Abstract

PURPOSE:To keep an air gap between an E type core and an I type core constant while preventing the mutual displacement of the cores by welding both cores through a nonmagnetic material. CONSTITUTION:A coil 2 is inserted from the opening section 3 of the E type core 1 laminated, and the I type core 4 laminated and shaped in size slightly shorter than the width l of the opening section 3 of the E type core 1 is mounted to the opening section 3 through the nonmagnetic materials 6. The E type core 1 and the I type core 4 are integrally welded and fixed by irradiating beams such as laser beams to the nonmagnetic materials 6. The air gap between the E type core 1 and the I type core 4 is kept constant by the nonmagnetic materials 6, and displacement is not generated even when vibration, a shock, etc. are applied. Positioning and the air gap are easily adjusted when assembling, and assembling work can be facilitated.
