Claim 4:
5. The stator module of claim 1, 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 rth layer of the (i−24)th slot is a start point of the second winding part, a secondary outer layer of an (i−42)th 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 rth layer of the (i−24)th slot to an rth layer of an (i−29)th slot construct the seventh crossing segment; the rth layer of the (i−29)th slot to an ath layer of the (i−29)th slot construct the eighth crossing segment, and in the eighth crossing segment, the winding moves back and forth between the (i−29)th slot and an (i−23)th 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 (i−29)th slot to an rth layer of an (i−35)th slot construct the ninth crossing segment, and in the ninth crossing segment, the winding moves back and forth between the (i−29)th slot and the (i−35)th 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 rth layer of the (i−35)th slot to an rth layer of the (i−42)th slot construct the tenth crossing segment; the rth layer of the (i−42)th slot to an ath layer of the (i−42)th slot construct the eleventh crossing segment, and in the eleventh crossing segment, the winding moves back and forth between the (i−42)th slot and an (i−36)th 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 (i−42)th slot to the secondary outer layer of the (i−42)th slot construct the twelfth crossing segment, and in the twelfth crossing segment, the winding moves back and forth between the (i−42)th slot and the imth slot and is wound from the inner side of the radial direction to the outer side of the radial direction of the stator core,
wherein i is an integer greater than 42.
