Abstract
An energy recovery device including at least one first magnet, able to be set in movement according to a rotational or translational movement; a main magnet, able to be set in rotation about an axis by said at least first magnet; at least one second magnet, fixedly disposed with respect to the main magnet, for determining one or more positions of equilibrium of the latter; at least one conductive coil for transforming a variation of orientation of the main magnet into electrical energy, wherein in a 1st speed or frequency range a coupling of said at least one first magnet and of said main magnet causes the rotation of the latter from at least one position of equilibrium, the oscillations of said main magnet around said at least one position of equilibrium resulting in the creation of an electrical energy in said at least one conductive coil; and for a 2nd speed or frequency range a coupling of said at least one first magnet and of said main magnet causes the rotation of the latter, without oscillations, and this rotation results in the creation of an electrical energy in the coil.
