In the finite element analysis of electrical machines the multi-conductor winding in a stator slot is usually modeled simply by a single conductor with 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 much larger compared to the single conductor model. The 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 machinery. The method, called elimination of inner nodes, is evaluated in the paper as a possible solution for multi conductor eddy current problems. The paper presents examples and concludes in what circumstances the method of elimination is efficient.
