Comparison of Magnetic Field Parameters Obtained from 2D and 3D Finite Element Analysis for an Active Magnetic Bearing

Abstract:

The paper presents numerical modeling of 8-pole radial active magnetic bearing based on 2-dimensional and 3-dimensional magnetic field computation with nonlinear characteristic of magnetic material. In this work has been used numerical models based on finite element methods. In paper has been specified differences between two and three dimensional models. Results of numerical calculation have been verified by measurement of magnetic field distribution and inductances of windings.
