Abstract
The present invention relates to an electric machine (1) having a rotor (3) and a stator (2), wherein the stator (2) and/or the rotor (3) has an electrical plug-in winding (4), which comprises a plurality of rigid insulated electrical conductor elements (5); the conductor elements (5) are arranged in grooves of the stator or of the rotor and their conductor ends (17) project out of the grooves; the conductor ends of the conductor elements (5) are each connected to conductor ends of other conductor elements (5) in order to form the electrical plug-in winding (4); the conductor elements (5) have an electrically insulating insulation sheath (9); characterized in that each conductor element (5) has a multiplicity of flexible fibres (8), in particular of a conductor strand of flexible fibres (8), made of carbon nanotubes or graphene and in that the insulation sheath (9) surrounds the multiplicity of fibres (8) like a hose and is designed in such a way that it gives the electrical conductor element (5) a rigid form.
