METHOD OF MANUFACTURING LAMINATED CORE EXCELLENT IN ADHESION AND MAGNETIC PROPERTIES

摘要

PROBLEM TO BE SOLVED: To manufacture a laminated core which is restrained from deteriorating in magnetic properties due to distortion of steel plates and furthermore excellent in adhesive strength. SOLUTION: An insulating film mainly formed of resin is formed on the surface of a steel plate, the steel plate is formed into a prescribed shape, and the steel plates of prescribed shape are laminated and fixed together by application of pressure as they are given vibrations.
