Dynamoelectric machine comprising wedged winding bars

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 ).
