Abstract

PURPOSE: To minimize an exciting current by providing bar main cores laminated with plural numbers of rectangular punched steel sheets in plural thereon and in parallel to face with each other at a given interval, and attaching subcores consisting of rectangular laminated sheets vertically to both ends of the main cores.
CONSTITUTION: A magnetic steel sheet is punched rectangularly, the steel sheet is laminated in plural to form a main core 1, and the two main cores 1, 1 are arranged oppositely in parallel to keep a given space each other. Then, rectangular steel sheets are laminated in plural to form a subcore 2, which is attached vertically to both ends of the main cores 1, 1 so that laminated faces are joined mutually. The six component parts coming in two main cores 1 and four subcores 2 are thus assembled to have mutual laminated faces joined, forming an iron core 3 nearly in "ro"(Japanese:katakana,256D) shape as a whole. A trimming die is therefore not necessary to facilitate making, and wider mutual joining suface area of cores with each other as compared with the core sectional area is utilizable, thus minimizing an exciting current.
