  • the magnets arranged face to face, for example, their South poles each directed towards one of the branches of the armature and their North poles directed towards the nucleus. So the quasi-closed magnetic core comprises the core, the armature, the magnets and the air gap arranged in series.
  • the nucleus When the mechanical action on the nucleus ceases, the nucleus is attracted to its initial position by the magnetic field produced by the permanent magnets. So the magnets permanent have two functions.
  • a first function of the magnets is to generate an intense magnetic flux when the magnetic circuit is closed or almost closed, the core being in contact with the armature. At when the core is separated from the armature, the magnetic flux drops suddenly thus producing the flux variation which excites the coil to generate energy electric.
  • a second function of permanent magnets is to return the core to its position initial, in contact with the reinforcement. To ensure this function, the nucleus is limited in its displacement. The distance between the core and the armature of the magnetic circuit is less than the maximum distance which allows an effective recall of the nucleus.

Between the two positions a distance L is less than the maximum recall distance of the core preferably this distance is less than 4 mm.
  • Figures 6 and 7 respectively show a side view and a sectional front view of a particular embodiment of the generator assembly 23 of FIG. 4.
