・ is formed protruding from the residual steel plate portions 9, 9..., so the width of the strip steel plate 1 does not become wider due to the convex portions 6, 6..., and the passage through the iron core is formed through the bolt insertion hole 7. ，
7... can prevent narrowing and deterioration of motor characteristics. The convex portions 6, 6... are provided on the outer periphery of the motor cores 2, 2... at equal angles of 900°, so bolts (not shown) are inserted into the bolt insertion holes 7, 7... and tightened. The tightening strength of the motor cores 2, 2, etc. can be made uniform, and the tightening positions of the motor cores 2, 2, etc. can be freely changed in 900 increments, and when installed in a compressor, etc., it is common regardless of the shape and position of the internal parts. Motor cores 2, 2... can be used. In the above description, two rows of punching have been described, but as the number of rows increases, the material loss of the strip steel plate can be reduced when the same number of motor cores are punched as compared to one row of punching.

が多少ずれてもバリの発生も防止できる。As described above, the present invention provides a polygonal motor core made by continuously punching out a plurality of rows of strip steel plates in the longitudinal direction. , the plurality of rows of iron cores are alternately bitten into the residual steel plate portion of each row, and a convex portion in which a bolt insertion hole is drilled is formed to protrude into the residual steel plate portion, and each of the iron cores is separated. Since the sides are made straight and curved relief holes are provided connected to both ends of the separation side, the residual steel plate portion during punching of the motor iron core is reduced and material loss is reduced. Compared to parallel cutting, the width of the steel strip can be reduced, reducing the cost of materials, and since relief holes are provided on the cutting edge of each motor core, it is possible to prevent burrs from forming even if the cutting position is slightly shifted. .

Deterioration of motor characteristics can be prevented. ”
