Abstract: An electrical machine includes a first active part and a second active part. Both the first active part and the second active part have a plurality of laminated sub-cores, with each laminated sub-core having a plurality of individual laminations. Each lamination is defined by an axial width. The laminated sub-cores are mutually spaced in an axial direction such that a respective radial cooling slot is formed between two adjacent laminated sub-cores. The radial cooling slots in the first active part are offset in the axial direction in relation to one another in comparison to the radial cooling slots in the second active part, and the sum of the axial widths of all individual laminations in the first active part corresponds to the sum of the axial widths of all individual laminations in the second active part.

Abstract: A slip ring bridge, in particular for use in a wind power installation, includes at least two segments configured to provide electrical power, and an insulation element configured to insulate the segments to maintain the segments in spaced-apart relationship. The insulation element includes a shield arranged inside the insulation element and connected to a constant electric potential.

Abstract: A slip ring unit for an electrical machine is provided for accommodating a carbon brush system. The slip ring unit includes at least one insulating segment having shaped sections for cooling parts of the electrical machine. The insulating segment having the shaped sections is shaped from the insulating segment as a fanwheel, wherein the insulating segment having the shaped sections forms a fan to distribute a cooling air flow to the parts of the electrical machine to be cooled. The slip ring unit has boreholes on the sides of supports of the slip rings for passage of cooling air.

Abstract: A slip ring unit for an electrically excited rotor of a rotary dynamo-electric machine includes an electrical terminal which protrudes axially from an end face of the slip ring unit and having a contact point and a circumferential slip contact surface electrically connected to the electrical terminal. Disposed adjacent to the slip contact surface is an insulation element, with end plates axially retaining the circumferential slip contact surface and the insulation element. An electrically insulated support element is arranged on an end face of the slip ring unit and has a cross section which substantially matches a cross section of the slip ring unit. The support element axially surrounds the electrical terminal and radially supports the electrical terminal.
