Iron core structure, transformer, and magnetostriction control method

摘要

PROBLEM TO BE SOLVED: To provide an iron core structure capable of controlling the magnetostriction of an iron core.SOLUTION: The iron core structure comprises: an iron core including a leg and a yoke part; and a vertical magnetic field generating part arranged on the side surface of the leg. The leg includes the laminated structure of an electromagnetic steel sheet, and the vertical magnetic field generating part is arranged so as to generate a magnetic field in a direction vertical to the laminating direction of the electromagnetic steel sheet and the direction of a main magnetic flux passing the leg.SELECTED DRAWING: Figure 1
