The serious electromechanical designer is faced with optimizing the shape of a device for a number of conflicting criteria. If the design involves eddy currents with saturable media, a true optimization will take a long time, since it requires a lot of information as input with multiple variable variations. If the analyses must be performed in three dimensions, an inordinate amount of computer time is required even for the simplest of problems. No small advantage is accrued if the problem can be approached in two dimensions. The paper outlines a technique for examining eddy currents induced in complex series wound coils for which the connections must be specified to ensure solution accuracy. A boundary element formulation is adopted in which an arbitrary constant vector potential is assigned to each conductor. The connection of the coils can be specified by placing additional constraints on these vector potentials. The technique is tested against two experiments involving forces imposed on flux eliminating coils.
