Often considered a wear-and-tear part, the ball bearings in the motor provide smooth rotation and are usually made from a type of metal that can get stuck or wear down over time. Bearings exist to reduce friction of connecting pieces of material in the motor and provide a balanced rotation.
The new rules for non-hobbyist small unmanned aircraft (UAS) operations – Part 107 of the Federal Aviation Regulations – cover a broad spectrum of commercial uses for drones weighing less than 55 pounds. Pilots wishing to use their drones for commercial purposes, such as selling their photos or video, monitoring crops, or working-for-hire, must study and pass a test to receive certification of Part 107.
A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Generally, UAVs have 4 set of propellers mounted on 4 motors, but is it not uncommon to have 8 or even 16 for the high-end professional UAVs.
