【摘要】 本文通过有限元方法对高速磁悬浮列车用长定子直线同步电机的电磁场进行了较为系统的分析。重点研究了长定子直线同步电机在改变动子极矩、定、动子电流、气隙大小的情况下,气隙磁场、悬浮力以及交直轴电感的变化情况。并通过对一系列曲线进行拟合得到了电机交直轴电感的经验公式,为电机性能的进一步深入分析奠定了基础。更多还原

【Abstract】 Abstract: The paper systematically analyzes the levitating and propulsive electromagnetic fields of the high speed magneticlevitation vehicle by the finite element method (FEM). The variation of the airgap magnetic density, the electromagnetic forceand the d-q axial inductances along with the longstator motor’s currents and the air gap length are highlighted. Then based onthe results, the series of curves are traced, which can present the relations between the performances and the dimensions of thelongstator motor clearly. All these analytical results are very important to the further analysis and the control of the longstatormotor.更多还原
