Abstract :
The treatment of 3D machine problems using the finite element method to model the field is examined. Methods for coupling to external circuits are reviewed and it is shown that symmetry can be taken care of by the suitable scaling of partitions of the system matrix. 3D filament wound coils and massive conductor circuits are discussed
