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 system for cooling an electric machine having two components, one of the two components rotor and the other a stator, the two components enclosing a central axis of the electric machine coaxially, The rotor during operation of the electric machine rotates relative to the stator, wherein at least one axially oriented channel passes through at least one component. A fan is arranged at a first end of the at least one channel, wherein a turbine is arranged at a second end of the at least one channel. The fan is designed to enable air to flow, flowing from the first end through the at least one axially oriented channel to the second end.

System for cooling an electric machine

An electric machine provided with a stator and with a rotor arranged on a coolable shaft which is rotatably mounted with respect to the stator. The rotor is connected to the shaft by a thermosiphon device which is non-rotatably connected to the rotor and arranged on the front side of the rotor.
