Zusammenfassung:	A slot wedge of a dynamoelectric machine which includes a stator having axially extending slots and a winding system disposed in the slots, is configured to cover a corresponding one of the slots in a direction of an air gap and includes a first layer, and a second layer arranged in spaced-apart to the first layer at least in one section to form a flow channel between the first and second layers. The second layer can have a perforation with a different density of holes per unit area, with the density of the holes being greater in a central area of the second layer and/or a perforation having holes defined by a diameter which is greater in a central area of the slot.
