Claim of US Patent No. 10,461,597

1. A winding structure having a high power density, characterized in that, the winding has a multilayer 2D structure and the winding has a distributed structure with an electrical angle of 180 degrees, wherein each layer contains only one phase winding, every phase winding are arranged in an even number of layer windings, and connected with through holes at a corner of an upper portion of the coil loop, the winding structure is provided with an A-phase winding, a B-phase winding and a C-phase winding, wherein the B-phase winding and the A-phase winding have a difference of an electrical angle of 120 degrees in a tangential space, the C-phase winding and the A-phase winding have a difference of an electrical angle of 240 degrees in the tangential space, the A-phase winding, the B-phase winding and the C-phase winding form the three-phase winding symmetry in space.
