620-0085 构造：磁阻电机包括转子和定子两部分，转子是由一系列铁芯簇焊构成的，之间没有绕组也没有永磁体。定子则是由两个极对绕组构成，由交流电源供电。

　　工作原理：当电源连接到定子绕组时，流过绕组的电流会在定子中形成旋转磁场。当磁场旋转时，会在转子中引起磁阻，磁阻作用使得簇焊处的铁芯上的磁通线在簇焊处从一个铁芯簇转移到相邻铁芯簇，由于簇之间没有绕组导线来电荷流动，因此在簇之间的移动时，跨过空气间隙，这会导致空气间隙中发生局部的漩涡电流和皮效应，这些电流和效应对磁力的影响，优先影响了簇焊处，从而在簇焊处产生了磁力偏置。当磁力偏置与旋转磁场相互作用时，会在转子中产生旋转力矩，从而带动转子转动。
