Abstract

The present application provides a stator. The stator may include a number of poles and a stator tip and cooling assembly. The stator tip and cooling assembly may include a number of stator tips with a number of cooling tubes adjacent thereto such that the stator tips align with the poles and the cooling tubes cool the poles.

Claims (22)

1. A stator, comprising:

a plurality of poles; and

a stator tip and cooling assembly;

the stator tip and cooling assembly comprising a plurality of stator tips with a plurality of cooling tubes adjacent thereto such that the plurality of stator tips aligns with the plurality of poles and the plurality of cooling tubes cools the plurality of poles.

2. The stator of claim 1 , wherein each of the plurality of poles comprises a tooth and a coil and wherein the each of the plurality of stator tips aligns with a tooth and wherein each of the plurality of cooling tubes aligns with a coil.

3. The stator of claim 1 , wherein the stator tip and cooling assembly comprises a plurality of spacers positioned between the plurality of stator tips.

4. The stator of claim 3 , wherein each of the plurality of spacers comprises a cooling channel therein and wherein the plurality of cooling tubes are positioned within the cooling channels.

5. The stator of claim 3 , where the plurality of stator tips and the plurality of spacers comprise a ring subassembly.

6. The stator of claim 3 , wherein the plurality of spacers comprises an epoxy spacer.

7. The stator of claim 1 , further comprising an outer cooling jacket positioned thereon.

8. The stator of claim 7 , further comprising a cooling manifold in communication with the stator tip and cooling assembly and the outer cooling jacket.

9. The stator of claim 1 , further comprising a stack and wherein the plurality of poles extends therefrom.

10. An electrical device, comprising:

a rotor; and

a stator positioned about the rotor;

the stator comprising a plurality of poles and a stator tip and cooling assembly to cool the plurality of poles; where each pole includes a tooth and wherein the stator tip and cooling assembly is in flush contact with each tooth.

11. The electrical device of claim 10 , wherein the stator tip and cooling assembly comprises a plurality of stator tips with a plurality of cooling tubes adjacent thereto.

12. The electrical device of claim 11 , wherein each of the plurality of poles further comprises a coil and wherein the each of the plurality of stator tips aligns with a tooth and wherein each of the plurality of cooling tubes aligns with a coil.

13. The electrical device of claim 11 , wherein the stator tip and cooling assembly comprises a plurality of spacers positioned between the plurality of stator tips.

14. The electrical device of claim 13 , wherein each of the plurality of spacers comprises a cooling channel therein and wherein the plurality of cooling tubes are positioned within the cooling channels.

15. The electrical device of claim 10 , wherein the stator comprises an outer cooling jacket positioned thereon.

16. The electrical device of claim 15 , wherein the stator comprises a cooling manifold in communication with the stator tip and cooling assembly and the outer cooling jacket.
