How Servo Motors Work

I’ve noticed that distributors (Jameco, Mouser, etc) have a surprising number of introductory education articles. I’ve seen this pattern on websites for car dealerships and HVAC installers, so I assumed it was for SEO purposes. But electronic parts distribution seems like a much more niche audience; why bother with SEO?

I think it's just a tradition in the electronics world to write and publish hobby and educational articles. It dates back to well before the the Internet. People enjoy this interaction, and the distributors give them space for it.

People like HVAC installers -- I've seen most of that on YouTube, where there's a chance of monetizing the content. I've repaired nearly every appliance in my house, thanks to blogs and videos posted by strangers.
