Abstract: A dynamoelectric machine includes a shaft, a rotor arranged fixedly on the shaft for conjoint rotation, and a slip ring system enabling a rotor winding system to be contacted electrically and including a slip ring body having slip rings arranged spaced-apart axially behind one another and assigned to an electrical phase. The slip ring body is connected fixedly to the shaft for conjoint rotation and has between an inner side thereof and the shaft a section which forms an axially open cavity on both skies. In a region of the slip ring system, the shaft is hollow with a hollow shaft portion assigned to the slip ring system for routing feed lines to the rotor winding system. Recesses are provided on the cavity axially on an inside and axially on an outside for introducing a cooling medium flow axially into the cavity and discharge thereof into an outlet region.

Abstract: A tooth-wound coil of a stator or of a stator segment of a dynamo-electric machine having two straight sections spaced apart from each other and running substantially parallel. Two 180° curves are located on the ends thereof, wherein the straight sections have an active part area, the axial extend of which is less than or equal to that of the straight section. The tooth-wound coil has a symmetrical extension plane running in the longitudinal direction. An insulation material is provided around the straight sections of the tooth-wound coil. The material effects groove isolation and/or phase isolation in the stator or stator segment.

Abstract: A coupling includes a claw part and an intermediate piece. The intermediate piece includes a tube piece produced from aluminum or from an aluminum alloy, and a buffer part received in an end region of the tube piece and including elastic damping elements for receiving the claw part. The damping elements are surrounded by the end region radially at an outside in a circumferential direction. The buffer part includes a part which is different from the damping elements and is produced from a material of a brittleness which is greater than a brittleness of the tube piece.

Abstract: A wind turbine includes a dynamoelectric machine including a liquid-cooled stator and a rotor interacting with one another. The stator includes a magnetically conductive body and a winding system which is embedded in slots of the magnetically conductive body and which includes a main insulation arranged between a conductor of the winding system and a slot wall and including at least one recess provided in a cooling-channel impression of the main insulation to form at least one axial cooling channel extending between the main insulation and the slot wall, so that the at least one cooling channel borders the slot wall without insulation in direct contact with the slot wall. The winding system includes end windings which are also liquid-cooled. A can separates the stator and the rotor from one another and enables different cooling media for the stator and the rotor.

Abstract: A plain bearing bush includes a cylindrical main body having a first shell surface and a second shell surface. The first and second shell surfaces include a plurality of exchange bores for a lubricant. At least one of the exchange bores has a first diameter on the first shell surface and a second diameter on the second shell surface, with the second diameter being greater than the first diameter for an increase in a load-bearing capability of the plain bearing bush. Two of the exchange bores are arranged in axial spaced-apart relation and connected to one another by a pocket depression.
