Abstract: L'invention concerne une machine électrique consistant en une forme de base constructive lui permettant de servir de moteur et de générateur, et de fournir un rendement élevé de la bobine sans support, sur l'espace le plus réduit, pour des mouvements rotatifs et linéaires. Il s'agit dans le cas de cette forme de base constructive, d'une bobine sans support (3) à laquelle appartiennent deux faces de bobine qui, au moment où la conversion d'énergie est maximale, sont à l'opposé de pôles (27) magnétiques opposés et dont l'action est alors complémentaire. La bobine sans support n'a pas de contact avec le matériau de reflux et se trouve de manière approximativement centrée dans un entrefer (4) formé par un dispositif de champ (6, 7) ou dans un entrefer (4) consistant en une ou en plusieurs sections d'entrefer (4', 4''...) et se déplace par rapport auxdites sections. Chaque face de la bobine traverse les sections de l'entrefer (4',4''...), sa forme géométrique se modifie en coupe transversalement au sens du mouvement et est cintrée ou pliée autour d'au moins un corps (6) du dispositif de champ et se trouve dans l'ensemble sensiblement dans l'entrefer (4). Cette structure d'entrefer et des bobines sans support qui s'y trouvent permet de satisfaire de manière optimale aux conditions idéales exposées par M. Faraday en termes de conversion d'énergie lors du mouvement relatif entre le conducteur électrique et le champ magnétique et garantit un rendement optimal du cuivre au plan quantitatif et qualitatif dans lesdites bobines sans support. L'invention permet également de produire des machines très compactes, ce qui induit une pluralité d'autres avantages en termes d'application, de fabrication et de coûts de production. Ces machines et le haut rendement qu'elles permettent d'atteindre, s'utilisent par ex. comme moteurs pour des opérations d'ajustement extrêmement rapides ou comme mécanismes d'entraînement pour des véhicules et comme générateurs pour des dynamos d'éclairage de véhicules ou pour des installations d'énergie éolienne.
