ABSTRACT:
In a laminated magnetic core wherein an adhesive is utilized to secure laminations in a unitary structure, low core compressibility is obtained by restricting the distribution of adhesive so that regions of metal-to-metal contact which surround axial compression points are kept completely free of adhesive. The core is formed by placing the laminations in assembled relation and applying a limited amount of the adhesive in a liquid state to selected core surface areas. Isolated interlaminar regions which lie intermediate of the axial compression regions are filled by the adhesive which flows therein by capillary action. The quantity of adhesive applied is carefully controlled so that capillary migration is contained wholly within the isolated bonding regions.
