armature end

In the end, the waveform and value of electrical potential of winding and armature reaction property curve are gained through electromagnet field calculation, and compare it with the calculation result.

最后，对谐波励磁同步发电机的负载运行进行了计算，得到了基波绕组和谐波绕组的电压大小和波形以及电枢反应特性曲线。

Results show that the highest place of flux density is superposition of armature and guide sleeve end of pole piece, and the changing for pole piece inside diameter unilateral gap settle on the thrust characteristic.

通过可视化模拟和分析得知，磁通密度最高的地方是衔铁与极靴导套端重叠部分，极靴内径单侧间隙的变化对吸力起决定作用。

The result shows that armature reaction reactance can be calculated by traditional electrical machine design method; leakage reactance of semicircular slot can be determined by round-shape slot and rectangle slot leakage reactance; and FEM is more suitable for end region leakage reactance calculation.

结果表明Powerformer的电枢反应电抗可以采用传统电机设计方法计算，半圆形槽漏抗可以根据传统圆形槽和矩形槽漏抗的计算方法来确定，端部漏抗适宜采用有限元方法计算。
