In the paper, an analytical method is presented for the evaluation of the air-gap flux density distribution in saturated salient pole synchronous machines with open slots, accurately taking into account the structure of the stator winding, the air-gap anisotropy and the slotting field effects. The method is based on a Park d-q decomposition of the stator m.m.f. distribution (preserving the spatial harmonics) and on the use of FEM identified saturation functions. Several FEM simulations validate the method.

Abstract
In the paper, an analytical method is presented for the evaluation of the air-gap flux density distribution in saturated salient pole synchronous machines with open slots, accurately taking into account the structure of the stator winding, the air-gap anisotropy and the slotting field effects. The method is based on a Park d-q decomposition of the stator m.m.f. distribution (preserving the spatial harmonics) and on the use of FEM identified saturation functions. Several FEM simulations validate the method.File in questo prodotto:
