ABSTRACT:
An amortisseur bar interconnection arrangement for a synchronous dynamoelectric machine rotor in which amortisseur bars embedded in the various rotor poles are interconnected by a pair of segmented conductive strips disposed about the circumference of the rotor hub. The amortisseur bars for each pole are supported by a pair of conductive rotor pole end laminations. When the rotor poles are attached to the rotor hub, the end laminations each physically engage a segmented conductive strip disposed in an annular recess formed on the circumference of the rotor hub, thereby completing the electrical connection between the various amortisseur bars. The segmented conductive strips are backed by a compressible resilient pad which maintains sufficient engagement force between the end laminations and the conductive strip to ensure a solid electrical connection therebetween.
