碩士 === 國立成功大學 === 系統及船舶機電工程學系 === 104 === The goal of this thesis is to design a high speed permanent magnet generator for micro turbine power generation system. First, the property and the design process of the high speed machine are elaborated. The magnetization pattern of magnet is also considered in the design in order to improve the performance of surface permanent magnet (SPM) machine. The equivalent magnetic circuit method is developed by considering the influences of magnetization of magnets, fringing effect, magnetic flux leakage and the slot effect. From finite element simulation, the design with parallel magnetization of magnets can save the material usage of the stator up to 32%. A high rotary speed SPM generator is then designed using the analytical method developed in this thesis. The proposed design of the high speed SPM generator is verified by the Maxwell simulation and experiments on a prototype.
