Brushless DC electric motor - Wikipedia, the free encyclopedia
"Kv" is the motor velocity constant, measured in RPM per Volt. 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 (the "back-EMF"). For example, a 5,700 Kv motor, supplied with 11.1 V, will run at a nominal 63,270 rpm (=5700 * 11.1).
