  • Patent number: 6984912
    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).

  • Patent number: 6965187
    Abstract: In the case of a rotor (10) having a rotor spider (11), which is mounted such as it can rotate about an axis (15) and has two or more ribs (12), and having a laminated rim (14), which concentrically surrounds the rotor spider (11) and is composed of individual rim laminates (16), and which is connected to the rotor spider (11) by means of wedges (13) via a laminated rim wedge system, a simplified connection between the laminated rim (14) and the rotor spider (11) is achieved in that the wedges (13) and the rim laminates (16) are designed such that they engage in one another in an interlocking manner, forming a rigid connection.
