摘要
采用修正软磁材料相对磁导率μr的二维有限元法来计算异步起动永磁同步电机的交直轴同步电抗.该方法综合考虑了交直轴电枢反应共磁路的问题以及永磁体励磁的饱和影响问题.通过对电抗参数的精确计算,达到对该种电机准确进行电磁设计的目的.同时亦可较为准确地进行起动设计.而缩短设计周期.本文最后通过测功机稳态实验并结合磁路计算结果,验证了该种方法的准确性.
The FEM by modifying the soft-magnetic material's relative permeability μr has been used to calculate motor's direct-and quadrature-axis synchronous reactance, which synthetically considers the interactive of the direct-and quadrature-axis flux. At the same time, it also considers the influence of the saturation of the permanent magnet. After this process, the more accurate parameters to complete the motor design are obtained. Also we can calculate the starting parameters more accurately and shorten design cycle by this method. At last, this result through experiments by using Magtrol power tester is tested.
