Abstract :
In this paper, the principle of bearingless switched reluctance motor (BSRM) is introduced. Flux distributions and radial force of BSRM are analyzed based on finite element method (FEM). The relation curves about the radial force and the rotor position, the radial force and the current are received. It is shown that these relationships are influenced by the magnetic saturation. And the effective area of radial force is also discussed. The analyzed results are applied to derive more precise radial force model
