Abstract

[Problème] Fournir une unité de mouvement qui est capable d'assurer une force de répulsion tandis qu'un moyen de génération de force magnétique est réduit en taille. À cet effet, des aimants côté mouvement 24A, 24B et des aimants côté fixe 6A, 6B sont séparés magnétiquement, et les directions des pôles magnétiques des segments adjacents sont opposées l'une à l'autre, de sorte que des lignes de champ magnétique puissent être convergentes sur des surfaces d'extrémité des aimants. Même lorsque les aimants sont réduits en taille, les forces de répulsion entre les aimants côté mouvement 24A, 24B et les aimants côté fixe 6A, 6B peuvent être assurées.
