Default Can someone explain?

Can someone please tell me what the "Kv" on the end of the brushless motor title stands for? Example, 1500Kv

Thanks,
Kevin

KV = RPM per volt

eg.
1500 kv with 7.4 Volt LiPo (2 cell) = 1500 x 7.4 = 11,100 RPM.

This is theoretical, as the motor RPM is normally a bit lower than this when spinning a Prop.

So the bigger the number the more speed, and the smaller the number the more torque.

I always thought Kv was Kilovolt!

A KiloVolt is equal to one thousand volts. It's a constant value.
