MOTOR STRUCTURE OF UNMANNED AERIAL VEHICLE

摘要

A motor structure of an unmanned aerial vehicle includes a shaft seat, a stator and an external rotor. The stator is mounted around the shaft seat. The stator has a plurality of winding slots. The external rotor includes a shaft, a hollow body and a guiding cover. The shaft is pivotally disposed on the shaft seat. The guiding cover is disposed on one end of the hollow body, and the guiding cover has a central supporting seat, a plurality of blades and a plurality of air flow openings. The blades are connected to the central supporting seat. Each of the air flow openings is located between two adjacent blades. A number of the blades is greater than or equal to a number of the winding slots.
