Abstract

L'invention concerne une machine dynamoélectrique à écart axial comprenant un disque de rotor disposé horizontalement et stabilisé en périphérie par plusieurs aimants permanents reliés à une plaque d'appui ferromagnétique qui produit une force d'opposition ou de répulsion contre les aimants du rotor. Dans certains modes de réalisation préférés, les aimants de la plaque d'appui sont disposés en deux bandes afin d'accroître le champ magnétique qui soutient la périphérie du rotor en rotation.
