直流电机（DC Motor）或全称直流电动机，是最常用的执行器，用于产生连续运动，并且其旋转速度可以轻松控制，使其非常适合用于需要速度控制、伺服控制或定位的应用。 通常，直流电机由两部分组成：“定子”（Stator）是静止部分，“转子”（Rotor）是旋转部分。因此，基本上有三种类型的直流电机： ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body ...
