Abstract:
In a stator coil of a rotary electric machine, a first crank portion radially shifts one side of a turn portion from the other side thereof by a first length. The one side extends to one of paired straight portions, and the other side extends to the other thereof. A second crank portion radially shifts one side of a turn portion from the other side thereof by a second length. The one side extends to one of the paired straight portions, and the other side extends to the other thereof. The first length is equivalent to a radial width of the turn portion of the first segment of each set. The second length allows the second crank portion of the second segment of each of the sets to substantially overlay the first crank portion of the first segment of each set.
