Title (EN) STATOR, AND MOTOR COMPRISING SAME
(FR) STATOR ET MOTEUR LE COMPRENANT
(KO) 스테이터 및 이를 포함하는 모터
Abstract:
(EN) An embodiment relates to a stator and motor, the stator comprising: a stator core having teeth; and a coil wound on the teeth, wherein each tooth comprises a body around which the coil is wound, and a shoe connected to the body, and the shoe comprises a plurality of grooves, and the width of the grooves, which are in the circumferential direction, is 90-110% of the width of a slot opening between the teeth. In addition, the motor forms grooves on the teeth of the stator, increasing the main cogging differential, thereby providing the benefit of significantly reducing the cogging torque.
(FR) Un mode de réalisation concerne un stator et un moteur, le stator comprenant : un noyau de stator ayant des dents ; et une bobine enroulée sur les dents, chaque dent comprenant un corps autour duquel la bobine est enroulée, et un sabot relié au corps, et le sabot comprend une pluralité de rainures, et la largeur des rainures, qui sont dans la direction circonférentielle, est de 90 à 110 % de la largeur d'une ouverture de fente entre les dents. De plus, le moteur forme des rainures sur les dents du stator, augmentant le différentiel de détente principal, fournissant ainsi l'avantage de réduire significativement le couple de détente.
(KO) 실시예는 복수의 투스를 갖는 스테이터 코어; 및 상기 투스에 권선되는 코일을 포함하며, 상기 투스는 상기 코일이 감기는 몸체와 상기 몸체에 연결되는 슈를 포함하고, 상기 슈는 복수의 홈을 포함하고, 원주 방향을 기준으로 하는 상기 홈의 폭은 상기 투스 사이에 형성된 슬롯 오픈의 폭의 90% 내지 110% 이내인 스테이터 및 모터에 관한 것이다. 이에, 상기 모터는 스테이터의 투스에 홈을 형성시켜, 코깅 메인 차수를 증가시킴으로써, 코깅 토크를 크게 절감하는 유리한 효과를 제공할 수 있다.
