So here is the thing.
I was searching the internet for information about brushless motors. Everywhere I went, they had mixed statements about it. Long threads about which is it, is it controlled by AC or DC or what have you.
I am interested in book, that is covering this subject in depth. I am focusing mainly on 3-phase brushless motors, like the ones found in old floppies. And if I'm confused if it is or isn't 3-phase, I want to learn what it actually is.
Please suggest me a book on this subject.
