Beschreibung
Zusammenfassung:	A device for collecting the liquid cooling medium of an electric machine rotor winding which comprises an external cylindrical member having an annular recess on its internal surface fastened to the rotor in communication with the cooling medium discharge from the rotor winding, and a stationary internal cylindrical member having an external surface provided with an annular projection, extending into the annular recess of the external cylindrical member, both members being arranged concentrically with a rotor shaft. The annular projection is provided with at least one internal annular cavity open on the circumference of the projection and communicating with the liquid collecting chamber.
