Both work on the same principle. An ESC is made up of three key components. Now let's get a little technical. This also has a secondary function whereby if the battery that is driving the motor reaches its minimum voltage the BEC Battery Eliminator Circuit will reserve power for the flight critical controls, making sure the motor doesn't take all the power from the battery.
The processor is an integrated circuit that now days is completely contained in a single silicone semiconductor chip. Its job is to translate the information being given to it from the receiver in the model and switch the FETs to regulate the power to the motor. It "sees" the full voltage and current of the battery and motor. A FET is essentially an electronic switch that chops up the flow of electricity that in turn throttles the motor.
These simply chop up the flow of electricity to throttle the motor. So again, big thanks to Banggood. In case you want some more real live examples and learn how to control brusheless motors using Arduino you should check the part two of this tutorial. I hope you enjoyed this tutorial and learned something new. Very Good, I learned in a very easy and fun way things that seemed to be very complicated, thank you very much. So helpful! Many thanks. Even my 11 year old understood mostly. A super good article, simple and clear.

To increase the speed, the ESC simply increases the amount of time that the voltage is on while decreasing the amount of time that the voltage is off. To slow the motor down, this process is reversed. The key point in understanding brushed vs brushless ESC's is the fact that an ESC for a brushed motor doesn't care about the position of the motor. All it does is chops the voltage. Pretty straight forward.
Because brushless motors work completely differently ,controlling a brushless motor is an entirely different process. Without brushes, the ESC has no idea what position the motor is in. It needs some sort of feed back from the motor to determine exactly when to energize each pole.
The disadvantages of using sensored brushless motors. There are however, disadvantages to such motors. Sensorless brushless motor controllers can be optimised to your requirements. What is the best controller to use with a sensored brushless motor? I have a sensored brushless DC motor, can I use a sensorless brushless motor controller?
