Abstract
In this paper, an analytical model of a homopolar magnetic bearing, based on a magnetic equivalent circuit (MEC), is developed. Comparison with a three-dimensional finite element (FE) model of the magnetic bearing shows that the accuracy of the developed MEC is acceptable. Therefore, the MEC can be used for the investigation of aspects such as stiffness and force linearity of the magnetic bearing, which are crucial in the design phase of a magnetic bearing. In addition, a prototype consisting of two magnetic bearings and a shaftis built for the verification of the concept applied to a rotary-linear motion system. Closed loop identifica tion performed on the experimental setup reveals the expected dynamics of the designed magnetic bearings as well as additional dynamics which are not taken into account in the design.
