Beschreibung
Zusammenfassung:	In a collector device for supplying an electric power to a rotor of a motor with a cooling by a cooling medium, an annular collector electrode is fixed to the rotor to supply the electric power to the rotor through a cylindrical outer surface of the collector electrode, an electrically conductive brush is contactable with the cylindrical outer surface of the collector electrode to supply the electric power to the collector electrode, and a cooling medium outlet opens to at least partially face to the collector electrode in such a manner that the cooling medium is supplied from the outlet to the collector electrode in each of circumferential directions of the rotor opposed to each other circumferentially to be divided into two flow parts in respective circumferential directions of the rotor opposed to each other circumferentially.
