1. A method comprising providing a plurality of stacked stator segments, wherein the stacked stator segments include a generally circumferential outer surface having a channel defined therein, the channel being partially defined by a relatively flat bottom surface, placing a filler sheet in the channel with a flat surface of the filler sheet against the flat bottom surface, and welding the filler sheet to the stack of stator segments to hold the stack of stator segments together.
