Abstract

A prototype micro magnetic bearing actuator having an outside diameter of 2.6 mm has been fabricated at Royal Melbourne Institute of Technology and reported previously with an emphasis on fabrication issues. The discussion of this paper will focus on the design and control of the micro magnetic bearing with a particular emphasis on control system design and analysis. To this end, a simplified dynamic model for the micro actuator has been developed and used in determining controller parameters, leading to a successfully suspended non-rotating rotor in the micro magnetic bearing system.
