In the finite element analysis of electrical machines the multi-conductor w
inding in a stator slot is usually modeled simply by a single conductor wit
h constant current density. The size of a finite element problem due to the
precise modeling of Eddy currents in the multi-conductor windings can be m
uch larger compared to the single conductor model Thc paper investigates a
new FEM approach for the consideration of eddy-currents in multi-conductor
windings surrounded by nonlinear media, a case typical in electrical machin
ery. The method called elimination of inner nodes, is evaluated in the pape
r as a possible solution for multi conductor eddy current problems. The pap
er presents examples and concludes in what circumstances the method of elim
ination is efficient.
