Propulsion Systems for Unmanned Vehicles, UAVs and Drones

Propulsion systems for UAVs (unmanned aerial vehicles) and other unmanned systems such as UGVs (unmanned ground vehicles), AUVs (autonomous underwater vehicles) and USVs (unmanned surface vehicles), typically rely on either a fuel source or an electric battery source. In the case of aerial and waterborne unmanned vehicles, this power source will turn one or more propellers or ducted fans that provide thrust for either forward movement or hovering. UGVs will be driven by traditional engines, electric systems, or a hybrid of the two.

UAV Electric Motors

Battery-powered electric propulsion systems use a motor to drive propellers, fans or wheels. They can be found in multirotor drones, fixed-wing UAVs that rely on forward flight, as well as unmanned surface, ground and underwater vehicles. Electric motors for UAVs and other unmanned vehicles may be brushed, which are simpler but noisier and more prone to wear, or brushless motors which are more efficient but often costlier.
