Unmanned aerial vehicles (UAVs) have played many roles in various fields in recent years, such as agriculture, industrial surveying, aerial photography, etc., and have become a hot topic in production and people’s daily lives. The motor of the UAV is one of the key components of the UAV’s dynamic system, taking an irreplaceable position in the UAV’s flying progress. UAV uses small alternating current (AC) motors to drive propellers and provide lift, helping the whole UAV system complete various actions in the air, enabling the flying device to finish tasks according to people’s expectations. Therefore, researching AC motors in the case of drone applications is greatly significant. This article explains the principle of direct current (DC) control circuits and various systems of drones at first and analyzes the advantages of applying DC control circuits to drone motors. Finally, by adjusting the parameters of the DC control circuit, the article checks the output effect of the control circuit under the background of the drone application. Experiments have shown that DC circuits with the advantages of fast feedback and minimal oscillation avoidance are suitable for the use of UAVs and can improve their maneuverability.
