Abstract
An electrical connection for an electrical machine having a slip ring bolt mounted with axial play in a radial shaft borehole and a suitable electrical connecting link between a slip ring and the slip ring bolt is provided, wherein the slip ring is mechanically disconnected from a rotor shaft. In one embodiment of the electrical connecting link, a contact carrier is rigidly connected with the slip ring bolt and which penetrates into an annulus formed in a slip ring on the side of the slip ring bolt. A contact lamination tape is placed into an annular slot formed in the contact carrier, which effects electrical connection between the contact carrier and the slip ring. In a second embodiment, a contact ring is provided at the end of the slip ring on the side of the slip ring bolt, which is connected with a slip ring bolt through a strap of copper-stranded wire.
