Hybrid analytical modeling of a flux switching permanent magnet machines

This paper presents a new hybrid analytical modeling (HAM) approach, used for the pre-design of electrical machines. The HAM approach is based on a strong coupling of magnetic equivalent circuits (MEC) method and an analytical solution of the magnetic field method. The analytical model (AM), based on the formal solution of Maxwell's equations, is established in regions of low permeabilities thanks to the separation of variables technique. To show the capabilities offered by this new modeling approach, a flux switching permanent magnet machine is chosen as a case study. The developed model is validated by comparing performance for a machine modeled with this hybrid analytical model (HAM) and the finite element method (FEM).
