Improved analytical calculation of axial AMB by means of fringing estimation
Original language description
In the engineering practice, active magnetic bearing (AMB) systems are designed to develop the force to suppress external forces acting on rotor and to support the entire rotor system. To analytically compute the force with an accuracy high enough to avoid time-consuming finite element method (FEM) optimisation, the accurate magnetic model has to be developed. According to the general theory of magnetic circuits, the model of iron is accurately modelled below the saturation limit. Lower accuracy is obtained in air-gap permanence calculation wherein linear theory, a fringing flux is usually neglected. In this paper fringing flux contribution to the air-gap permanence is studied. The fringing is modelled in FEM software for various geometry configurations focusing on the general solution without geometry dependencies. Primarily is examined the traditional shape of thrust AMB but the results can be applied on similar geometries as well as to geometries beyond the scope of axial AMB geometry. The result of the paper is a set of equations used to model fringing around air-gap.
