Simultaneous Optimum Design of Rotor/Magnetic Bearing System

Abstract

In this study, a new simultaneous optimization method to design a rotor supported by an electromagnetic bearing is proposed. In this method a cross-section area of the magnet and number of coil turns, an electromagnet configuration, control gains under the capacity of amplifier and magnetic flux saturation are simultaneously designed under constraints of the maximum bearing outside diameter and bias gap. The result is checked by post design analysis and the validity was shown by using an example.
