Electric Flight Wiring
How to Test a Brushless Motor
In this article we are try to cover what an ESC is, terminologies relating to it, its functions and the factors to consider when buying one. Basically they are controling the speed of the motors. ESC is just like a gear box in a car, the gear box tells the wheels at which speed it must rotate, in the same way an ESC controls the speed at which the motor must rotate for the throttle applied. This throttle signal is provided by the flight controller to the ESC spinning the motor. A Brushless ESC has 3 wires coming out from it which directly plugs or gets soldered onto the 3 wires coming from the motor.
This guide will show anyone how to connect any ESC to any flight controller using common principles applicable to FPV drones. As a beginner, it can be quite confusing when it comes to connecting all of your FPV quadcopter electronics for the first time. However, as you build more drones you will notice that there are alot of common ways to connect everything, even if the electronics are different. So rather than writing another guide specific to some flight controller this guide will teach you the basic concepts to allow you to figure out how to hook just about anything FPV related. In this first part of the series, we will be talking about Motors and ESC.
