Abstract :
Eddy current losses due to axial fluxes are computed in the stator end laminations of a salient-pole synchronous machine under open-circuit operating conditions. The calculation is carried out with the aid of a 3D finite-element package which uses a linear T-φ formulation. The domain spans a full pole pitch of the machine. The flux densities computed in the end region at points outside the stator core are compared with experimental measurements. The results and the limitations of the model are discussed
