Abstract

A segment sheet for a stator lamination stack of a generator of a wind turbine, wherein the segment sheet has the shape of a ring segment, having a first radial section, in which recesses are provided for receiving a stator winding, having a second radial section, which is arranged radially adjacent to the first section and which forms a segment of a magnetic yoke of the generator, and having a third radial section, which is arranged radially adjacent to the second section. The proposal is that the third radial section has at least two recesses arranged in an azimuthally spaced manner, which are designed for a positive connection to profiled strips arranged on a stator support ring.
