Analysis of eddy currents in a plate with unequal overhangs

A theoretical analysis of edge effects is presented for the problem of a stationary plate having unequal overhangs and subjected to a traveling flux wave. The solution represents an extension of the work due to Russell and Norsworthy, wherein the overhangs were assumed to be of equal width. Since the model considered here is a general one, the results of this study should be applicable to the design and optimization of various practical devices, e.g., disk rotor eddy current brakes, vertical linear induction motors with unequal overhangs.
