Abstract: A compressor includes a motor which includes a stator assembly configured to include a stator in which a hollow is formed, a plurality of coils formed by a winding wound on the stator, and an insulator for insulating the stator from the coils, and a rotor inserted into the hollow, configured to rotate about a rotation axis. The rotor includes a plurality of poles, and a curvature radius of an outer circumference of a center part of the poles is different from a curvature radius of an outer circumference of an edge part of the poles. A method for fabricating a motor includes coupling a stator hook formed in a busbar assembly having a plurality of busbars to a hook engaging part formed in the stator assembly having the plurality of coils, and fusing a winding onto a folded plate connected to the plurality of busbars.

Abstract: A motor having an improved structure in which winding patterns of a stator coil can be simplified, and a method of winding a stator coil. The motor includes a stator, a rotor and a motor shaft. The stator has a stator body and a first insulator and a second insulator that are coupled to upper and lower parts of the stator body. The rotor is disposed in the stator and configured to rotate while electromagnetically interacting with the stator. The motor shaft is coupled to the rotor so as to rotate together with the rotor, and a plurality of binding bosses are provided along a circumferential direction of one of the first insulator and the second insulator so that coils to which different voltages are applied, are wound around one of the first insulator and the second insulator.
