Definitions

  • the piles of one set are arranged to extend in parallel with the piles of the other set, and said core has a H-like shape as seen in the direction of extension of said piles with the web of said H formed by a said first core section provided with said winding separating the piles of the two sets from each other and the legs of the H have the two ends connecting to one set of piles each .
  • the H-shape makes the generator with core and piles symmetric and the winding may be applied around one core section being in common to two parallel magnetic circuits.
  • Fig 10 is a simplified perspective view of a part of a generator according to a third embodiment of the invention .
  • a generator according to a first embodiment of the invention is schematically and very simplifiedly illustrated in a perspective view in Fig 1 . It is shown how the generator 1 is connected to a buoy 2 located at the surface of a sea 3 for being moved by sea waves and by that also move a movable part of the generator for generating electric energy from the kinetic energy of the buoy 2.
  • the general construction of the generator shown in Fig 1 will be explained while at the same time also making reference to Figs 2-4.
  • the generator has two first piles 4, 5 of a plurality of permanent magnets 6 with magnetization in the direction in extension of the pile. Adjacent magnets are separated by a first member 7 of magnetically permeable material and have opposite magneti- zation direction .
  • Figs 3 and 4 How the magnetic flux through the cores is brought to be varying with time is schematically illustrated through Figs 3 and 4. It is shown how the magnetic flux from the permanent magnets will find a way through the first members of these piles and the second members of the second piles and further in said closed loop through the core in one direction when the second piles have a position shown in Fig 3 with respect to the magnet piles 4, 5 and how the magnetic flux direction has changed to be the opposite when the second piles have been moved from the position shown in Fig 3 to the position shown in Fig 4.
  • the magnet piles may be called "flux concentrators" by having the magnets directed towards each other with a said first member 7 therebetween .
  • the total length I of the electric conductor 21 of each winding 23 is much shorter than in conventional generators of this type per unit induced voltage and will by that have a much lower winding resistance.

Abstract

La présente invention concerne un générateur permettant de générer de l'énergie électrique à partir de l'énergie cinétique du déplacement de l'eau de mer et comprenant au moins une première pile (4, 5) d'une pluralité d'aimants permanents (6) séparés par un premier élément (7) de matériau magnétiquement perméable, deux secondes piles (8-10) de seconds éléments (11) de matériau magnétiquement perméable s'étendant le long de deux côtés différents de la pile d'aimants, un noyau (17-19) de matériau magnétiquement perméable formant une boucle fermée d'une seconde pile à l'autre pour permettre à un flux magnétique de passer de la pile d'aimants à une seconde pile et de revenir à travers le noyau, et un enroulement (23) d'un conducteur électrique (21) autour d'une section (20) du noyau. La pile d'aimants et les secondes piles peuvent se déplacer les unes par rapport aux autres pour générer un flux magnétique variable dans le temps dans le noyau de manière transversale à la direction de ce déplacement.
