Abstract (en)
[origin: WO2020094884A1] The invention relates to a segment sheet (21, 47, 53, 55, 65, 93) for a stator lamination stack (15) of a generator (1) of a wind turbine (100). The segment sheet (21) has the shape of a ring segment with a first radial section (23) in which recesses (29) are provided for receiving a stator winding, a second radial section (25) which is arranged adjacently to the first section (23) in the radial direction and which forms a segment of a magnetic yoke of the generator (1), and a third radial section (27) which is arranged adjacently to the second section (25) in the radial direction. According to the invention, the third radial section (27) has at least two recesses (36, 49, 59, 61, 71) that are arranged in an azimuthally spaced manner and are designed to connect to profiled strips (13, 41, 51, 67, 97, 107), which are arranged on a stator support ring (7), in order to establish a form-fitting connection.
