摘要： It is described an electric generator for a wind turbine, which comprises a stator (2), a rotor (3) and a plurality of stator gaps (6) between axially adjacent segments (7) of said stator (2). At least one stator gap (6) is inclined compared to a radial direction of said generator with respect to an axial longitudinal section and said inclinations between the stator gaps (6) and said radial direction of the generator vary in axial direction. Alternatively or in addition, a width (w1, w2) of the stator gaps (6) between axially adjacent segments (7) of said stator (2) vary in axial direction. Moreover, an electric generator arrangement (1) comprising an electric generator and a fan (4) is disclosed.

摘要： It is described a pole shoe arrangement (100) for a rotor (400) of a generator. The generator comprises a stator and the rotor rotatable around the stator. The pole shoe arrangement comprises a first pole shoe element (101) being made of ferromagnetic material, and a second pole shoe element (102) being made of ferromagnetic material. The first pole shoe element (101) and the second pole shoe element (102) are attached to a rotor support structure. The first pole shoe element (101) and the second pole shoe element (102) extend in an axial direction of the rotor and are spaced in relation to each other in a circumferential direction of the rotor in such a manner that a recess is formed for receiving a magnet assembly (103). Each pole shoe element has a first width in the circumferential direction at a first radial inner position and has a second width in the circumferential direction at a second radial outer position, wherein, in the radial direction, the first width transitions to the second width in a stepwise manner, wherein the second width is smaller than the first width It is further described a rotor and a generator.
