The bias current in the magnetic is a fatal element in energy storage flywheel system for heat and rotational resistance. A bigger flywheel is used in the energy storage flywheel system for higher energy storage density. This lead to a strong gyroscopic effect. This paper verify a new method of design reduced-order model for mechanical system with strong gyroscopic effect which is proposed in one of our paper. The method used cholesky decomposition to construct the reduced-order model of mechanical system. In order to demonstrate the validity of this method, a 0.5 KWh class magnetic bearing system is designed based on the 10 MWh class energy storage flywheel system which used in this paper. The new zero bias magnetic bearing is used in the system. From the simulation and experiment, it had been verified that the proposed method is useful for control system design taking into account a strong gyroscopic effect.
