摘要： A stator provided with annular split stator cores, formed by stacking steel plates. Each plate includes a yoke and a stator tooth. The cores include a yoke portion a stator tooth portion. The stator is manufactured by arranging an electromagnetic steel plate between a first die and a second die. The first die has a hole shaped as a steel plate. The second die has a projection inserted into the hole and shaped as a steel plate. The steel plates are formed by the first and the second dies. In a gap between an inner surface of the first die that defines the hole and an outer surface of the projection, a gap at a part that forms the stator tooth portion is larger than a gap at a part that defines a circumferential end surface of the yoke portion located in a circumferential direction of the stator core.
