Brushless motors 101?
Looking for an article, link or thread on brushless motors 101. I would really like to know more about the specs associated with these motors, what they mean, how they apply, etc.

"The Theory"
"A brushless motor is like a brushed motor turned inside out. This time the coils (windings) stay put and it’s the magnets that do the turning. Each winding is electronically switched in succession by power Mosfet Transistors in the controller, causing the rotor to spin. This is exactly the same way a three-phase AC motor works, the only difference is it needs a controller circuit to generate the different phases."
