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： An edgewise winding method for forming an edgewise winding having a non-circular outer shape including a bent portion, a short side portion, and a long side portion is achieved by feeding a wire by a length corresponding to the short side portion or the long side portion and edgewise bending the wire by a bending jig while rotating an entire winding to form the bent portion. A side surface of the long side portion of the winding is supported by a first support block, a second support block, a first stopper block, a second stopper block, and others.
