Welcome Again! In this post we will discuss about the main part of the whole Quadcopter/Multirotors system. Here we will learn about ESC catches fire & smoke| Electronic Speed Controller burns. Before knowing about ESC catches fire & smoke| Electronic Speed Controller burns you must know the basics of Quadcopters or UAV or Multirotors. As we are discussing about ESC catches fire & smoke| Electronic Speed Controller burns so we must know about the system on which we want to implement it.

ESC catches fire & smoke| Electronic Speed Controller burns

During any Research and Development i.e R&D during our work we come across many accidents which cause either harm to us or effects the equipment like burn out or fuses off. So it should be taken care off to prevent all these accidental condition to occur before hand. In our UAVs, Multirotors or Quadcopters we come across many of these situation. Most commonly among those which we too come across is Burning of ESCs i.e Electronic Speed Control. So today we will know which are the factors which results in burning of ESCs.

Before this you must know about What is ESC? How ESC Works? Electronic Speed Controller

When ESC burns out there comes out a lot of smoke, there are some factors which led ESC to burn.

Excessive P gain Value

When the value of P gain in PID algorithm is high, there will be rapid change in the speed of motors i.e. motors will draw more amount of current. Drawing more amount of current may led to burning of ESC. So ths factor  much be experimented before any harm happens to the ESCs.

Air flow

If in any case there is a harm to the ESC, it can all cover up if the air flow is good. If air flow is not good it will not help in cooling down the ESC. Therefore, mounting of the ESCs on the arms of the frame is the best location.

Quality of ESC

Wrongly rated ESC are often to catch fire. Also the small ESC in which the surface area is less will led to slow heat dissipation. Also small ESCs do not come up with the heat sink. So this is also a main reason why ESC catch fire.
