Abstract

PARA UN ROTOR SE PRESENTA UN SOPORTE MAGNETICO CON IMANES PERMANENTES PARA TOMA DE LAS FUERZAS DE COJINETE RADIALES Y CON UN ESTABILIZADOR QUE SUJETA EL ROTOR EN UNA SITUACION SIN CONTACTO EN EL ESTATOR. EN EL ESTATOR SE INTRODUCEN BOBINAS ELECTRICAS QUE ACTUAN CONJUNTAMENTE CON LAS PARTES MAGNETIZABLES FIJAS EN EL ROTOR. PARA HACER EL SOPORTE INDEPENDIENTE DE LA ORIENTACION ESPACIAL DEL JEJE DEL ROTOR ASI COMO DE LAS DEFORMACIONES DEL DEPOSITO, SE COLOCA EN LA ZONA DEL PUNTO DE DIFICULTAD (5) CON ELEVADA RIGIDEZ RADIAL Y EN LA OTRA POSICION DEL ROTOR 1 UN COJINETE DE ESTABILIZACION (7) CON PEQUEÑA RIGIDEZ RADIAL EN COMPARACION CON EL COJINETE DE PUNTO DE DIFICULTAD. EL COJINETE DE PUNTO DE DIFICULTAD (5) LLEVA EN LA MAYOR PARTE DEL PESO DEL ROTOR, QUE RECIBE EL COJINETE DE ESTABILIZACION (7) EN LA ESTABILIZACION ESTATICA Y DINAMICA DEL SISTEMA TOTAL.
