Abstract

The electric machine comprises at least one winding (30) having at least one conductor (20) and electrical insulation for insulating one or more of the windings (30) and/or conductors (20), wherein the insulation is formed by a metal oxide. The method for producing such an electric machine having at least one winding (30) having at least one conductor (20) comprises the steps of metallizing the at least one winding (30) and/or conductor (20) with metal and oxidizing the metal. The aircraft is in particular an electric or hybrid-electric aircraft and has such an electric machine (10).
