Abstract

A method for forming an article is presented. The method includes providing one or more ceramic insulators having one or more recesses, providing a plurality of conductors within the one or more recesses of the one or more ceramic insulators, and joining a first conductor of the plurality of conductors to a second conductor of the plurality of conductors.

First claim

1 . A method for forming an article comprising:
providing one or more ceramic insulators having one or more recesses; providing a plurality of conductors within the one or more recesses of the one or more ceramic insulators; and joining a first conductor of the plurality of conductors to a second conductor of the plurality of conductors.

2 . The method according to claim 1 , wherein the providing the one or more ceramic insulators comprises forming the one or more ceramic insulators.

3 . The method according to claim 1 , wherein the providing the plurality of conductors comprises disposing the plurality of conductors within the one or more recesses of the one or more ceramic insulators.

4 . The method according to claim 1 , wherein the providing the plurality of conductors comprises forming at least one conductor of the plurality of conductors within the one or more recesses of the one or more ceramic insulators.

5 . The method according to claim 1 , wherein the joining step comprises joining the first conductor to the second conductor using a first joining media.

6 . The method according to claim 1 , further comprises joining a first ceramic insulator of the one or more ceramic insulators to a second ceramic insulator of the one or more ceramic insulators after providing the plurality of conductors within the one or more recesses of the one or more ceramic insulators.

7 . The method according to claim 6 , wherein the joining step comprises joining the first ceramic insulator to the second ceramic insulator using a second joining media.

8 . The method according to claim 6 , wherein the joining step comprises joining the first ceramic insulator to the second ceramic insulator using a third ceramic insulator.

9 . The method according to claim 6 , wherein the joining step comprises joining the first ceramic insulator to the second ceramic insulator at a temperature in a range from about 200 degrees Celsius to about 800 degrees Celsius.

10 . An article comprising:
one or more ceramic insulators having one or more recesses; and a plurality of conductors disposed in the one or more recesses of the one or more ceramic insulators, wherein a first conductor of the plurality of conductors is joined to a second conductor of the plurality of conductors.

11 . The article according to claim 10 , wherein the one or more ceramic insulators have a monolithic structure.

12 . The article according to claim 10 , wherein the one or more ceramic insulators comprise alumina, zirconia or a combination thereof.

13 . The article according to claim 10 , wherein an exterior surface of each of the plurality of conductors conforms to an interior surface of the one or more recesses of the one or more ceramic insulators.

14 . The article according to claim 10 , wherein a cross-sectional shape of the plurality of conductors varies along a length of the plurality of conductors, and wherein the plurality of conductors is configured to conduct an electric current.

15 . The article according to claim 10 , wherein the plurality of conductors comprises a metal selected from the group consisting of copper, silver, gold, aluminum and combinations thereof.

16 . The article according to claim 10 , wherein at least one conductor of the plurality of conductors defines a cooling channel extending through the at least one conductor.

17 . The article according to claim 10 , wherein the one or more ceramic insulators define one or more cooling channels extending through the one or more recesses.

18 . A system comprising:
a stator comprising the article of claim 1 ; and a rotor, wherein the rotor is configured to rotate relative to the stator.

19 . The system according to claim 18 , wherein the stator comprises a stator body comprising a magnetic material disposed on the article.

20 . The system according to claim 19 , wherein the stator comprises a semiconductive material, a conductive material or a combination thereof disposed on a surface of the article between the stator body and the article.
