Abstract

An electric machine has a stator, a rotor, and a slip ring module which is connected to a motor shaft of the electric machine. The slip ring module is equipped with at least one wire guiding channel, through which a respective contact wire is guided in order to electrically connect a rotor winding to a slip ring. A first section of the wire guiding channel runs from the slip ring in the axial direction parallel to the motor shaft. A second section of the wire guiding channel runs adjacently thereto radially outwards. An elastic seal element which surrounds the respective contact wire is arranged in or on the second section in order to seal the wire guiding channel to prevent a lubricant from entering the channel.
