Abstract
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.
