Superconducting magnetic levitation flywheel energy storage device possesses advantages of the larger storage den sity and the higher efficiency of energy storage, so it has good prospects for development. This paper described the basic principle of the superconducting maglev flywheel energy storage device. The effect of the size parameters, such as the gap between the su perconductor and the permanent magnet, the radius of the superconductor and the permanent magnet and the thickness of the per manent magnet on the levitation force was researched. The simulation of the basic model of the magnetic levitation was executed by the finite element analysis software ANSYS, the magnetic tlux distribution of the model was obtained. And the relationship be tween the various parameters and the levitation force was summarized. The experiment was made to verify the obtained conclu
