MPL-B420P-SJ72AA

MPL-B420P-SJ72AA在嵌入式领域，用的大多数都是直流电机。我们拆解一些常用的来点直观的感受。 直流有刷电机，Brushed DC Motor。定子是永磁铁，转子是线圈，通电后线圈在磁场作用下转动，当转过角度后，通电的电极发生切换，转子在新的通电线圈作用力下继续转动。它的控制非常简单，通上直流电就转，通电极性互换后，转动方向也反转，转速随电压大小变化。

在下图中我们会看到一个叫碳刷的东西，它一端接在电源正负极，另一端压在换向器上。换向器随着转子转动，完成通电线圈的切换。碳刷的缺点就是会产生噪声，火花，有磨损，寿命短。所以现在的趋势是用电子换相取代这种机械换相，也就是无刷电机 BLDC(Brushless DC Motor)。
