Abstract
A high-temperature insulation assembly for use in high-temperature electrical machines and a method for forming a high-temperature insulation assembly for insulating conducting material in a high-temperature electrical machine. The assembly includes a polymeric film and at least one ceramic coating disposed on the polymeric film. The polymeric film is disposed over conductive wiring or used as a conductor winding insulator for phase separation and slot liner.
Claims25
A high-temperature insulation assembly, comprising:
- a polymeric film;
- and
- at least one ceramic coating disposed on at least one side of the polymeric film, thereby forming the high-temperature insulation assembly for use in electrical machines;
- wherein the high-temperature insulation assembly is disposed on conductive wiring or used as an insulator providing protection against voltage hazards or for inhibiting leakage of current, electric discharge and/or a short circuit current.
An electrical machine, comprising:
- a motor or generator comprising conductive wiring wound in non-planar orientations;
- and
- a high-temperature insulation assembly for insulating the conductive wiring and conductive bodies of the motor or the generator, said insulation assembly comprising:
- a polymeric film;
- at least one ceramic coating disposed on at least one side of the polymeric film, thereby forming the high-temperature insulation assembly for use in electrical machines;
- wherein the high-temperature insulation assembly is disposed on the conductive wiring or used as an insulator between windings and magnetic materials.
A method for forming a high-temperature insulation assembly, comprising:
- depositing at least one layer of a ceramic material on a polymeric film;
- and
- disposing the at least one layer of a ceramic material and the polymeric film thereby forming the insulation assembly, wherein the insulation assembly is located proximate a conducting material in an electrical machine.
