Abstract (en)

[origin: WO2016050534A1] The invention relates to an electric machine (1, 51), in particular an asynchronous machine, which comprises a stator (2), a rotatably mounted rotor (4) with a shaft (5), and a flow guiding element (7). Said shaft (5) comprises an axial borehole (6). Said flow guiding element (7) extends in such a manner in the axial borehole (6) such that a coolant (15), in particular a cooling liquid (15), can flow out from the flow guiding element (7, 47) into the borehole (6) or vice versa. A slide ring seal (40) seals the opening of the axial borehole (6). When the electrical machine (1, 51) is in operation, a value can be determined for the humidity in a cavity (55) of the electric machine (1, 51) .
