ABSTRACT:
A laminated magnetic core assembly and method of manufacture having at least one notch formed along opposite sides of a strip material from which the laminations are formed. The notches on the opposite sides of the strip are punched out and separated from each other by a fixed distance. The notches minimize the amount of scrap material by avoiding the need for increasing the width of the strip from which a narrower strip having precision cut sides is formed.
