中文摘要：

基于FLUX对某型号表贴式永磁同步电机铁耗进行仿真分析研究,根据电机的传统铁耗Bertottti计算模型,得出电机不同磁密的定子铁心损耗;在考虑旋转磁场影响的条件下,首先利用有限元法改进计算模型,通过对定子铁心仿真分析,得到不同区域特征点磁场分布情况及磁密变化曲线;然后将径向和切向磁密分量叠加得到损耗,计算结果与传统模型进行对比,铁耗增加比例为19.325%,与最新研究文献的研究结果相符.

英文摘要：

Iron loss simulation analysis of a type of surface mounted permanent magnet synchronous motor （PMSM） is conducted based on FLUX, and the motor stator core loss is calculated at different flux densities. According to the conventional model Bertottti, the calculation model is improved by finite element method un- der the condition of considering the influence of the rotating magnetic field, and magnetic field distribution and the flux density curve are obtained from feature point of different regional through the simulation analysis of the stator core. Then the radial and tangential magnetic dense components are added to obtain the loss. Compared with the traditional model, the iron loss ratio is 19. 325%, which is consistent with the results of the latest re- search literature.
