My first question at this forum was put at hold because initially was bad formulated and never get to normal in spite I had edited the question, so hope more luck now!
Once I am a noobie at electronics I only know to formulate the question in generics terms and because of this, I just can expect some generic help!
We have a Hubsan quadcopter/drone that has 4 brushed motors (BDC) and we want replace them with Brushless Motors (BLDC).
One of us that is more advanced at this conversion project has connected the 4 ESC (necessary for (BLDC motors) to the correspondent Mosfet. The “signal wire” of our ESC is a twisted par with white and a black wires, so the PWM Signal/White wire is connected to the Gate and the Signal/Ground to Source of Mosfet.
With these connections the BLDC are working, so the quadcopter is flying! The problem is for that happen we must keep the brushed motors connected to the Flight Controller/Receiver (integrated) and spinning at same time as BLDC! Each BDC is connected by two wires to the correspondent + and - of the FC/Receiver (see picture)!
One of us has thought that a Resistor could replace the BDC but the truth is that after applying the Ohm's Law to calculate Resistor specifications and connect it to + and – where the BDC were connected, the BLDC don´t work anymore!
The question is: if the resistor alone do not replace the BDC (or we are applying incorrectly the law) can you give us some tips to further search?
Note - brushed motors draw 1V & 0.05A at idle and 6.5V & 1A at full throttle!
