Kv
From Robowiki
Motor Voltage Constant
- This number is the motor voltage constant expressed in RPM/Volt. This indicates how fast the motor will turn for a given voltage (given there is no internal resistance).
As an example, the SS5800's Kv rating is 5,800 RPM/Volt. Therefore, if a 6.0-volt battery pack is used, the SS5800's RPM would be 34,800 (6.0 x 5,800).
