ABSTRACT:
An improved magnetic core for an electrical transformer, and a method and apparatus for forming the core, are disclosed wherein the corners of core windows are configured to decrease the magnetic path length, thereby reducing the core losses and the amount of material necessary to construct the core. One exemplary embodiment includes a core window opening having an outer corner radii that are larger than the inner corner radii. Alternatively, the core window may have corners of a non-constant radii, with the outer corners having a more gradual or gentle curvature. These and other disclosed embodiments also enhance the ease of assembly of the transformer core and thus decrease or eliminate damage to the magnetic material during assembly.
