Abstract

PURPOSE: To prevent laminated cores from deterioration of electrical characteristic and eliminate any erection shaft for casting, etc. by fitting pieces in a half blanking state first and removing the half blanking portion finally.
CONSTITUTION: The first one of laminated metal is blanked, for example, for a shaft hole 3 in a laminating metal 1 and projections 5 are formed in a half blanking state for all laminated metal but the first and a core is formed by fitting each of these projections into the lower, neighboring half blanked hole 6. The core is fixed finally by casting a conductive shaft, etc. and the half blanking portion 5 is blanked. In this method fitting into the sheet metal 1 is conducted by the portion which is to be blanked finally. Therefore electrical characteristics are not hurt and an erection shaft is not required in casting process, etc. A core metal can be easily separated by blanking it every necessary number n of sheets.
