*Kv is the motor velocity constant, measured in RPM per volt (not to be confused with kV, the abbreviation for kilovolt). The Kv rating of a brushless motor is the ratio of the motor's unloaded RPM to the peak (not RMS) voltage on the wires connected to the coils (theback-EMF). For example, an unloaded motor of Kv, 5,700 RPM/V, supplied with 11.1 V, will run at a nominal 63,270 RPM (5,700 RPM/V × 11.1 V).
