The ESCs control brushless motors, one of two kinds of motors used in drones. Brushless motors have two main parts, the rotor, and the stator. The rotor contains magnets and rotates (hence the name). The stator contains electromagnetic coils connected in pairs. There are 3 sections of coils in the motor, each connected to a wire. This is where the ESC comes in to play. It takes the voltage from the PDB, combined with a signal from the flight controller and turns different sections on and off to make the motor spin in different directions. The other kind of motor is a brushed DC motor, also known as a brush motor. It uses two solid brushes to spin the motor. The brushes are charged with electricity, causing plates in the motors called commutators to spin. A big difference between brushless and brushed motors in drones, is that with the brushless motors, the outside spins, while with brushed motors, the inside
