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.
