There are several methods of calculation Kv.
One is dependent on the existing Kv, if you are going to rewind a motor.
New Kv = old Kv * (old # of turns / new # of turns)
Of course there is the question, if the manufacturer stated the Kv for this particular motor correctly and which brands of ESC he used for his determination.
The best method for an unknown motor is running the motor through a logger.
