ABSTRACT:
The invention relates to a winding arrangement for an electric machine with a polyphase winding, in which a plurality of coils or coil groups connected in parallel (50, 52, 54, 56) are connected with a conductor rail (40, 42, 44, 46). This makes it possible to connect the coil ends directly and without connecting pieces with the electric power supply. The conductor rails (40, 42, 44, 46) are preferably arranged at one or both face sides of the post of the electric machine below the slot openings, i.e., in the area of the back of the post.Furthermore, the invention is aimed at an corresponding manufacturing method for a winding arrangement of a polyphase winding for an electric machine, in which the coils or coil groups connected in parallel (50, 52, 54, 56) of the winding are connected with one of the conductor rails (40, 42, 44, 46).
