英文摘要： The gyroscopic effect and magneric levitation technology are combined organically, and a flywheel battery research model is proposed，which has simple structure, high energy storage density and low cost. The related basic theory and key technology are studied emphasisly in view of the scientific problems of this new model system. The operating principle, new control method and theory are investigated. The research work mainly include: (1) The whole mathematical model of the system of the 3-dof magnetic levitation flywheel rotor is obtained through building the dynamic analysis model of the physical quantities' motion characteristics in the magnetic levitation system and the motion equations of the rotor's precession and nutation. (2) The influence of the rotor's precession and nutation on the electric machine's start and generation characteristics is explored by the study of the flywheel rotor's gyro- characteristics. Then, the influence of the flywheel is analyzed. The steady operating conditions and the start/stop transient behavior are researched. The new control method and algorithm are also investigated. (3) The influence of the parameters of flywheel rotor, the electric machine's start and generation characteristics on the levitation characteristics of the magnetic bearing are demonstrated through the resea
