The Electromagnetic Analysis of the Magnetic Bearing Using the Finite Element Method

The electro-magnetic field distribution and the effect of clearance ratio (CA) on magnetic flux leakage and the axial electro-magnetic force were analyzed and calculated by ANSYS. Through this method, we got the optimal value of clearance ratio, designed the axial magnetic bearing, and provided the theories and methods for the magnetic bearing’s analyzing and designing, which makes its designing faster and more conveniently.
