ABSTRACT:
The device for holding the ends of the turns of a stator winding in a dynamoelectric machine comprises an inner ring (15) and a segmented outer ring (10). The stator winding, which consists of bottom and top bars (5, 6), is supported at the end side on the said outer ring (10), which in turn is supported by brackets (8) which are fastened to the machine end face. The bottom and top bars are spaced from one another by pressure hoses (13) filled with synthetic resin. The inner ring (15) consists of two rings having a closed inner conical ring (15b), an outer, preferably multipartite conical ring (15a) and support segments (15c), it being possible for the two conical rings to be braced axially with one another. A winding overhang support constructed in such a way fulfils all practical requirements and can also be reclamped subsequently.
