Abstract: The present invention relates to a slip ring assembly for providing electricity to or from a rotor rotating in relation to a stator in a generator or an electrical motor. The slip ring unit rotates around a centre axis and has at least one first slip ring with an outer surface, a diameter, and a width. Also, the assembly has at least one conductive means, such as a brush, having conductive contact with the surface of the slip ring, and a housing in which the slip ring unit and the conductive means are situated. Furthermore, the assembly has a suction means in connection with the housing for suction of gas from within the housing out through a suction outlet in the housing. In addition, the housing has a suction inlet which is connected with a guiding means. The guiding means has an aperture facing the slip ring surface, and the aperture is positioned at a predetermined distance from the surface of the slip ring so that the gas is able to cool the surface of the slip ring.

Abstract: The present invention relates to a slip ring assembly for providing electricity to a rotor which is able to rotate in relation to a stator in a generator or an electrical motor, the slip ring assembly being in connection with an encoder. The slip ring assembly includes a slip ring unit having at least one first slip ring, and an encoder shaft holder connected to the slip ring unit and in which holder an encoder shaft is situated. The encoder shaft holder is made from an electrically insulating material for providing an electrical insulation between the slip ring unit and the encoder.

Abstract: The present invention relates to a slip ring assembly 1 for providing electricity to a rotor which is able to rotate in relation to a stator in a generator or an electrical motor, the slip ring assembly being in connection with an encoder 4. The slip ring assembly 1 comprises a slip ring unit 2 having at least one first slip ring 3, and an encoder shaft holder 6 connected to the slip ring unit and in which holder an encoder shaft 5 is situated. The encoder shaft holder 6 is made from an electrically insulating material for providing an electrical insulation between the slip ring unit 2 and the encoder 4.
