The invention provides a flat wire stator and a motor. The flat wire stator comprises a stator core and a flat wire winding assembled on the stator core. The stator core comprises a plurality of stator slots, each stator slot is provided with 2M slot layers, the 2M slot layers are arranged along the radial direction of the stator core, the slot layer farthest from the axis of the stator core is the outermost slot layer, and M is a positive integer. The flat wire winding comprises m phases of windings, each phase of winding comprises a wire inlet end and a wire outlet end, the wire inlet ends and the wire outlet ends of the m phases of windings are distributed in a concentrated manner in the circumferential direction of the stator iron core, and the overline mode of at least one phase of winding is that overline is carried out in the same layer at the outermost slot layer at the pitch y1, the groove layers between the outermost groove layer and the innermost groove layer are folded back at a pitch y2 for line
