Abstract

Générateur (100) dans lequel l'intensité de magnétisme H (AT/m) émis par les faces polaires du pôle N d'un aimant permanent (10) et du pôle N d'un aimant permanent (11) est introduite dans une seconde culasse (20N) et, sur le côté opposé également, les faces polaires du pôle S de l'aimant permanent (10) et du pôle S d'un aimant permanent (12) sont disposées l'une en face de l'autre, ce qui permet de former une boucle de circulation pour la circulation vers une première culasse (20S). L'intensité de magnétisme H (AT/m) émis par les deux faces polaires de l'aimant permanent (10) est aspirée dans la seconde culasse (20N) et la première culasse (20S), et de l'énergie électrique est générée dans la boucle de circulation de l'intensité de magnétisme H (AT/m) par un phénomène d'induction électromagnétique entre l'intensité de magnétisme H (AT/m) et une génération d'énergie d'enroulement secondaire (60), un noyau d'armature magnétique (40) étant disposé dans la boucle de circulation parmi une fuite de flux magnétique (intensité de magnétisme H [AT/m]) entre les première et seconde culasses. Un circuit électronique permet de réaliser ce qui précède.
