Abstract

L'invention concerne un rotor discoïde (10') pour une machine électrique à flux axial comprenant une pluralité de pôles d'aimants (12') disposés sur la partie périphérique dudit rotor autour d'un élément d'arbre (14') destiné à entraîner un arbre en rotation, les pôles d'aimant étant intégrés à un support en matériau composite (16'), le rotor comprenant en outre une frette cylindrique (18') disposée en partie périphérique dudit rotor pour entourer les pôles d'aimant (12'), caractérisé en ce que la frette cylindrique (18') est agencée de sorte à exercer un effort de précontrainte sur les pôles d'aimant (12') sous-jacents , apte à comprimer les pôles d'aimant (12') sous-jacents en direction de l'élément d'arbre (14') par l'intermédiaire d'inserts (19') disposés radialement entre les pôles d'aimants (12') et l'élément d'arbre (14').
