Zusammenfassung:A motor stator includes a stator core having stator slots, and a stator winding inserted into the stator slots. Each stator slot includes slot layers. The stator winding includes first and second conductors each including two straight segment parts. The straight segment parts of the first conductors are separately located at two adjacent slot layers. One straight segment part of the second conductor and one straight segment part of the first conductor are located in a same stator slot. A pole pitch of the stator winding is τ, a size of a pitch of the second conductor is y2, a distance between straight segment parts of two adjacent first conductors at a same slot layer is L1, a distance between straight segment ends of adjacent second conductors at a same slot layer is L2, and the followings are met: L1=τ+1 or L1=τ−1, and L2=2τ−y2.
