为了获得制造高效旋转电机的基础数据，利用小励磁内芯对复杂结构实际定子铁芯的轴向铁损分布进行了评估。这种小励磁内芯的层压厚度约为定子铁芯厚度的1/6。因此，利用该小励磁内芯可以测量定子铁芯的周向铁损分布和定子铁芯的轴向铁损分布。然后，为了比较定子铁芯中轴向铁损耗分布的差异，我们研究了实际定子铁芯中经过层压和收缩装配两种制造工艺后的轴向铁损耗分布。在两个定子铁芯的三个地方（边缘、四分之一部分和中心）测量铁损。结果表明，实际定子铁芯的轴向铁损分布发生了明显的变化。本文报道了用小励磁内芯测量的两个实际定子铁芯在两种制造工艺下的轴向铁损分布。
To obtain the basic data to manufacture the highly effective rotating machine, the axial iron loss distribution of an actual stator core of the complex structure was evaluated by using the small excitation inner core. The laminated thickness of this small excitation inner core is approximately 1/6 of the thickness of the stator core. Therefore, the circumferential iron loss distribution of the stator core and the axial iron loss distribution of a stator core can be measured by using this small excitation inner core. Then, to compare the difference of the axial iron loss distribution in the stator core, we investigated the axial iron loss distribution in the actual stator core after two manufacturing processes, the laminating process and the shrink fitting process. The iron losses were measured in three places (the edge, the quarter part, and the center) of two stator cores. As a result of our investigation, the axial iron loss distribution in the actual stator core clearly changed. This paper reports on the axial iron loss distribution in two manufacturing processes in two actual stator cores measured by using the small excitation inner core.
