The invention discloses a stator, a flat wire motor, a power assembly and a vehicle. The stator is characterized in that a stator core is provided with z stator slots; each phase winding in the stator winding comprises a plurality of parallel branches, and each parallel branch comprises a plurality of connected hairpin coils; the span of the first hairpin coil is y, and two supporting legs of the first hairpin coil are located on the (2t-1) th slot layer and the 2t th slot layer respectively; the span of the second hairpin coil is y-1, and two supporting legs of the second hairpin coil are located on the 2t-th slot layer and the 2t + 1-th slot layer respectively; the span of the third hairpin coil is y + 1, and two supporting legs of the third hairpin coil are located on the 2t-th slot layer and the 2t + 1-th slot layer respectively; the span of the fourth hairpin coil is y-1, and two supporting legs of the fourth hairpin coil are located on the nth slot layer; the span of the fifth hairpin coil is y + 1, and two supporting feet of the fifth hairpin coil are both located on the nth groove layer. According to the stator provided by the invention, winding wiring of the stator in the flat wire motor can be realized by using fewer types of hairpin coils, and the manufacturing cost can be reduced.
