An electric machine includes a hollow-cylindrical stator and at least two receiving elements, each receiving element at least partially enclosing the stator in a circumferential direction along an inner coverage length and conjointly connected to the stator in the circumferential direction along an inner fastening length. A stator housing is conjointly connected to the receiving elements in the circumferential direction along the outer fastening length. The inner fastening length extends at most along 120° in the circumferential direction, and the outer fastening length extends at most along 200° in the circumferential direction.

Electric machine and wind turbine

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.

An electrical machine with a stator has a winding support, which has at least one radial cooling slot, and a rotor, which likewise has at least one radial cooling slot. The winding support of the stator has on its outer shell a number of axially running cooling ribs, along which an axially running first cooling flow can be directed. Furthermore, the rotor has axially running first cooling ducts, which open out into its at least one radial cooling slot, so that a second cooling flow can be directed in the axial direction along the axial cooling ribs of the stator through the axial first cooling ducts of the rotor, the at least one radial cooling slot of the rotor, the air gap between the rotor and the stator and the at least one radial cooling slot. In this way, the stator can be cooled by two different cooling flows.
