摘要： Disclosed are a multilayered wound coil, a stator, and a manufacturing method therefor. The stator is provided with: a stator core comprising laminated steel sheets; and a coil which is wound around a teeth section formed on the stator core and has a plurality of layers formed in the circumferential direction of the stator core. The winding of the coil proceeds in either the radial direction or the circumferential direction of the stator core, whichever direction has fewer adjacent conductors, and doubles back at the end in said direction. This reduces the difference in potential between adjacent conductors, making it possible to ensure insulation between adjacent conductors even with a thinner insulating film.

摘要： A stator includes: a stator core having a plurality of slots and teeth parts; and coils each formed by winding a flat conductor and disposed in the slots. Of the corners of the rectangular cross-section of the flat conductor, a first corner located on the inner circumference side of the coil when the flat conductor is wound to form the coil is provided with a round chamfer having a radius larger than that of another corner. When the coil is inserted into the slots of stator core elements, the rectangular cross-section of the coil is disposed such that the first corner faces toward the outer circumference side of the stator.
