Abrégé

The invention relates to a rotor (1) for an electric generator. The rotor comprises a cylindrical casing part (3) and a connecting structure arranged to mechanically connect the casing part (3) to a rotor shaft (5). The structure comprises at least one plane disc (4). The disc (4) is composed of a plurality of plane disc elements which comprise disc elements (7, 7a, 7b) that engage lockingly into each other in a puzzle- like manner. This means that where a first (7a) and a second (7b) disc element meet they have a complementary shape with at least one protrusion (8) on the first disc element (7a) and a corresponding number of recesses (9) of the same shape and a complementary position on the second disc element (7b). A protrusion (8) on the first disc element (7a) engages into a recess (9) in the other disc element (7b). At least one protrusion (8) has a varying width with a first portion closer to the outer end of the protrusion (8) that is broader than a second portion closer to the base part of the disc element. Hence a shape-permanent locking engagement is achieved so that a joint is formed between the first (7a) and the second (7b) disc element. The invention also relates to a method for manufacturing such a rotor.
