Abstract

La présente invention concerne un ensemble (17) pour compresseur de turbomachine d’aéronef dans lequel un aimant d’aube (58) est situé sur une aube rotorique aimantée (56) et une première virole (34) comprend un aimant de virole (70). Lorsque la distance (72) entre l’aimant d’aube (58) et l’aimant de virole (70) est inférieure à un seuil, l’aimant d’aube (58) repousse l’aimant de virole (70) de façon à faire passer la première virole (34) d’une position radialement interne (64) à une position radialement externe (66).
