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).
Claims19
An electric machine comprising:
- at least one winding including:
- at least one conductor;
- first electrical insulation for insulating the at least one winding, the first electrical insulation including plastic material with a surface layer with a first metal oxide;
- and
- second electrical insulation in the at least one conductor, the second electrical insulation including a second metal oxide.
A method for producing an electric machine having at least one winding with at least one conductor and electrical insulation for insulating one or more windings of the at least one winding, the method comprising:
- metallizing a plastic material of the electrical insulation of the at least one winding with metal;
- and
- oxidizing the metal, such that a surface layer of metal oxide is formed.
An aircraft comprising:
- an electric machine comprising:
- at least one winding including:
- at least one conductor;
- first electrical insulation for insulating the at least one winding, the first electrical insulation including plastic material with a surface layer with a first metal oxide;
- and
- second electrical insulation in the at least one conductor, the second electrical insulation including a second metal oxide.
An electric machine comprising:
- at least one winding including:
- at least one strand comprising at least one conductor and electrical insulation for insulating one or more windings of the at least one winding;
- and
- a sheath with the metal oxide,
- wherein the sheath is a shrink hose with the metal oxide.
