Abstract
An adjustable transformer core and the method of manufacturing an adjustable transformer core, the transformer including a core and coils, the core being formed from a plurality of lamination sets, each lamination set including a number of legs and a pair of yoke members, the lamination sets being stacked in face-to-face relation so that the legs can be moved relative to each other. The coils may be wound directly on the legs and are moved toward each other to obtain predetermined characteristics. The coils are enclosed within a pair of core clamps to retain the relative position of the coils. Such adjustment can be employed to obtain different impedance or insulation levels. It is also within the contemplation of this invention to use the core as a common core for a variety of transformer designs. The method of manufacture may include the steps of providing a plurality of lamination sets with coils wound on the legs of the lamination sets, applying force to the coils to move the coils within the lamination sets and enclosing the lamination sets and coils within a set of clamps and a set of pads to maintain the position of the coils, and mounting the transformer assembly in a housing which is adjustable to the size of the core and coils.
