Drones are becoming more popular everyday. They are being used as toys and industrial machines. As you read, you will learn the functions of the different parts of a drone, and the physics that make a drone fly. To start with, a drone needs a powerful, yet lightweight battery. Most drones, both industrial and toy, are powered off of Lithium-Polymer batteries or LiPos. Every piece of electronic equipment in the drone needs power from the battery. This is where the power distribution board comes in. The battery connects to the power distribution board, or PDB. The board then distributes power to all of the electronic components. Many PDBs include extra pieces of tech to improve a consumer’s experience with a drone. For instance, most modern boards have BECs. A BEC, or battery elimination circuit, regulates the voltage from the battery, stepping it down to something acceptable for fragile components.

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
