cheap quadcopter 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 theweight to power storage ratio is better than any other battery. Efficiency wise, brushless motors are typically 85-90% efficient whereas a brushed DC motor is 75-80%. Windings are present on the rotor for a brushed motor as compared to in a stator for a motor. he selection of an electric FPV Drone Motor has an enormous influence on the flight characteristics of the multicopter. Tiny variations in the construction of a motor result in significant impacts regarding the weight, responsiveness and total power of the multicopter.
