Abstract
A method of manufacturing a stack of interlock laminations and thereby shaping the stack of laminations into a desired shape. Each of the individual laminations is formed by a series of punching operations from sheet stock material. The laminations are blanked from the stock material, are stacked atop one another, and are interlocked in a choke. The laminations are thereafter repositioned to form the stack into a second shape. The stacking axis and the core axis may be either parallel or perpendicular to one another. The second shape of the core may be variable in that the second shape may be changed from time to time or may be continuously changed.
