> 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?
That’s because the control circuit is hidden in a monolithic IC. If you’re really curious, here’s a datasheet for an old fashioned design with a block diagram and theory of operation described that should give you some hints. https://www.meditronik.com.pl/doc/plus/zn409.pdf
If that sort of thing interests you, there’s a whole field of control theory to study.

Interactive diagrams + code
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:

Yeah, it's more "How and Why/When to work with Servo Motors"
