kV and Turns for dummies like me

When we were running brushed motors, the only power rating I knew were the “Turns”. Turns, as the name suggests, indicates the number of copper-wire turns inside the motor. The lowest turns (T) has a motor (lower resistance), the faster the motor is (rpm).

kV work the other way around. It’s a calculated value based on RPM / Volts, or how many spins the motor does with just one Volt. The higher the value, the faster the motor.

A little table shows a comparison between Turns and kV

Turns	kV
3.5T	10,500
4.5T	9,000
5.5T	7,400
6.5T	6.400
7.5T	5,800
8.5T	5000
10.5T	4,200
13.5T	3,300
17.5T	2,200
21.5T	1,800

For example, as posted before, our Micro-T now sports a 10250kV… Well, that would read (nearly) 3.5T! Scary, isn’t it?

Hope this could be helpful, in case you’re still learning as I am.

Thanks for reading,
