Abstract: In the connecting device for the electrical and mechanical connection of component conductors and for the supply or removal of the coolant to or from the hollow conductors (5) of the stator winding bars (3) of electrical machines, the hollow conductors (5) and, optionally, the solid conductors (4) of the winding bar in the winding head are held together in a metallic component (7). This component is connected to a water chamber (2) which is in turn provided with connecting fittings (6, 11) for the supply or removal of the coolant and is surrounded by an insulating jacket (10).Hitherto the production and assembly of said insulating jackets was very time-consuming. In order to shorten the assembly time, the insulating jacket comprises a preferably U-shaped insulating part (10) which is pushed over the metallic component (7), the water chamber (2) and the connecting fittings (6, 11) from the inside and overlaps the latter radially.

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.
