Abstract

PURPOSE: To obtain a uniformly laminated motor iron core by providing a raised part correcting the deviation in sheet metal gauge on each core surface.
CONSTITUTION: A blank material 1 is successively blanked with shaft holes 2 and slots 3 by pressing dies, is formed with raised parts 6 by the projection 8a of a punch 8 and the recess 9a of a die 9 and is blanked with cores 4. If these cores 4 are laminated, the deviation in the thickness on the right side 4a and left side 4b of the cores 4 is eliminated by the raised parts 6, whereby the motor iron core 5 uniformly laminated as a whole is obtained.
