This paper concerns an investigatiôn of eddy currents and additional losses in solid parts of current fed salient pole synchronous machines. The results are obtained by the solution of the magnetic field diffusion equation. Eddy currents are determined using the finite elements method in a two dimensional machine section. The effects of working frequencies and the distributions of eddy-currents in space and in time are studied and discussed. The introduction of a distributed copper damper winding on the pole surface in the model is also discussed.Cet article est consacré aux pertes supplémentaires créées par les courants de Foucault, se développant dans les parties massives d'un pôle saillant d'une machine synchrone alimentée par des ondes ...
