Magnetic Bearings for Non-static Flywheel Energy Storage Systems (FESS)

    Abstract

    Proper dimensioning of magnetic bearings for non-static gimballed FESS is currently hindered by the lack of models that can predict the maximum forces in the bearings. If FESS is to compete with conventional electro-chemical batteries in terms of energy density, the magnetic bearings must be dimensioned optimally for weight and size. Magnetically suspended FESS has been experimentally investigated; however, the methods for theoretically predicting magnetic bearing loads are still limited. This paper presents how to determine such magnetic bearing loads in a gimballed FESS subject to a moving foundation. The predicted forces are compared with measurements from an experimental test bench with good agreement. Furthermore, the maximum forces in a gimballed FESS are compared with maximum forces in a non-gimballed FESS. It was found that the gyroscopic forces in the non-gimballed case quickly become critical making the gimbal mount essential for reducing magnetic bearing loads.
