る。2. Description of the Related Art As is well known, a motor stator is operated by applying a rotating magnetic field to a rotor, but is wound around magnetic poles of the stator to enhance the original function of the stator. In order to facilitate the work of winding on the magnetic pole portion, the stator is formed by punching and caulking and laminating a yoke provided with magnetic poles at intervals in the circumferential direction, and forming the yoke on the magnetic pole of the split stator laminated core. After the winding, the divided stator laminated cores are connected to each other in a cylindrical shape, and are assembled and manufactured.

る。[0004] As another method of manufacturing a split stator laminated iron core, the yoke is not completely divided, but is partially cut out and connected at a notch residual portion, where the yoke is small to large or straight. There is a method in which a half-split stator piece that is extensible is punched, crimped and laminated, wound around a magnetic pole, then returned to a cylindrical shape to form a stator laminated core. Although the winding is facilitated by this, the thickness of the notch residual portion is somewhat increased due to expansion and contraction, and a fine gap is formed between the laminated iron core pieces, and the strength is reduced. For this reason, there arise problems such as deterioration of the interlayer density of the stator laminated iron core and deterioration of the uprightness of the cylindrical shape.
