1. 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), wherein the conductor elements (5) are arranged in grooves of the stator (2) or the rotor (3) and project out of the grooves with conductor ends (17), wherein the conductor ends (17) of the conductor elements (5) are each connected to conductor ends (17) of other conductor elements (5) to form the electrical plug-in winding (4), wherein the conductor elements (5) each have an electrically insulating insulation sheath (9), tubularly surrounding a multiplicity of flexible fibers (8), and wherein the insulation sheath (9) is configured to give the electrical conductor element (5) a rigid form.
