| Abstract: | This paper studies the deformation and stress of a magnetic ring of an active magnetic bearing through theoretical analysis and numerical computation. The distributions of the stress caused by non symmetry magnetic force are given. The calculation results, which are obtained by using an iterative method and have taken into consideration the coupling effect of the magnetic ring's displacement and the magnetic force, conform with facts. |
