Abstract: The present invention relates to a cover cap for a connection of two electrically conductive interconnected ends of two winding bars of a stator of an electric machine. The cover cap includes an electrically insulating housing that surrounds and seals a circumference of the connection when mounted. The cover cap has a spring device disposed in an interior of the housing and configured to be clipped onto the connection so as to mount the housing and is supported on the connection on said housing when the housing is mounted so as to provide a force for fixing the housing to the connection.

Abstract: An electrical machine comprises a stator (10) with a laminated core (11) in which two or more slots (12) are provided which run in the axial direction and in each of which two or more winding bars (13, 14) are arranged one above the other in the radial direction and are separated from one another by spacers (19) between them, and in which channels (20) which run parallel to the winding bars (13, 14) are provided, through which a cooling medium flows, in order to cool the winding bars (13, 14) and, considerably better cooling of the winding is achieved with little complexity in that tubular facing elements (19), which extend in the axial direction and whose interior in each case forms a channel (20) for the cooling medium are used as spacers.

Abstract: A dynamoelectrical machine (20) has winding bars (13) which are inserted into slots provided for this purpose in the dynamoelectrical machine (20), with the slots each being closed by cover wedges (23), and with corrugated springs (16) being provided between the cover wedges (23) and the winding bars (13) located underneath them, which are prestressed by means of opposing wedges (21), which are arranged between the cover wedges (23) and the winding bars (13) located underneath them. In a machine such as this, fast and simple wedging is made possible in that the opposing wedges (21) are arranged between the cover wedges (23) and the corrugated springs (16), and in that fixed-position adjusting elements (22) are provided, by means of which it is possible to vary the distance between the cover wedges (23) and the opposing wedges (21).
