Claim 14:
15. The stator module of claim 14, wherein the first winding coil further comprises a second winding part constituting an end segment of the first winding coil,
wherein in the second winding part, the fth layer of the 25th slot is a start point of the second winding part, a secondary outer layer of a 7th slot is an end point of the second winding part, and the second winding part comprises a seventh crossing segment to a twelfth crossing segment, wherein the fth layer of the 25th slot to an fth layer of a 20th slot construct the seventh crossing segment; the fth layer of the 20th slot to an ath layer of the 20th slot construct the eighth crossing segment, and in the eighth crossing segment, the winding moves back and forth between the 20th slot and a 26th slot and is wound from the outer side of the radial direction to the inner side of the radial direction of the stator core; the ath layer of the 20th slot to an fth layer of a 14th slot construct the ninth crossing segment, and in the ninth crossing segment, the winding moves back and forth between the 20th slot and the 14th slot and is wound from the inner side of the radial direction to the outer side of the radial direction of the stator core; the fth layer of the 14th slot to an fth layer of the 7th slot construct the tenth crossing segment; the fth layer of the 7th slot to an ath layer of the 7th slot construct the eleventh crossing segment, and in the eleventh crossing segment, the winding moves back and forth between the 7th slot and a 13th slot and is wound from the outer side of the radial direction to the inner side of the radial direction of the stator core; and the ath layer of the 7th slot to the secondary outer layer of the 7th slot construct the twelfth crossing segment, and in the twelfth crossing segment, the winding moves back and forth between the 7th slot and the 1st slot and is wound from the inner side of the radial direction to the outer side of the radial direction of the stator core.
