永磁直流电动机利用永磁体建立励磁磁场的直流电动机。这种电动机因没有另设的励磁系统，因而体积小,重量轻,结构简单且效率高。绝大多数微型直流电动机都是永磁的。永磁直流电动机起动和运行特性与他励、并励直流电动机基本相同。在结构上除定子部分没有励磁绕组外，其电枢、电刷、换向器等零部件均与电流励磁式直流电机相同（见电机励磁方式）。图中所示为铝镍钴永磁体励磁的磁路系统。由于铝镍钴的矫顽力较小,需要较长的永磁体有效长度(图中lm)以产生足够的磁通势,所以常采用圆筒式结构(图a)。为了避免电枢反应磁场（见电机）对永磁体的影响，在永磁电机中可加软铁极靴(图b)。在电机带负载时,这种结构可以使电枢电流产生的电枢反应磁通只通过极靴而不进入永磁体，保证了工作磁通的恒定,提高了永磁体的利用率,也有利于换向。极靴和永磁体应贴合紧密，工艺上要求较高。采用铁氧体励磁时，可采用瓦块式结构、瓦块带极靴式结构和圆筒式结构。前者适用各向异性材料，磁钢利用率高，结构简单，便于批量生产，但气隙磁通密度低。瓦块带极靴式结构可提高气隙磁通密度，但结构较复杂。圆筒式结构简单,便于生产，但材料利用率低,不利于换向。采用稀土永磁体励磁时，其磁路结构与瓦块式相似。但因它的矫顽力更大，磁极的径向尺寸可进一步缩小。
