Abstract: A stator module (10) and a motor are provided. The stator module (10) includes a stator core (1) and a stator winding (2). The stator core (1) includes a plurality of stator slots (11), and the plurality of stator slots (11) are distributed in a circumferential direction of the stator core (1). A first winding coil (21) of each phase of the stator winding (2) includes a first winding part (211) and a second winding part (212) connected end to end, the first winding part (211) includes a first crossing segment (2111) to a sixth crossing segment (2116), and the second winding part (212) includes a seventh crossing segment (2121) to a twelfth crossing segment (2126). A second winding coil (22) of each phase of the stator winding (2) includes a third winding part (221) and a fourth winding part (222) connected end to end.

Abstract: A stator module is applicable to a motor. The motor comprises z slots, 2p poles, and m phases, where z, p, and m are integers. The stator module includes a stator core and a stator winding. The stator core has multiple stator slots, and the stator slots are distributed in a circumferential direction of the stator core. The stator winding includes a first-class conductor segment, a second-class conductor segment, and a third-class conductor segment. A pitch between a first in-slot portion and a second in-slot portion of the first-class conductor segment is (y−1) stator slots, a pitch between a first in-slot portion and a second in-slot portion of the second-class conductor segment is y stator slots, and a pitch between a first in-slot portion and a second in-slot portion of the third-class conductor segment is (y+1) stator slots, where y is an integer and y=z/2p.
