Harmonic Analysis of Eddy Current Loss for Magnetic Thrust Bearings

摘要：

In MTBs, high eddy current loss will be produced in the solid stator and thrust disk. They play a significant role in limiting the high-speed operation of rotating actuators. In this paper, the flux path of a MTB was divided into six elementary parts according to the distributions of flux. A frequency model of eddy current losses for every iron part was proposed and the boundary condition was defined by a fractional transfer function. Results from FEM show its validity.
