Abstract

La présente invention concerne un générateur électrique possédant un induit placé à l'intérieur d'un champ magnétique coaxial. À la fois l'induit et le champ magnétique possède une première extrémité axiale montée sur un arbre d'entraînement et une seconde extrémité axiale qui est libre. Les arbres d'entraînement respectifs sont situés à des extrémités axiales opposées du générateur, et sont agencés pour tourner en sens inverse de telle sorte que la rotation des arbres d'entraînement entraîne une rotation relative directe de l'induit et du champ magnétique.
