Abstract
The present invention provides a motor for a drone, comprising: a rotary shaft; a stator including a hole in which a rotary shaft is arranged; and a rotor arranged on the outer side of the stator, wherein the rotor comprises: a cover part coupled with the rotary shaft and covering the upper part of the stator; a body part covering a side portion of the stator; and a plurality of magnets arranged on an inner circumferential surface of the body part so as to be spaced from each other, wherein the body part includes a plurality of groove portions arranged so as to be spaced from each other, thereby providing an advantageous effect of reducing the weight of a drone by reducing the weight of the rotor.
