<p>The invention is a hydroelectric power generator (1) interposed in a duct, comprising: an external casing (2) in which it is possible to identify an inlet pipe fitting (3) and an outlet pipe fitting (4) for the fluid; an impeller (5) arranged inside the casing (2) so that the fluid entering through the inlet pipe fitting (3) intercepts a plurality of blades (51) defined on a first surface (52) of the impeller (5), setting the impeller rotating around a rotation axis (X); magnetic means (6) fixedly coupled with the impeller (5) and suited to interact electromagnetically with a stator (7) integrated in the casing (2) so as to generate electric energy when the impeller (5) is set rotating around the rotation axis (X). In the generator (1), the body of the impeller (5) comprises a seat (53) with substantially longitudinal development on the opposite side of the impeller with respect to the blades (51), so that the seat (53) can be coaxially and freely coupled with a pin (8) integral with the casing (2) and projecting from the latter along the rotation axis (X).</p> |
