| description | The present disclosure relates to a method for manufacturing the windings of an rotating electric generator. Joining copper half coils (1,2) to a winding of such a generator rotor is usually accomplished by a brazing process, wherein each single conductor to be joined is heated on its own to the brazing temperature after the brazing material is carefully positioned in the joint area, located at the half coil end portions. This conventional method requires a long time for an entire rotor, which results in high production costs. The object of the present invention is to provide a method for joining of conductors of rotating electrical machines which is faster and reduces negative effects of the heating, which is impacting adjacent portions, to a minimum. This object is realised by means of a brazing element (4) which is positioned over the ends of half coil stacks (1A,2A) to be joined. |
