La présente invention concerne un générateur de rotation destiné à générer de l'électricité à partir de l'énergie de rotation d'un véhicule en mouvement, le générateur de rotation comprend un rotor qui est défini par une pluralité d'aimants qui peuvent être fixés à une jante de telle sorte que la pluralité d'aimants se mettent en rotation en même temps que la jante. Le générateur de rotation comprend également un stator sous la forme d'un disque annulaire qui peut être fixé à un moyeu de roue. Le stator est façonné et dimensionné pour s'insérer à l'intérieur de la jante et comprend une pluralité d'enroulements de bobine qui s'étendent radialement vers l'extérieur vers la périphérie du disque annulaire. Lors de l'utilisation, lorsque le générateur de rotation est installé sur un véhicule, la pluralité d'aimants se mettent en rotation conjointement à la rotation de la roue tandis que le stator est retenu dans une position stationnaire, induisant ainsi un courant électrique dans les enroulements de bobine.
