Paper Abstract

In this paper we describe a design methodology which has been successfully developed for the design of magnetic bearings. Its adaptation and application to the design of a micro magnetic bearing is presented. Particular design problems of micro magnetic bearing system are addressed, such as the selection of the bearing topologies, the magnetic modeling and design of the actuators, and the modeling and performance simulation of these bearing system. The design trade-offs are considered and it is shown that the design of actuators and their control systems need to be considered concurrently. As an example, design result for a micro magnetic bearing with a diameter of 2.1 mm are presented.
