直流電機里邊固定有環狀永磁體，電流通過轉子上的線圈產生安培力，當轉子上的線圈與磁場平行時，再繼續轉受到的磁場方向將改變，因此此時轉子末端的電刷跟轉換片交替接觸，從而線圈上的電流方向也改變，產生的洛倫茲力方向不變，所以電機能保持一個方向轉動。

　　直流發電機的工作原理就是把電樞線圈中感應的交變電動勢， 靠換向器配合電刷的換向作用，使之從電刷端引出時變為直流電動勢的原理。

　　感應電動勢的方向按右手定則確定（磁感線指向手心，大拇指指向導體運動方向，其他四指的指向就是導體中感應電動勢的方向）。

導體受力的方向用左手定則確定。這一對電磁力形成了作用于電樞一個力矩，這個力矩在旋轉電機里稱為電磁轉矩，轉矩的方向是逆時針方向，企圖使電樞逆時針方向轉動。如果此電磁轉矩能夠克服電樞上的阻轉矩（例如由摩擦引起的阻轉矩以及其它負載轉矩），電樞就能按逆時針方向旋轉起來。

模數轉換器（ADC）代替了模擬系統的誤差放大器，從而將感應到的模擬電壓值轉換成二進制數。
