Abstract
UN COJINETE MAGNETICO AXIAL POLARIZADO POR CORRIENTE CONTINUA INCLUYE UN MIEMBRO GIRATORIO (50) (O EJE) QUE TIENE UNA PROYECCION (O SOPORTE) (52) SITUADA ENTRE UN PAR DE DIENTES (62, 64) DE UN MIEMBRO DE CONTROL EN FORMA DE C (60). UN IMAN PERMANENTE (68) SUMINISTRA UN CAMPO MAGNETICO DE CORRIENTE CONTINUA (82) QUE SE MUEVE A TRAVES DE UN BRAZO SALIENTE (70) Y SUMINISTRA UNA FUERZA DE ATRACCION DE POLARIZACION DE CORRIENTE CONTINUA ENTRE UNA SUPERFICIE (72) DEL BRAZO (70) Y UNA SUPERFICIE SUPERIOR (74) DEL EJE (50) QUE HACE LEVITAR EL EJE (50) DE MANERA QUE LA PROYECCION (52) ESTE SEPARADA IGUALMENTE ENTRE LAS SUPERFICIES (62, 64). LAS BOBINAS ESTAN ENROLLADAS CIRCUNFERENCIALMENTE ALREDEDOR DEL EJE (50) DENTRO DEL MIEMBRO DE CONTROL EN FORMA DE C (60) Y LA CORRIENTE A TRAVES DE LAS BOBINAS SUMINISTRA UN CONTROL FINO ELECTROMAGNETICO DE LA POSICION DE LA PROYECCION (52) ENTRE LAS SUPERFICIES (62, 64) EN RESPUESTA A LOS CAMBIOS EN LA POSICION AXIAL DEL EJE (50) INDICADOS POR LOS SENSORES DE POSICION (96). EL COJINETE TAMBIEN UTILIZARSE EN APLICACIONES HORIZONTALES, POR EJEMPLO EN UN MOTOR
