直流电机的交流电机的原理是有差异的,直流电机运转时利用永磁磁铁与通电线圈产作用生力来推动转子的,换向是为了在线圈转子转了180度之后(相当于磁场方向变化180度)再保持线圈的电流方向与现有磁场配合产生正确的力矩交流电机运转要有旋转磁场,旋转磁场依赖于方向变化的电流,而交流电正好有此特性,所以无需换向器但是,这不是的,直流电机也可以不用换向器,交流的也可以用换向器,与定转子的设计有关交流电机给自己用是为了励磁,也就是提供磁场来让线圈切割磁力线电动机和发电机没有本质区别,电动机也可以用来发电。但是发电机不能用作电动机,除非有外接电源提供磁场
交流电机自己转是因为交流电产生旋转磁场,旋转的磁场再使得转子产生感生电流,电流和线圈的磁场产生作用力。交流电机产生了电,电用在了转子上,转子会因为电流而发热。
