碩士 === 國立臺灣大學 === 機械工程學研究所 === 102 === The objective of this study is to enhance the power density of 100 kW traction motor for HEV. In this study presents a three steps rotor optimization process including magnet arrangement angle optimization, pole embrace optimization and flux barrier design. Through this process can enhance saliency ratio, reduce back emf harmonics and reduce demagnization area. In this study also compare the additional barrier between poles or magnets would influence the motor performance. Using this rotor optimization process can improve the power density of an original motor without changing too many motor design parameters. But in motor design, the winding type will influence motor’s properties a lot. This study compares the difference between FSCW motor and ISDW motor using the three steps rotor optimization process. Finally get a motor design with high power density and high performance for HEV.
