Abstract

The device for generating an electrical current, intended for a pipeline includes a pipe element (1), a rotor (2) suitable for being set in motion by the fluid and a stator (3a, 3b) arranged to cooperate with an end of the rotor (2) opposite to an axis of rotation (4) of said rotor (2) in order to generate the electrical current. The axis of rotation (4) is mounted at its opposing longitudinal ends (4a, 4b) on first and second supports (5a, 5b) arranged on either side of the plane of rotation (P1) of the rotor (2) and each linked to the pipe element (1). The stator has at least one ring (3a) arranged on one side of the rotor (2), and each ring (3a, 3b) includes a circuit suitable for generating all or part of the electrical current when excited by a magnetic element of the rotor (2).
