[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly ... but we see no hard data on accuracy and repeatability which would be important for precise ...

Usually, when you want a servo motor, you simply buy one already made. But if you need something unusual, you can turn any DC motor into a custom servo you can control just like [Dejan] did.

Servo drives are a cornerstone of modern machinery, enabling precise control of motion in industrial and automated systems.
