Abstract:
A stator of an electric motor includes a multilayer body including annular core sheets stacked in layers. A first annular core sheet includes linking portions, each of which defines a link between tips of two adjacent teeth and includes a seam. A first linking portion provides a link between teeth associated with a U phase. A second linking portion provides a link between teeth associated with a V phase. A third linking portion provides a link between teeth associated with a W phase.
