ABSTRACT:
A method of constructing an electrical transformer having an uncut, unjointed magnetic core, which obtains the advantages of cylindrical winding of electrical conductor about the core legs, without the disadvantages of cylindrical winding associated with space factor. The new and improved method includes winding an electrical conductor about a core leg, using cylindrical winding techniques, to provide an electrical winding section having a circular cross-sectional configuration, and then re-forming the winding to a substantially rectangular cross-sectional configuration which minimizes the space occupied by the winding in the core window. This enables cylindrical winding techniques to be used to wind a conductor about another winding leg of the magnetic core. The reforming steps redistribute the winding-core space to a location outside the core window, and in a preferred embodiment of the invention, this space is filled with an auxiliary, jointed magnetic core.
