Abstract: A stator includes a stator core and a stator winding. An inner wall of the stator core is provided with M winding slots, the M winding slots are uniformly disposed in a circumferential direction of the inner wall of the stator core. The stator winding includes flat wire conductors inserted in the winding slots, N layers of flat wire conductors are disposed in any one of the winding slots, and phase units of a first-phase winding, phase units of a second-phase winding, and phase units of a third-phase winding are sequentially and periodically arranged along the inner wall of the stator core. Each phase winding includes P parallel branches. Any one of the parallel branches connects flat wire conductors of M·N/3P layers.
