Abstract:
A stator of an alternator having a rotor rotating in the stator, the stator comprising:a cylindrical stator core having a plurality of slots formed along an inner bore of the stator core; and a stator coil formed by connecting a plurality of U-shaped conductor segments, each U-shaped conductor segment comprising: a pair of straight conductor portions; a pair of first slanted portions each connected to one end of each straight conductor portion; a turning portion connecting the pair of first slanted portions; and a pair of second slanted portions each connected to the other end of each straight conductor portion, wherein: the straight conductor portions are accommodated in the slots, the first slanted portions and the turning portions extend to one side of the slots forming a first coil end, and the second slanted portions extend to the other side of the slots and are connected to one another forming a second coil end; the turning portion of each U-shaped conductor segment has a substantially round cross-section, and the conductor portions and the slanted portions of each U-shaped conductor segment have a rectangular cross-section thereby providing a larger space between neighboring turning portions than between neighboring slanted portions; and all the portions of each U-shaped conductor segment have a same cross-sectional area.
