Provided are a stator, and a propeller driving device and an aircraft using the stator having an excellent heat dissipation effect by forming an insulator (or a bobbin) insulating spaces between a stator core and a coil as an insulating heat dissipation composite material having both heat dissipation performance and insulation performance. The propeller driving device includes: a radial gap type BLDC motor with an inner rotor-outer stator structure in which a rotor is placed in a circumferential shape with an air gap inside a stator; and a propeller installation bracket for mounting a propeller to a rotary shaft of the motor, wherein the stator includes: a stator core including an annular back yoke having a predetermined width so as to form a magnetic circuit and a plurality of teeth extending from the back yoke in a central direction; an insulator formed to surround an outer circumferential surface on which a coil is wound in each of the plurality of teeth; and a stator coil wound around an outer circumferential surface of the insulator in each of the plurality of teeth, wherein the insulator may be formed of an insulating heat dissipation composite material having both heat dissipation performance and insulation performance.
