Abstract
An electric machine and a stator assembly include a segmented stator having stator portions. Each stator portion includes end plates arranged axially on opposing sides of the stator portion, support plates arranged interior to the end plates, stator laminations arranged between the support plates, and stabilizing elements coupling the end plates and the support plates together. Each of the stabilizing elements has a dovetail portion coupled to the end plates and to the support plates. Connectors are provided to connect the stator portions of the segmented stator together.
