Abstract

PURPOSE:To prevent positional slippage in the process where the butting part of cores is polished, by forming a melt-stuck part in the joined part of the core and the core holder. CONSTITUTION:Core half material 7 is formed by laminating thin plates 7a consisting of materials having high magnetic permeability such as Permalloy and is fitted to recess part 8a of core holder 8 where the Cu-Zn alloy is formed into die casting, and the joined part of core half material 7 and core holder 8 is welded by microplasma to form melt-stuck parts 9a-9f. Since core 7 and core holder 8 are melt-stuck, the extent of movement of the core for the core holder is small, and dimensions of the gap depth are kept constant approximately.
