Abstract:
1. An electric power-generating device comprising: a first main portion made of a ferromagnetic material forming at least one magnetic circuit comprising a core and at least one pair of branches magnetically coupled to the core supporting closure ends of the at least one magnetic circuit, a second main portion comprising at least one permanent magnet placed to close the magnetic circuit by relative movement of the first main portion relative to the second main portion, the at least one permanent magnet being polarized in order to have a magnetic flux flow in the magnetic circuit when the magnetic circuit is closed, a mechanism for movement by rotation of a movable portion consisting essentially of one or other of the main portions about an axis of rotation supporting the core in order to close the at least one magnetic circuit, and an electric coil wound around the core in order to gather the electric power obtained while the movable portion rotates, wherein the movement mechanism comprises control means and priming and driving means coupled to the control means in order to establish a priming of the mechanism by accumulating a priming power generated by at least one portion of the travel of the control means, the priming and driving means interacting with the movable portion in order to drive it between two stable positions while releasing the priming power at the end of travel of the control means.
