高速永磁电机的电频率导致明显的寄生效应，如趋肤效应、接近效应和循环电流效应。寄生效应导致电流分布不均匀，绕组的交流电阻增大。交流电阻与绕组损耗成正比，用绕组的交流电阻与直流电阻之比来表征绕组损耗。绕组的参数以及定子槽尺寸的参数都会影响寄生效应的程度。分析了一些设计参数的影响。
The electrical frequency of high speed permanent magnet motor leads to pronounced parasitic effects, such as skin, proximity and circulating current effects. The parasitic effects result in uneven distribution of currents and the increase of the ac resistance of the winding. Ac resistance is proportional to the winding loss and the ratio of ac resistance of winding to dc resistance of winding is used to characterize the winding loss. The parameters of winding, as well as the parameters of slot dimensions of stator, will affect the degree of parasitic effects. The influences of some design parameters are analyzed in this paper.
