Abstract:
An electric power generator, comprising:an internal moving contact inside a non-magnetic section of a pipe in which a fluid circulates, including,at least one permanent magnet,a mechanical drive power element coupled to the permanent magnet and acted upon by the circulating fluid to produce a rotation of the permanent magnet in response to circulation of the fluid,and at least one bearing supporting said permanent magnet and the mechanical drive power element in the pipe; anda stator placed around the section of the pipe, including,a permanent magnetic circuit having at least one induction coil,wherein the stator is offset longitudinally with respect to the permanent magnet of the internal moving contact, comprising:an external moving contact placed between the pipe and the stator, at least made partially of a ferromagnetic material, and positioned longitudinally with respect to the stator, including,at least one external permanent magnet on an outer periphery of the external moving contact, andat least one internal permanent magnet on an inner periphery of the external moving contact and positioned longitudinally with respect to the permanent magnet of the internal moving contact,wherein the external moving contact is driven magnetically in rotation by the internal moving contact.
