An electric machine has a stator and a rotor arranged on a hollow shaft and able to turn relative to the stator about an axis of rotation, wherein the hollow shaft comprises, in a shaft casing, at least one shaft exit opening for coolant supplied to a shaft interior space of the hollow shaft. A cover element is arranged next to the rotor on the hollow shaft, in which is formed a fluid duct comprising a fluid duct inlet and a fluid duct outlet, wherein the fluid duct inlet overlaps with the shaft exit opening and the fluid duct outlet overlaps with a coolant duct inlet of a coolant duct reaching through the rotor in the axial direction relative to the axis of rotation, having a coolant duct outlet on its side opposite the coolant duct inlet, through which the coolant emerges from the rotor.

Electric machine

A fluid-cooled rotor for an electric machine and an asynchronous machine with a rotor winding cooled directly or close to a loss.

Fluid-cooled rotor for an electric machine

An electric machine, includes a rotor, a first radial fan wheel and a second radial fan wheel arranged on opposite sides of the rotor in axial direction, a first cooling air chamber and a second cooling air chamber; a first cooling air path extending in axial direction up to a side of the second radial fan wheel which faces away from the first radial fan wheel and from there leading into the second cooling air chamber, a second cooling air path extending in axial direction up to a side of the first radial fan wheel which faces away from the second radial fan wheel and from there leading into the first cooling air chamber, wherein the first radial fan wheel moves cooling air from the first cooling air chamber along the at least one first cooling air path and the second radial fan wheel moves cooling air from the second cooling air chamber along the at least one second cooling air path.
