The invention relates to a radial centering device for a flywheel battery. The device comprises a stator part and a flywheel. The stator part comprises an upper end stator and a lower end stator. Theupper end stator and the lower end stator are respectively provided with an annular inner magnet and an annular outer magnet. A damper is arranged in the middle of the flywheel, and the damper is a fan-shaped damper. By means of the centering device for the flywheel battery, the technical problem in the prior art that, a rotor easily deviates from the distribution center of the magnetic field during the rotation of the rotor based on an existing flywheel battery centering device, can be well solved. 种飞轮电池径向定心器，它包括定子部分以及飞轮，所述定子部分包括上端定子以及下端定子，上端定子以及下端定子中均设有环形内磁铁以及环形外磁铁，在飞轮中部设置阻尼器，阻尼器为扇环形阻尼器。本发明能解决现有飞轮电池定心器不能很好的纠正转子在转动时容易偏离磁场分布中心的技术问题。
