Drone Engines

 

The choice of drone engine will depend on many factors, especially the weight of the drone. A drone engine must be able to generate enough thrust to balance the weight of the drone and allow it to reach takeoff.


The torque of a UAV engine represents its ability to change from one speed to another. Larger propellers require higher torque motors and draw more current than lower torque motors.


While brushed motors are used in small drones, larger drones and

UAVs

will use brushless motors as they can carry the extra weight of electronics. Brushless drone motors also require

an electronic speed controller (ESC) to operate.


Electric Motors for Drones

Electric motors for drones convert electrical energy into mechanical energy in the form of linear or most commonly rotary motion. In most drone engines, this motion is the result of the attraction or repulsion of two magnetic fields. One of these fields is provided by a permanent magnet, while the other is produced by taking advantage of the fact that passing an electric current through a conductive wire creates a magnetic field around that wire.


The moving part of these two motor components that produce a magnetic field is called the rotor, and the stationary part is called the stator. The rotor will have a shaft extending from it, which allows the rotational motion of the motor and the rotational force or torque produced to be used.
