Abstract: Electrical machine, e.g., a generator, having a stator comprising a winding overhang, a rotor arranged rotatable in the stator, and a heat exchanger fluidically connected to the winding overhang via a coolant shaft, which is arranged radially outside the winding overhang, runs at least partially approximately along a circumferential direction, and is delimited in a radial direction by an outer surface, so that the winding overhang can be cooled by a continuous flow of a fluid over the heat exchanger and the winding overhang. To obtain uniform cooling of the winding overhang, multiple guiding elements are arranged in a distributed manner along a circumferential direction in the coolant shaft to redirect a flow of a fluid oriented in a circumferential direction in the coolant shaft at least partially into a radial flow towards the winding overhang and to distribute the flow to multiple regions of the winding overhang.
