Abstract:

An effort was made to produce a logical transition from the linear theory of eddy currents in solid media to the theory of Ganz Trans. AIEE 65177-183, 1946, and to show the applicability of the latter method in typical problems. The losses predicted by the new theory are somewhat higher than those predicted by Rosemberg Elektrotech. und Maschinenbau 41701-717, 1923. This result would be expected since the new theory accounts for both time harmonics of current density and phase shifts in the magnetic field. Formulas are presented which show the usefulness of the theory as a design method for inductive and conductive heating installations. See also AD14561
