Analytical Modeling of Synchronous Reluctance Machines with Finite Rotor Ferromagnetic Permeability

In this paper, the analytical modeling of Joukowsky-barrier SynRe machines is proposed. The rotor is modeled using the magnetic equivalent circuit (MEC), and the Fourier-based (FB) method is used to estimate the magnetic field distribution in the stator slots, slot openings, and the airgap. The developed MEC and FB models are directly coupled through the coupling boundary conditions on the rotor's outer surface. The stator iron is assumed to be infinitely permeable and the rotor iron has a finite permeability. The obtained results are validated using the finite element method.
