The present invention provides a motor for a drone, comprising: a rotary shaft; a stator including a hole into which the rotary shaft is inserted; and a rotor arranged on the outer side of the stator, wherein the rotor comprises: a cover part coupled to the rotary shaft so as to cover the upper portion of the stator; a body part for covering a side portion of the stator; and a magnet coupled to the inner circumferential surface of the body part, wherein the cover part comprises: a propeller coupling part including a hole through which the rotary shaft penetrates; an upper surface part connected to the body part; a connecting part for connecting the propeller coupling part and the upper surface part; and a plurality of blades arranged in the radial direction from the lateral surface of the propeller coupling part and formed so as to be spaced apart from the upper surface part. Therefore, the present invention provides the advantageous effects of preventing water or foreign material from permeating into the motor while ensuring an air passage for heat dissipation.
