Abstract

L'invention concerne un dispositif de génération d'électricité constitué d'une structure selon laquelle un rotor principal tourne à l'intérieur d'un stator. Le dispositif comporte le rotor principal (44), des premières unités d'aimants permanents (51) et des secondes unités d'aimants permanents (52), les premières et secondes unités d'aimants permanents étant installées à des intervalles égaux sur la périphérie extérieure du rotor principal. Les pôles magnétiques aux bouts de chacune des premières unités d'aimants permanents (51) et de chacune des secondes unités d'aimants permanents (52) présentent des polarités opposées les unes aux autres. Les premières et secondes unités d'aimants permanents (51, 52) comportent chacune un corps magnétique (12) possédant des pôles magnétiques aux deux extrémités dans le sens de l'épaisseur du corps magnétique, un élément en forme de voûte (30) comportant deux pentes s'étendant obliquement à partir d'une section de nervure et formé à partir d'un matériau paramagnétique, ainsi qu'un moyen de raccord (20) permettant de raccorder en une seule pièce ces éléments. Les noyaux (53) du stator sont disposés de manière fixe autour des premières et secondes unités d'aimants permanents (51, 52) et des fils de bobinage (54) sont enroulés autour des noyaux.
