Many friends like to play drones, or flying cool, or taking pictures to shoot video, etc. Some friends are also interested in the internal structure of the drone, such as the power structure brushless motor, including its working principle and the meaning of KV value, so what is the brushless motor KV value of the drone? Vacuz to give you a popular science! Hope it can help you!

Brushless motor KV value of the drone.

Drone use effect is good, the speed of the main brushless motor KV value and voltage value to determine the general use of the model brushless motor, KV value has high and low, low hundreds to about three thousand, high can reach five or six thousand.

KV value means that the motor in the no-load situation, the voltage increases per 1 volt, the value of the speed increase, brushless motor this value is a constant. Motor speed = KV value X voltage, for example, KV value 1000 motor, if at 10V voltage, its speed (no-load) is 10000 rpm.

Brushless motor of the same size, brushless motor with more stator turns, KV value is lower, the output current is relatively small, but the torque is relatively large; brushless motor with fewer stator turns, KV value is high, the output current is large, but the torque is relatively small.

The smaller the KV value of the motor, the greater the power of the motor, but the lower the speed; and the larger the KV value, the smaller the power of the motor, but the faster the speed.

Drones are assembled brushless motor, no brushless motor, the drone can not fly, belongs to one of the core components, of course, brushless motor and propeller, battery, ESC have a close relationship, I hope these tips can help you!
