Each of the plurality of linear conductors includes a first straight portion extending out of the first molded resin portion in a direction parallel to a rotational axis of the rotor and connected to the terminal block, a second straight portion extending out of the first molded resin portion in a different direction from the first straight portion and a bent portion bent between the first and second straight portions. Of each of the plurality of linear conductors, a part of the first straight portion, the bend portion and a part of the second straight portion are covered by the first molded resin portion.

The invention relates to a method for repairing an electric generator, preferably in a wind turbine generator (WTG), the electric generator (10) having a stator and a rotor (30) rotatably mounted relative to the stator. The method of repairing the electric generator provides a rotor connecting ring (40) with a first conductor assembly and a second conductor assembly in two different planes, each assembly with a plurality of conductive arc segments. Each of the first and the second plurality of conductive arc segments form a ring-like shape in their respective plane, both ring-like shapes being concentrical to the central shaft (132) when the rotor connecting ring is mounted. First electrical connections (50) from the central shaft connect to the rotor connecting ring for the multiple phases (K,L,M). Second electrical connections (60) further connect from the rotor connecting ring to the respective windings of the multiple phases (K,L,M) on the exterior part of the rotor facing the stator. The rotor connecting ring enhances rotational and thermal stability of the electric generator.
