1. An alignment plate for mounting a busbar assembly to a stator, the stator including a winding arrangement with a plurality of stator leads projecting from a stator core and a plurality of end turns at a top surface of the stator core, wherein the stator core is cylindrical with an inner perimeter surface and an outer perimeter surface, the busbar assembly including a busbar body carrying a plurality of lead connectors corresponding to the plurality of stator leads, the alignment plate comprising:
a rigid base plate having a planar bottom face configured to be seated on the end turns and an opposite top face configured to receive the busbar body mounted thereon, wherein said rigid base plate is arcuate with an inboard edge and an opposite outboard edge that are generally contiguous with or between the inner and outer perimeter surfaces, respectively, when the base plate is seated on the end turns; and
a plurality of openings defined through said base plate, said plurality of openings corresponding to said plurality of stator leads and arranged on said base plate to be aligned with and receive the plurality of stator leads when the bottom face is seated on the end turns, each opening of said plurality of openings sized and configured for a close running fit with a corresponding one or a corresponding pair of said stator leads aligned with said opening.
