The invention relates to a double-layer flat wire winding structure of a motor, which comprises a stator iron core and a three-phase flat wire winding arranged in the stator iron core, insulation paper is arranged between the stator iron core and the flat wire winding, the stator iron core is provided with Z wire slots, the slot number of each pole and each phase of the stator iron core is set as q, i flat conductors are embedded in each slot of the stator iron core, each phase of the winding comprises a plurality of parallel branches, each parallel branch is formed by connecting a plurality of hairpin flat conductors in series, each hairpin flat conductor is provided with an input side and an output side, the hairpin flat conductors are sequentially embedded into the stator iron core at equal pitches, a short-distance winding is formed by twisting a welding end, and each parallel branch is completely symmetrically distributed on a magnetic circuit. According to the invention, all input sides and output sides
