> Understanding the technical aspects of a servo motor and how it works

I don't feel like the article explains that at all. They explain the control signal and what the servo does as a result. The "how" in between is completely missing though. How is that pulse translated? How does the feedback work? What are the safety mechanisms involved?

I think this is a pretty good overview of how motors work and how you can write algorithms to control how much torque they generate by varying the PWM:
