Prototype iron loss analysis shows that as the frequency increases, the stator iron loss increases; at low speed region, time harmonic eddy-current loss accounts for the majority part of stator iron loss. Finally, the prototype manufacturing and test is going on.
对样机的铁耗分析表明:随着频率升高,定子铁耗增大;在低速时,时间谐波涡流损耗占定子铁耗的主要部分。最后,进行样机的制造与测试。
