Abstract
The present invention discloses a winding structure and method having a high power density, and motor applying the above. The winding of the present invention has a multilayer 2D structure, has a distributed structure with an electrical angle of 180 degrees and is manufactured in the form of a PCB, wherein each layer arranged only one phase winding. Each phase windings contains 2 layers, or 4 layers, or other even layers, of windings. The number of coil cycles in every layer is the same as the motor poles, the winding layers of a same phase are connected via a through hole, the connecting hole is arranged at a corner of an upper portion of the winding loop inside.
