Summary:Various embodiments of the present invention relate to a BLDC motor device including a plurality of sensors. The BLDC motor device may comprise: a rotor in which at least one pair of magnets is embedded and which has at least one convex portion and at least one concave portion formed at the end thereof; a stator in which at least one magnetic sensor and an optical sensor are disposed and which generates an electromagnetic force for rotating the rotor; and a processor electrically connected to the rotor and the stator, wherein the BLDC motor device is configured to identify the exact position of the rotor by using the at least one magnetic sensor to sense the positions of the magnets and using the optical sensor to sense the positions of the at least one convex portion and the at least one concave portion. Various other embodiments are possible. Divers modes de réalisation de la présente invention concernent un dispositif de moteur BLDC comprenant une pluralité de capteurs. Le dispositif de moteur BLDC peut comprendre : un rotor dans lequel est incorporée au moins une paire d'aimants et qui comporte au moins une partie convexe et au moins une partie concave formées au niveau de son extrémité; un stator dans lequel sont disposés au moins un capteur magnétique et un capteur optique et qui génère une force électromagnétique servant à entraîner en rotation le rotor; et un processeur connecté électriquement au rotor et au stator, le dispositif de moteur BLDC étant conçu pour identifier la position exacte du rotor au moyen dudit capteur magnétique pour détecter les positions des aimants et au moyen du capteur optique pour détecter les positions de ladite partie convexe et de ladite partie concave. Divers autres modes de réalisation sont possibles. 본 발명의 다양한 실시예들은, 복수의 센서를 포함하는 BLDC 모터 장치로서, 적어도 한 쌍 이상의 마그넷이 내장되고, 말단부에 적어도 하나의 볼록부 및 적어도 하나의 오목부가 형성된 로터; 적어도 하나의 자기 센서와 광 센서가 배치되고, 상기 로터를 회전시키는 전자기력을 생성하기 위한 스테이터; 및 상기 로터 및 상기 스테이터와 전기적으로 연결된 프로세서를 포함하되, 상기 적어도 하나의 자기 센서를 이용하여 상기 마그넷의 위치를 센싱하고, 상기 광 센서를 이용하여 상기 적어도 하나의 볼록부 및 상기 적어도 하나의 오목부의 위치를 센싱하여, 상기 로터의 정확한 위치를 확인하도록 구성될 수 있다. 다른 다양한 실시예가 가능하다.
