Everyone knows what a magnet is. But have you ever heard of an electret?
Yeah, me neither!
In fact, there’s an entire branch of science/engineering that gets very little attention these days – outside of very specific applications that like 3 people know about.
Join me for a look into the amazing world of electrostatics!
A lot of people wonder how alternating current (AC) induction motors work. In fact, I myself wondered exactly how they worked for a long time.
You see, I’m an electrical engineer, so I should know these things from my university education.
Unfortunately, in this age of digital everything, power electronics tends to get the shaft in favor of microprocessor design, digital signal processing, and so on. Digital is where the bucks are, you see…
And so, for the longest time, I never actually fully understood how AC induction motors work. DC motors are easy enough to understand, but the AC versions are a bit more complicated. That Tesla was a smart dude (the man, not the car company).
Enter a series of YouTube videos that explain AC motors so well, even a monkey with half a brain could understand it!
