在有刷电机中，将各组线圈排成一个圆环形，相互之间又用绝缘材料隔开，形成一个圆柱形与电机轴连成一体，电源通过两个碳刷，在弹簧的压力下压在线圈上，每组线圈转动到碳刷下面就能给这组线圈通电。随着电机转动，给不同线圈或同一线圈不同两级通电，使线圈产生磁场两极与靠近永磁铁定子的两极有一个角度，通过同极相斥和异极相吸产生力量，推动电机转动。有刷电机与无刷电机的区别除了碳刷外，有刷电机是利用齿轮来进行控制，这就会让电机的返修率增加了；而无刷电机就不需要用齿轮，不会经常维修，使用寿命就会高一些，可靠性也比较高，不过无刷电机的控制系统成本也会相对有刷电机高；此外有刷电机的噪音比较大，而无刷电机声音小得多，工作效率也会高一些。
