Abstract

L'objet de la présente invention est de fournir un mécanisme d'entraînement d'aimant capable d'amener un rotor à générer une force de rotation et capable de conférer une force de rotation prédéterminée au rotor en changeant la force d'entraînement d'armatures. Ce mécanisme d'entraînement d'aimant est caractérisé en ce qu'il est pourvu : d'un rotor (20), un groupe d'aimants permanents de pôle N et un groupe d'aimants permanents de pôle S étant fixés sur sa surface périphérique interne cylindrique au niveau de positions symétriques l'un par rapport à l'autre ; de multiples armatures (30) disposées à l'intérieur du rotor (20), de multiples aimants permanents de pôle N et de multiples aimants permanents de pôle S étant disposés sur les surfaces périphériques externes des armatures (30) dans la direction de l'axe central tandis que les multiples aimants permanents de pôle N et les multiples aimants permanents de pôle S sont agencés parallèlement les uns aux autres dans la direction circonférentielle externe ; et un moyen d'entraînement permettant de déplacer les armatures (30) dans une direction parallèle à l'axe central. Avant que des forces dirigées vers l'axe central de manière à agir sur les aimants permanents des armatures (30) ne viennent assurer un contrepoids, le moyen d'entraînement déplace les armatures (30) dans la direction parallèle à l'axe central afin de conférer une force de rotation au rotor (20).
