The use of macro elements which replace the multiconductor winding in the t
ime-stepping finite element analysis of electrical machines is presented in
the paper. The effect of eddy-currents in the windings is considered by a
traditional finite element formulation combined with the so called eliminat
ion of inner nodes to achieve fast solution. The elimination method is inco
rporated into time stepping analysis in such a way that the creation of the
numerical macro element is performed only once in a whole time stepping an
alysis.
