This paper presents a newly developed adhesive coated grain oriented electromagnetic steel sheets. We developed the gapped iron-core type reactor having the new iron-core structure using this material. By adopting the adhesive coated grain oriented electromagnetic steel sheets to the leg of the reactor, the fastening studs of the laminated electromagnetic steel sheets, which are required in conventional reactor, and the through hole for the fastening studs could be omitted. This enabled us to simplify the structure and reduce the core diameter. On the other hand, we examined the magnetic flux distributions and local loss distributions in the york by the detailed magnetic field analysis to utilize the oriented electromagnetic steel sheet with bolt-less construction, and realized the reduction of dimensions and weights due to the increase of magnetic flux density. The reactor developed has such features as smaller size, lighter weight, lower vibration amplitude and lower noise level.
