERA QUE SUS POLARIDADES ESTEN ORIENTADAS SEGUN UN EJE HORIZONTAL SOBRE LOS LADOS DE AL MENOS UN NUCLEO FERROMAGNETICO (6B, 6B'') ADECUADO AL CONTACTO CON LA CARGA (18) A ELEVAR. EL IMAN (6, 6'') ESTA TAMBIEN PROVISTO DE UN PRIMER DETECTOR ELECTROMAGNETICO (11) DISPUESTO CERCA DE LA BASE (6C, 6C'') DEL NUCLEO MAGNETICO CONSIDERADO Y DE OTRO DETECTOR ELECTROMAGNETICO (12) DISPUESTO POR ENCIMA DE LOS IMANES PERMANENTES (6A, 6A'') CONSIDERADOS DE MANERA QUE NO MIDAN PRACTICAMENTE MAS QUE EL FLUJO ELECTROMAGNETICO QUE ATRAVIESA EL IMAN REVERSIBLE (5, 5''). EL IMAN (6, 6'') ESTA, POR ULTIMO PROVISTO DE UN DISPOSITIVO DE SEGURIDAD (13) QUE PERMITE TRATAR LAS SEÑALESEMITIDAS POR LOS DETECTORES ELECTROMAGNETICOS (11, 12) Y OBTENER EL PUNTO DE FUNCIONAMIENTO DEL ELECTROIMAN DE ELEVACION EN LA CURVA DE MAGNETIZACION (14) DEL IMAN REVERSIBLE (5, 5'').
