ESC

Electronic speed controllers - ESCs - are devices responsible for precisely controlling the speed of brushless motors. They receive the electrical energy from the battery (direct current) and the signal that indicates the speed that the motor should spin, and converts this to alternating current in the 3 poles that are connected directly to the motor.
