A first annular form used for making a transformer core is wound from a strip of amorphous ferromagnetic material and is thereafter cut. The resulting laminations are then arranged in a second annular form with distributed gap joints, each joint involving a plurality of superposed laminations. The second annular form is then formed into a rectangular shape core and is then annealed. Then a bonding agent is applied to the transverse edges of the laminations over a region of the core removed from the joints. The joints are then separated to open the core, allowing displacement of unbonded regions of the core. Thereafter, preformed coil structure is inserted into the window of said opened core to surround a portion of the core. Then the unbonded regions of the core are returned to their original positions to remake the joints. |
