Claim Text:
1. A method of assembling a stator for an electrical machine having an axis of rotation, said method comprising: aligning a plurality of laminations wherein each lamination includes a slot; coupling a plurality of keys to the plurality of laminations; coupling a fixture to the plurality of keys; utilizing the fixture to move a first tab and a second tab of each key of the plurality of keys from a first position to a second position to facilitate coupling together the plurality of laminations, wherein the first tab and the second tab extend beyond opposing axial end surfaces of the plurality of laminations in at least the first position when the stator is in an operational configuration; and indexing the plurality of keys to facilitate forming at least one planar surface that is positioned orthogonal to the axis of rotation, wherein the planar surface includes an axially outer surface of the plurality of keys.
