摘要： A stator is assembled by stacking, in the axial direction, a plurality of magnetic steel sheets having tooth portions. The steel sheets include connected tooth steel sheets in which the inner-circumferential-side end portions of the tooth portions are connected via connection portions in an annular shape along the circumferential direction, and non-connected tooth steel sheets which are separated from each other with the tooth portions not connected to each other. The connected tooth steel sheets and the non-connected tooth steel sheets are joined to each other in the axial direction via swage portions provided in the tooth portions. The thickness of each connection portion is smaller than the thickness of the other part of each steel sheet.

摘要： A predetermined part of one conductive wire is pressurized and plastically worked to form a slot portion having a desired cross section, a part separated from the slot portion by a predetermined dimension is pressed to form a top portion, and then a part separated from the top portion by a predetermined dimension is plastically worked to form the next slot portion. Through repetition of such steps, a conductive wire in which necessary numbers of slot portions and top portions are formed is manufactured. Using the top portion as a reference, the conductive wire is folded to form a coil end portion and is wound by a plurality of turns into a hexagonal shape, thereby forming a hexagonal coil in which the conductive wire is wound by a predetermined number of turns. In the hexagonal coil, bundles of the slot portions become two opposite sides and are inserted in the slots of the armature.
