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.

摘要： This method includes: a coil assembly step of combining a plurality of coil units to form a coil basket; a core insertion step of inserting inner cores of in the radial direction to the coil basket; and a fixation member insertion step of inserting a fixation member to the outer circumference of the inner core. In the core insertion step, the radial-direction position of the coil basket is retained at a core insertion time position shifted outward in the radial direction relative to a normal position after armature completion, and the inner cores are inserted in the radial direction to the coil basket. After the core insertion step, the radial-direction positions of the coil basket and the inner cores are moved inward in the radial direction to the normal position after armature completion.
