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.
