Modeling of a radial flux PM rotating machine using a new hybrid analytical model

In this paper, a new hybrid analytical modeling (HAM) approach, based on a direct coupling of analytical solution of Maxwell´s equations with reluctance networks (RN), is compared to reluctance networks modeling based on a mesh, for the study of open circuit performance of a radial field rotating machine. In order to assess the quality of results obtained from both models, both approaches are compared to finite element simulations. It is shown that the new hybrid analytical model allows to combine advantages of analytical and reluctance networks modeling. As compared to RN, the new approach helps reduce calculation time and gives good results.
