Claim 7:
8. The stator module of claim 7, wherein in the fourth winding part, the rth layer of the (n−23)th slot is a start point of the fourth winding part, a secondary outer layer of an (n−41)th 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 rth layer of the (n−23)th slot to an rth layer of an (n−30)th slot construct the nineteenth crossing segment; the rth layer of the (n−30)th slot to an ath layer of the (n−30)th slot construct the twentieth crossing segment, and in the twentieth crossing segment, the winding moves back and forth between the (n−30)th slot and an (n−24)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 (n−30)th slot to an rth layer of an (n−36)th slot construct the twenty-first crossing segment, and in the twenty-first crossing segment, the winding moves back and forth between the (n−30)th slot and the (n−36)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 (n−36)th slot to an rth layer of the (n−41)th slot construct the twenty-second crossing segment; the rth layer of the (n−41)th slot to an ath layer of the (n−41)th slot construct the twenty-third crossing segment, and in the twenty-third crossing segment, the winding moves back and forth between the (n−41)th slot and an (n−35)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 (n−41)th slot to the secondary outer layer of the (n−41)th slot construct the twenty-fourth crossing segment, and in the twenty-fourth crossing segment, the winding moves back and forth between the (n−41)th slot and the (n−47)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,
wherein n is an integer greater than 47.
