Abstract: A stator includes conductive wires wound around teeth, and slots between adjacent teeth in a circumferential direction. The conductive wires include conductive wires of three phases corresponding to a U-phase, a V-phase, and a W-phase, and the conductive wires are delta connected. Coils, in which any one of the conductive wires is wound around the teeth, are repeatedly disposed in order of the U-phase, the V-phase, and the W-phase in the circumferential direction. In each of the U-phase, the V-phase, and the W-phase, at least two coils are connected in series and adjacent in the circumferential direction. A direction in which the U-phase and W-phase conductive wires are wound around the teeth and a direction in which the V-phase conductive wire is wound around the tooth are opposite.

Abstract: A manufacturing method comprising: a process S1 of forming a plate member which has a substantially annular scrap portion having a center hole through an axial direction and a core plate portion defining a portion of the core pieces arranged continuously with the scrap portion on a radially inner side of the scrap portion; a process S2 of forming a laminated body, which has the core pieces, by laminating the plate member; a process S3 of providing the laminated body and the shaft in a mold; a process S4 of forming a molding body by inserting a molten resin or a nonmagnetic material in the mold and forming the filling portion of which at least a portion is located between the core pieces; and a process S5 of separating the scrap portion and the core plate portion.
