Abstract

La présente invention concerne une éolienne à suspension magnétique qui a un arbre vertical, un corps d'éolienne et un générateur. Le corps d'éolienne est monté sur une bride porteuse. Le générateur comprend un boîtier (1), l'arbre vertical (2), un palier (3), un rotor à magnétisme permanent, un noyau de stator en forme de disque (7) et un enroulement. Le boîtier (1) est formé par des plaques d'appui supérieure et inférieure (11, 12), et une plaque circonférentielle (13) qui se situe entre les plaques d'appui supérieure et inférieure. L'extrémité supérieure du noyau de stator en forme de disque (7) est fixée sur la plaque d'appui supérieure (11). L'acier magnétique (5) du rotor à magnétisme permanent est opposé à l'extrémité inférieure du noyau du stator en forme de disque (7) et un dégagement est prévu entre eux. Avec la structure ci-dessus, en utilisant l'attraction entre le noyau du stator en forme de disque (7) et l'acier magnétique (5) du rotor à magnétisme permanent, la force axiale du palier peut être surmontée, l'abrasion du palier peut être réduite et la durée de vie du palier peut être prolongée. Dans le même temps, la force de friction du palier peut être réduite et l'efficacité mécanique peut être améliorée.
