could someone please clear up for me everything on motors from turns to performance?

*** is a turn and wrap and how do they effect the perfomace of the motor?

like i've heard that low turn motors are good for rpm (speed) but lack torque where as high turn motors lack speed but have torque.

what exactly is a turn refering to?

and i've also heard wraps, like double wrap single wrap. ex: 14t 2w, what does that mean!?
