In this contribution, open circuit performances (flux linkage, EMF, cogging torque, open-circuit iron loss) of a permanent magnet radial flux rotating machine are analysed using a new hybrid analytical model and a mesh-based generated reluctance network model (MBGRN). The hybrid analytical model (HAM) is based on strong coupling of analytical solution of Maxwell’s equations with reluctance network (RN). It is shown that the hybrid analytical model allows to combine advantages of analytical and reluctance networks modeling approaches. As compared to reluctance networks modeling, the new approach helps reduce calculation time while giving fairly good results.
