METHOD FOR PRODUCING A MAGNETICALLY EXCITABLE CORE COMPRISING A CORE WINDING FOR AN ELECTRIC MACHINE

摘要

The invention relates to a method for producing an electromagnetically excitable core for an electric machine. According to said method, in a first step (S1) a core (24) having a substantially parallelepipedal shape (20) with grooves (32) on one side which run parallel to each other, is provided. In a second method step (S2), a core winding (40) comprising its winding faces (36) is inserted into said grooves (32) and in a third method step (S3), the core (24) together with the core winding (40) is formed in an annular cylindrical mould (52) with grooves (32) which extend radially towards the interior. The method is characterised by an additional step, in which all the winding faces (36) that are respectively inserted into one groove (32) are pressed and formed in a groove mould (119) in a tool (44), before insertion into the groove (32). The invention also relates to a stator (150) produced according to said method and to an electric machine (140) comprising said stator (150).
