Abstract

PURPOSE:To obtain a clamping equipment of core being small, having high tensile strength and generating no local heating by a method wherein at least grooving process for prevention of eddy current is performed with an energy beam of high density. CONSTITUTION:The process of the outside shape and grooves 5 of the clamping equipment 2 of core is performed with the high energy beam of an electron beam or a lasr beam, etc., for example. By manufacturing the clamping equipment 2 of core by this way, the grooves 5 can be processed making the size of breadth thereof to extremely small, the size of the whole breadth can be made as small, nevertheless the clamping equipment 2 of core having the prescribed tensile strength can be obtained, and because the size of breadth of the parts to be divided by the grooves 5 can be made as small, eddy current loss to be generated by invading leakage flux can be reduced.
