Abstract
A method for joining segments (electrical conductors) includes first and second joining steps. The first joining step includes welding a group of the segments including ends, such that the first group is welded to pairs of electrical conductors. The second joining step includes welding a second group of the segments including ends, which are composed of the segments whose ends are arranged in a column in the radial direction, such that the second group is welded to pairs of electrical conductors. The first group includes a segment as a first electrical conductor including the end which is located at the middle portion of a group of the segments including the ends in the radial direction. The second group includes a segment as a second electrical conductor including the end which crosses the first electrical conductor on the opposite sides with respect to the middle portion in the radial direction.
