Abstract: A six-phase flat wire wave winding structure. Each phase of wave winding structure has a wire-in end, a wire-out end, and a wire located between the wire-out end and the wire-in end. The six-phase flat wire wave winding structure is applicable to a 2M-layer (M=1, 2, 3 . . . ) six-phase motor whose quantity of slots of each phase in each pole is q, whose quantity of stator slots is 6q (q=1, 2, 3 . . . ) times of a quantity of poles, and whose quantity a of parallel branches is 1 or 2. Each phase of the wave winding structure has conductors in all layers of a same stator slot, and the wave windings are uniformly and symmetrically distributed. In addition, problems that a flat wire winding process is highly difficult and manufacturing costs are high due to an increase in a quantity of phases of the six-phase motor are effectively resolved.
