Zusammenfassung:An electrical generator (10) comprises a stator (20) having a stator body (21) extending axially between a first axial end (22) and a second axial end (23), the stator body (21) including a plurality of slots (30), the plurality of slots (30) being circumferentially distributed around a longitudinal axis (Y) of the stator body (21). The stator (20) includes a plurality of windings (17) housed in the plurality of slots (30) and a plurality of end-windings (18), each end winding having a curved shape and connecting the windings (17) in two slots (30) of said plurality of slots (30). The electrical generator (10) further comprises at least one air guide (51, 52) inside and/or outside the plurality of end-windings (18).
