End cap for use in a stator assembly and method of assembling the stator assembly

1. An end cap for use with a stator assembly, said end cap comprising:

a tooth portion including a first end and an opposite second end;

a yoke portion formed at the first end of said tooth portion, said yoke portion comprising at least one arm portion that extends from said tooth portion; and

a lip extending along said tooth portion and said at least one arm portion such that a first receiving surface is defined on said tooth portion and such that a second receiving surface is defined on said at least one arm, wherein said first receiving surface and said second receiving surface are oriented to face the same direction.

2. The end cap in accordance with claim 1 , wherein said lip extends from at least one of said tooth portion and said at least one arm portion.

3. The end cap in accordance with claim 1 , wherein the end cap further comprises an indentation defined within each of said tooth portion and said at least one arm portion, said indentation defining said lip.

4. The end cap in accordance with claim 1 , wherein said tooth portion comprises a substantially rounded shape.

5. The end cap in accordance with claim 1 , wherein the end cap further comprises a foot portion extending from the second end of said tooth portion.

6. The end cap in accordance with claim 1 , wherein the end cap comprises a non-conductive material.

7. A stator assembly including at least one stator segment, the stator assembly comprising:

a core comprising a tooth that comprises at least one end face;

an end cap positioned adjacent said at least one end face, said end cap comprising:

a tooth portion including a first end and an opposite second end;

a yoke portion formed at the first end of the tooth portion, said yoke portion comprising at least one arm portion that extends from said tooth portion; and

a lip extending along said tooth portion and said at least one arm portion such that a first receiving surface is defined on said tooth portion and such that a second receiving surface is defined on said at least one arm, wherein said first receiving surface and said second receiving surface are oriented to face the same direction;

an insulation member coupled to said end cap, said insulation member comprising a first end and a second end opposite said first end, wherein at least one of said first end and said second end are positioned against said first receiving surface and said second receiving surface; and

a wire wound about said core tooth such that said end cap is positioned between said core tooth and said wire.

8. The stator assembly in accordance with claim 7 , wherein a cavity is defined between an inner surface of said end cap and said at least one end face, said cavity extending a length of said end cap tooth portion.

9. The stator assembly in accordance with claim 8 , wherein said cavity has a semi-circular cross-sectional shape.

10. The stator assembly in accordance with claim 8 , wherein said cavity is configured to receive at least one of a portion of a tie member and a first member of a tool.

11. The stator assembly in accordance with claim 7 , wherein said end cap further comprises a foot portion extending from the second end of said tooth portion, said foot portion configured to retain wire therein.

12. The stator assembly in accordance with claim 7 , wherein said end cap further comprises:

a central portion defined at the first end of said tooth portion, said central portion comprising a fastener aperture;

a foot portion extending from the second end of said tooth portion, said foot portion comprising a notch; and

a tie member circumscribing said end cap, said tie member engaged with said fastener aperture and said notch.

13. The stator assembly in accordance with claim 12 , further comprising a lead wire secured to at least one of said wire and said at least one end cap by said tie member.

14. The stator assembly in accordance with claim 7 , wherein said lip extends from at least one of said at least one arm portion and said tooth portion such that said lip does not extend into a slot defined between adjacent stator segments when said end cap is positioned adjacent said at least one end face of said core tooth.
