Claim 6:
7. The stator module of claim 1, wherein the phase of the stator winding further comprises:
a second winding coil of each phase of the stator winding comprises a third winding part and a fourth winding part connected end to end, the third winding part constructs a start segment of the second winding coil, and the fourth winding part constructs an end segment of the second winding coil,
wherein in the third winding part, an rth layer of an (n−47)th slot is a start point of the third winding part, an rth layer of an (n−23)th slot is an end point of the third winding part, and the third winding part comprises a thirteenth crossing segment to an eighteenth crossing segment, wherein the rth layer of the (n−47)th slot to an rth layer of an (n−6)th slot construct the thirteenth crossing segment; the rth layer of the (n−6)th slot to an ath layer of the (n−6)th slot is a fourteenth crossing segment, and in the fourteenth crossing segment, the winding moves back and forth between the (n−6)th slot and an nth 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−6)th slot to an rth layer of an (n−12)th slot construct the fifteenth crossing segment, and in the fifteenth crossing segment, the winding moves back and forth between the (n−6)th slot and the (n−12)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−12)th slot to an rth layer of an (n−17)th slot construct the sixteenth crossing segment; the rth layer of the (n−17)th slot to an ath layer of the (n−17)th slot construct the seventeenth crossing segment, and in the seventeenth crossing segment, the winding moves back and forth between the (n−17)th slot and an (n−11)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−17)th slot to the rth layer of the (n−23)th slot construct the eighteenth crossing segment, and in the eighteenth crossing segment, the winding moves back and forth between the (n−17)th slot and the (n−23)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.
