The formula to calculate Kv for a brushed DC motor is to just divide the speed by the generated DC voltage that you measure using your multimeter. Another option for brushless motors is to buy a BL motor tester that will calculate Kv for you.Jul 29, 2015
Is Kv the same as RPM?
The higher the voltage, the faster a motor spins. The Kv rating designates the RPM a motor will spin at full throttle when unloaded given an input voltage. To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt.
What is Kv value of motor?
The Kv rating of a brushless motor is the ratio of the motor's unloaded rpm to the peak voltage on the wires connected to the coils. Knowing the Kv rating of a motor will help you determine how fast that motor will rotate when a given voltage is applied to it.

What does 1000Kv motor mean?
Suppose if you are having a motor with 1000Kv rating it means that it will produce 1000 RPM when 1 volt is supplied.
