![]() ![]() In this case, the 1000KV means that, for example, if we supply the motor with 2S LiPo battery which has a voltage of 7.4 volts, the motor can achieve maximum RPM of 7.4 times 1000, or that’s 7400 RPM.īrushless motors are power hungry and the most common method for powering them is using LiPo batteries. The KV rating on a brushless motor defines the RPM of the motor per volt with no load. ![]() In case you want more details how BLDC motors work, you can check the other article or watch the following video which contains explanation of the working principle of a brushless motor and how to control one using Arduino and ESC.įor this example, I have an outrunner BLDC motor with the following specifications: it has a KV rating of 1000, it can be powered using 2S, 3S or 4S LiPo battery and it requires 30A ESC. In this tutorial we will learn how to control a brushless motor using Arduino and ESC. ![]()
