Abstract
Perfeccionamientos en dispositivos de amortiguación de las frecuencias críticas de un rotor suspendido magnéticamente, por medio de una suspensión magnética que comprende al menos un cojinete magnético radial provisto de arrollamientos de electroimanes, al menos un dispositivo de detección radial de la posición axial del rotor, y un circuito de subordinación conectado al dispositivo de detección y a los arrollamientos y que comprende un circuito de control de alimentación de estos arrollamientos que actúa como respuesta a unas señales proporcionadas por los dispositivos de detección para mantener el rotor en una posición axial predeterminada, caracterizados porque el circuito de subordinación comprende medios de amplificación selectiva de la ganancia en fase o en avance de fase de este circuito en una banda de frecuencia centrada sobre una frecuencia igual a la velocidad de rotación del rotor expresada en vueltas por segundo.
