Abstract

L'invention porte sur une génératrice magnétique à couples égaux, qui comprend un stator, un rotor, des cols magnétiques, des gaines magnétiques et une carcasse. Chaque enroulement sur le stator est composé de deux groupes de bobines reliés en série. Chaque enroulement est fixé autour d'un col magnétique. Le col magnétique est relié de façon fixe à la gaine magnétique pour former un tout. Chaque groupe de bobines est composé d'une bobine A et d'une bobine B. La bobine A est reliée à un condensateur en série et la bobine B sert à la sortie. Pendant que la génératrice travaille, le rotor tourne. Dans le processus dans lequel l'aimant se rapproche, en correspondant entièrement à, et en s'éloignant de, l'enroulement correspondant et la gaine magnétique, les effets magnétiques des aimants sur le rotor et des enroulements de stator sont égaux entre eux et symétriques, les résultats de force magnétique sont pour la plupart compensés, le couple de résistance de rotation du rotor est réduit, le couple d'entraînement nécessaire pour la rotation du rotor diminue et le condensateur série augmente l'effet d'excitation de la génératrice, avec pour résultat que la génératrice fournit de l'énergie avec un haut rendement. L'invention a une structure simple, un haut rendement de conversion d'énergie et peut être largement utilisée dans des équipements de production d'énergie tels qu'une centrale électrique.
