Claim 16:
17. The stator module of claim 14, wherein the stator module 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;
in the third winding part, an fth layer of a 2nd slot is a start point of the third winding part, an fth layer of a 26th 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 fth layer of the 2nd slot to an fth layer of a 43th slot construct the thirteenth crossing segment; the fth layer of the 43th slot to an ath layer of the 43th slot construct the fourteenth crossing segment, and in the fourteenth crossing segment, the winding moves back and forth between the 43th slot and the 1st 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 43th slot to an fth layer of a 37th slot construct the fifteenth crossing segment, and in the fifteenth crossing segment, the winding moves back and forth between the 43th slot and the 37th 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 37th slot to an fth layer of a 32nd slot construct the sixteenth crossing segment; the fth layer of the 32nd slot to an ath layer of the 32nd slot construct the seventeenth crossing segment, and in the seventeenth crossing segment, the winding moves back and forth between the 32nd slot and a 38th 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 32nd slot to the fth layer of the 26th slot construct the eighteenth crossing segment, and in the eighteenth crossing segment, the winding moves back and forth between the 32nd slot and the 26th slot and is wound from the inner side of the radial direction to the outer side of the radial direction of the stator core.
