본 발명은 스테이터 코어와 코일 사이를 절연하는 인슐레이터(또는 보빈)를 방열성능 및 절연성능을 동시에 갖는 절연성 방열복합재로 형성함에 따라 방열 효과가 우수한 스테이터 및 이를 이용한 프로펠러 구동장치용 BLDC 모터에 관한 것이다. 본 발명에 따른 스테이터는 자기회로를 형성하도록 소정의 폭을 갖는 환형의 백요크와 상기 백요크로부터 복수의 티스가 중심방향으로 뻗어 있는 스테이터 코어; 상기 복수의 티스 각각에서 코일이 권선될 외주면을 감싸도록 형성되는 인슐레이터; 및 상기 복수의 티스 각각에서 인슐레이터의 외주면에 권선되는 스테이터 코일;을 포함하며, 상기 인슐레이터는 방열성능 및 절연성능을 동시에 갖는 절연성 방열복합재로 형성되는 것을 특징으로 한다.

    The present invention relates to a stator which effectively realizes heat dissipation by using an insulator (or a bobbin) that insulates a stator core from a coil and is made of an insulating and heat-dissipating composite material having both heat dissipation performance and insulating performance, a propeller drive device using the same, and an aircraft. The propeller drive device comprises: a radial gap type brushless direct current (BLDC) motor having an inner rotor-outer stator structure in which a rotor is arranged on the circumference with an air gap on the inner side of a stator; and a propeller mounting bracket for mounting a propeller to a rotating shaft of the motor, the stator comprising: a stator core comprising an annular back yoke having a predetermined width to constitute a magnetic circuit, and a plurality of teeth formed by extending from the back yoke in the center direction; an insulator surrounding the outer peripheral surface of each of the plurality of teeth around which the coil is wound; and a stator coil wound around the outer peripheral surface of an insulator on each of the plurality of teeth, the insulator being made of an insulating and heat-dissipating composite material having both heat-dissipating performance and insulating performance.
