Abstract:
A stator assembly is provided that simplifies the process of coupling the stator windings to the winding lugs. The stator assembly includes a pre-fabricated connector that is attached to the stator via a plurality of stator winding terminations. The pre-fabricated connector includes a plurality of electrically conductive termination coupling members that form conductive pathways between at least a portion of the stator winding terminations and a plurality of bus bars, where each of the bus bars includes a lug. The pre-fabricated connector may also include a second plurality of electrically conductive termination coupling members that form conductive pathways between at least a second portion of the stator winding terminations and a plurality of lugless bus bars. An electrically insulating material is overlaid over portions of the connector ring, thereby preventing contact or partial discharge between the various bus bars.
