Claim 17:
18. The stator module of claim 17, wherein in the fourth winding part, the fth layer of the 26th slot is a start point of the fourth winding part, a secondary outer layer of an 8th slot is an end point of the fourth winding part, and the fourth winding part comprises a nineteenth crossing segment to a twenty-fourth crossing segment, wherein the fth layer of the 26th slot to an fth layer of a 19th slot construct the nineteenth crossing segment; the fth layer of the 19th slot to an ath layer of the 19th slot construct the twentieth crossing segment, and in the twentieth crossing segment, the winding moves back and forth between the 19th slot and the 25th 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 19th slot to an fth layer of the 13th slot construct the twenty-first crossing segment, and in the twenty-first crossing segment, the winding moves back and forth between the 19th slot and the 13th 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 13th slot to an fth layer of the 8th slot construct the twenty-second crossing segment; the fth layer of the 8th slot to an ath layer of the 8th slot construct the twenty-third crossing segment, and in the twenty-third crossing segment, the winding moves back and forth between the 8th slot and the 14th 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 8th slot to the secondary outer layer of the 8th slot construct the twenty-fourth crossing segment, and in the twenty-fourth crossing segment, the winding moves back and forth between the 8th slot and the 2nd slot and is wound from the inner side of the radial direction to the outer side of the radial direction of the stator core.
