How are consumer flying drones powered?
They use small DC motors. The motors have small permanent magnets made from iron and cobalt alloys. Using special alloys in the magnets makes them able to be smaller and lighter. Lithium-ion batteries are currently used to power drones as the weight to power storage ratio is better than any other battery. Motors are not just used for the propellers but are also used in the gimbal to steady cameras.
