Im not sure if this is the right place to post but I have a quick question.

When I was shopping for a motor I kept seeing things like 6.5T or 10.5T and never really bother with those numbers. I was mostly looking at kV speeds and saw that the ws a realative pattern. So T or Turn (if im not mistaken) has to be in some calculation to result in kV speed, or kV speed has to be in a calculation to result in Turns. I did google it but couldn't find a comprehensive explanation. Would some please explain or link me to where I can read about this.

Thank you
