- In order to exert the maximum capability of flywheel energy storage system( FESS), a permanent magnet biased radial magnetic bearing (PMRB) was designed for the FESS. In this paper the authors walk systematically through design and verification of the PMRB. Sections 1 and 2 introduce the working principles and mathematical models. Sections 3 and 4 details design and simulation process. In section 5, a comparison of the current stiffness and displacement stiffness are made between analysis and measurements. Finally, a brief summary and forecast was made.
