Abstract

본 발명은 브러시레스 모터를 개시한다. 본 발명은 구동용 코일이 감겨지는 스테이터와, 스테이터와 공극이 유지되도록 구동용 마그네트가 부착되는 로우터로 구성되어 상호 자속작용에 의해 회전되는 브러시레스 모터에 있어서, 로우터의 한쪽면에 구동용 마그네트와 대향되도록 부착되는 제어용 마그네트와; 제어용 마그네트와 공극이 유지되도록 제어용 코일이 감겨지는 서브 스테이터와; 스테이터와 서브 스테이터를 체결에 의해 조립시키는 케이스를 포함한다. 따라서, 제어용 마그네트 및 코일의 자속작용으로 관성력의 영향을 받지 않고 로우터의 회전이 정확하게 제어되어 제품의 신뢰성 및 품질이 향상되는 것이다.The present invention discloses a brushless motor. The present invention comprises a stator in which a driving coil is wound, and a rotor to which a driving magnet is attached to maintain the stator and the air gap, wherein the brushless motor is rotated by mutual magnetic flux action. A control magnet attached so as to face each other; A sub stator in which a control coil is wound so that the control magnet and the air gap are maintained; And a case for assembling the stator and the sub stator by fastening. Therefore, the rotation of the rotor is accurately controlled without the influence of the inertia force by the magnetic flux action of the control magnet and the coil to improve the reliability and quality of the product.
