英文摘要： To resolve problems of suspension bearing and high-speed operation in a flywheel battery, this project presents a new axial split phase permanent magnet type bearingless switched reluctance flywheel machine(BSRFM), the five degree of freedom suspension with ultra-low power loss and motor/generator operation with high speed can be realized. The research of this project is focused on the structure, parameters, modeling and operation control of this new BSRFM. The relationship between electromagnetic characteristics, system performance and machine parameters is studied, and then the design method of concerned parameters is researched. After that, A hybrid modeling strategy based on the principle modeling and numerical modeling is studied and the exact electromagnetic models under gyroscopic effect, rotor eccentricity and magnetic saturation are built. To provide a theoretical basis for the performance analysis and optimization design of this type bearingless machines. Furthermore, according to the rotor dynamic characteristics, the motion modal characteristic of flywheel rotor under high speed is analyzed and the gyroscopic effect suppression algorithm based on modal decoupling method is designed. So as to provide an effective suspension control method for the high speed bearingless flywheel rotor with good performance and strong stability. An experiment prototype and platform is designed to carry out the experimental research, the experimental results is used to verify the effectiveness of theoretical analysis and to optimize the theory model, so as to establish the basic theory and method for the new axial split phase permanent magnet type BSRFM, and lay a foundation for its practical application, especially in the field of the flywheel battery.
