Welcome Again! In this post we will discuss about the main part of the whole Quadcopter/Multirotors system. Here we will learn about What is Brushless motor? How does a Brushless motor work?. Before knowing about What is Brushless motor? How does a Brushless motor work? you must know the basics of Quadcopters or UAV or Multirotors. As we are discussing about What is Brushless motor? How does a Brushless motor work? so we must know about the system on which we want to implement it.

What is Brushless Motor?
Whereas, Brushless electric engine which are mostly called electronically commutated engines, these are synchronous engines which are fueled by a DC electric source by means of a generator, inverter/exchanging power supply. The brushed D.C engine ought to never be utilized for operations that request long life and dependability. More you can find HERE.
How does a Motor Work?
This the working of a Brushless Motor:
The two main parts of a brushless DC Motor are Rotor and Stator. The Rotor is having a permanent magnet and the stator is having a coil arrangement. When the rotor and stator are joined then rotor is having 3 coils inside it. By applying the power one of the coil get energized and become electromagnet.
Thus in these motor there is a force of attraction between the permanent magnet and the electromagnet. As a result the opposite pole of the rotor gets attracted towards the first coil. As a result of attractive force between permanent magnet and first coil, rotor comes near to stator coil and due to this the second coil gets energized. Then the rotor comes near to the second coil. And after this when rotor is near second coil, the third coil get energized. After this process the first coil again get energized with the opposite polarity this time. And this process goes on.
Despite the fact that this engine works, it has one downside. You can see that, at any moment stand out loop is invigorated. The 2 dead coils extraordinarily decrease the force yield of the engine. Here is the secret to defeat this issue. At the point when the rotor is in this position, alongside the first coil, which pulls the rotor, you can empower the coil behind it such a route, to the point that, it will push the rotor.
The consolidated impact delivers more torque and force yield from the engine. This likewise ensures that these motor has a wonderful, consistent torque nature. Such torque nature is hard to accomplish in whatever other sort of engines.
