Small drones are not only a hobby thing for many amateur players, but also the application of aerial model drones is getting hotter and hotter in various professional fields, such as aerial photography or agricultural tools. For now, most drones are powered by brushless motors. Why brushless motors can become the mainstream power for model airplane drones?

Droon

Kuigi eri tüüpi mootorid võivad saavutada piisava võimsuse, peavad mudellennukid lendamiseks ületama oma kaalu ja seetõttu on nende tõukejõu ja kaalu suhe suur. Kui kasutatakse tavalist mootorit, kompenseerib suurema osa võimsusest kaal, nii et isegi kui selline droon suudaks lennata, ei suudaks ta kanda muud varustust. Harjadeta mootorid suudavad pakkuda suuremat pöördemomenti ja seega toota väiksema suuruse ja väiksema kaalu juures rohkem võimsust, mis annab mudeldroonile ka lisajõudu muude seadmete, näiteks kaamerate või muude seadmete kandmiseks.

In addition, the flight and control of the model drone must be as stable as possible, and it adjusts its flight attitude through a built-in flight control chip. Sensors are used to sense various data and adjust the power of each motor in time so that stability can be maintained. However, if the motors used to generate lift produce significant vibration at any given time, it obviously puts a tremendous strain on flight control and makes it more likely to fail in the event of airflow or other instability. A brushless motor obviously has much lower vibration and its controllability is much better. Not only does it allow autonomous control of the flight controller, but it also makes flexible remote control possible. Today, there is also a competition dominated by model drones, where remote-controlled drones can quickly traverse various obstacles. Without such a hardware base, it is obviously impossible to do so.

It is due to these two performance characteristics that brushless motors have become the mainstream choice for model airplane drones. Moreover, in some light model airplane drone products, hollow cup motors are also used without iron cores, which are lighter in weight and further reduce iron losses and improve durability.
