The cutting line 4 is a fitting protrusion extending in one direction from the magnetic steel plate 1 between the cutting lines 3 and 3, and the fitting protrusion 4 is connected to the magnetic steel plate 1 at both ends. There is. 5 is the magnetic steel plate 1 after the fitting protrusion 4 is extended.
This is the fitting hole.

せることが出来る。 When the fitting protrusions 4 of the magnetic steel plates 1 are aligned and overlapped, the fitting protrusions 4 fit into the fitting holes 5 of the other magnetic steel plates 1, but the side surfaces 4a of the fitting protrusions 4 and the side surfaces of the fitting holes 5 5a means that the clearance amount of the punching tool during punching of the cutting line 3 is the press-fitting allowance, and the fitting protrusion 4 is pushed into the fitting hole 5 by pressing in the stacking direction,
The laminated steel plates 1 can be fixed to each other by tightly fitting them.

置精度が悪くなる欠点があつた。 Since the conventional lamination fixing method is configured as described above, when fitting the fitting protrusion 4 and the fitting hole 5, the fitting protrusion side surface 4a and the fitting hole side surface 5a are
Since the laminated steel plates 1 are tightly fitted with a press-fit allowance, the positional accuracy in the radial direction shown in Fig. 1 between the laminated steel plates 1 is good.
The circumferential direction is the upper slope 4b of the fitting protrusion 4 shown in FIG.
Since the lower slope 4c and the lower slope 4c are positioned in close contact with each other, the timing of positioning is slower in the circumferential direction than in the radial direction, making it difficult to correct, resulting in a disadvantage that the positioning accuracy in the radial direction deteriorates.
