1. A stator core, comprising:
- a first lamination formed from a plurality of first segments, and having a plurality of first mounting ears;
a second lamination formed from a plurality of second segments, and having a plurality of second mounting ears, wherein the first lamination and the second lamination are aligned with a common axis and are rotated about the common axis such that the first lamination is not angularly orthogonal relative to the second lamination;
wherein each of the first segments and the second segments further includes;
a body;
a first mounting tab extending from the body;
a second mounting tab extending from the body, wherein the first mounting tab and second mounting tab cooperate to form the first and second mounting ears and cooperate to define a mounting slot, which is closed proximal to the body and open distal to the body;
a first end having a first joint;
a second end having a second joint, wherein the second joint is configured to mate with the first joint;
a plurality of teeth extending from the body opposite the first mounting tab and the second mounting tab;
wherein the first mounting tab of the first segments is located on the first end adjacent the first joint;
wherein the second mounting tab of the first segments is located on the second end adjacent the second joint, such that the first mounting ears are formed adjacent to the first joint and the second joint; and
wherein the mounting slot is configured to interface with a locating feature, and wherein the first mounting tab and the second mounting tab do not fully surround the locating feature.

Abstract
A stator core includes a first lamination and a second lamination. The first lamination is formed from a plurality of first segments and has a plurality of first mounting ears. The second lamination is formed from a plurality of second segments and has a plurality of second mounting ears. The first lamination and the second lamination are aligned with a common axis and are rotated about the common axis such that the first lamination is not aligned with the second lamination.

8. A stator core, comprising:
-
a plurality of first laminations formed from a plurality of first segments having a plurality of first mounting ears; a plurality of second laminations formed from a plurality of second segments having a plurality of second mounting ears; wherein the first mounting ears and the second mounting ears define a plurality of mounting slots, which are closed proximal to the first segments and the second segments and open distal to the first segments and the second segments; wherein the mounting slots defined by the first mounting ears of the first segments are located at a joint between adjacent first segments; and wherein the first laminations and the second laminations are aligned with a common axis and are rotated about the common axis such that the first laminations are angularly offset relative to the second laminations. - View Dependent Claims (9, 10, 11, 12)
