A multi-layer hairpin type flat wire winding stator comprises a stator core and a hairpin flat wire wave winding. Stator slots are arranged in the stator core, and the hairpin flat wire wave winding is embedded in the stator slots. The hairpin flat wire wave winding comprises more than two branches. The stator slots where three-phase windings of the hairpin flat wire wave winding are located are arranged in a pairwise spaced mode and sequentially arranged. Any branch is changed to an equivalent slot of the adjacent stator slot after circling by half of layers on the circumference, and long-distance or short-distance connection is adopted when the branch is changed to the equivalent slot of the adjacent stator slot in a cross-layer mode, so that the head end and the tail end of any branch are located on the innermost layer and the outermost layer in the radial direction of the stator. Long-distance or short-distance connection occurs only when cross-layer transposition is performed to equivalent slots of adjacent stator slots, so that the head ends and the tail ends of the branches are located on the innermost layer and the outermost layer in the radial direction of an armature, and a single branch of each phase can pass through equivalent positions of all layers of all the stator slots of the phase where the single branch is located.
