Abstract
A fixture for holding a stator including a stator core having a plurality of stator windings during assembly. The fixture includes a first fixture portion including a base defining a first stator receiving portion that is receptive of a first end of the stator, a second fixture portion including second stator receiving portion that is receptive of a second end of the stator, and at least one alignment feature provided on one of the first fixture portion and the second fixture portion. The at least one alignment feature is configurated to establish a selected alignment between a terminal end of each of the plurality of stator windings and busbar.

A fixture for holding a stator including a stator core having a plurality of stator windings during assembly comprising:
- a first fixture portion including a base defining a first stator receiving portion that is receptive of a first end of the stator;
- a second fixture portion including second stator receiving portion that is receptive of a second end of the stator;
- and
- at least one alignment feature provided on one of the first fixture portion and the second fixture portion, the at least one alignment feature being configurated to establish a selected alignment between a terminal end of select ones of the plurality of stator windings and busbar.
A stator assembly comprising:
- a stator fixture including a first fixture portion having a base defining a first stator receiving portion;
- a second fixture portion including a second stator receiving portion;
- a stator including a stator core having a first axial end, a second axial end, a plurality of stator windings including a first end turn that projects from the first axial end and a second end turn that projects from the second axial end, the first end turn being positioned in the first stator receiving portion and the second end turn being positioned in the second stator receiving portion;
- a busbar arranged between the second axial end of the stator core and the second fixture portion;
- and
- at least one alignment feature provided on one of the first fixture portion and the second fixture portion, the at least one alignment feature being configurated to establish a selected alignment between a terminal end of the plurality of stator windings and the busbar.
A method of assembling a stator comprising:
- arranging a first end of the stator at a first stator receiving portion of a first fixture portion;
- positioning a busbar at a second, opposing end of the stator;
- placing a second fixture portion on the second, opposing end of the stator;
- aligning the busbar with terminal end portions of a plurality of stator windings at the second, opposing end of the stator with at least one alignment feature;
- and
- securing the terminal end portions of the plurality of stator windings to the busbar through the second fixture portion.
