Abstract
A stator for an electric machine includes a plurality of core segments interconnected with one another. At least one core segment includes a plurality of teeth and a back portion that at least partially interconnects the teeth. A first one-piece mold defines a first end insulator portion and a plurality of slot insulator portions, and a second one-piece mold defines a second end insulator portion and a second plurality of slot insulator portions. The plurality of core segments is positioned between the first mold and the second mold such that the molds align and insulate the core portions. The stator also includes a plurality of coils. Each coil surrounds at least a portion of one tooth.
