A motor driving device according to one embodiment of the present invention comprises: a first position detection sensor for detecting the position of a motor and self-diagnosing a defect; a second position detection sensor for detecting the position of the motor; and a control unit for receiving a position signal and a self-diagnosis signal from the first position detection sensor, and receiving a position signal from the second position detection sensor, wherein the control unit determines whether the first position detection sensor is normal according to the defect self-diagnosis signal and, if the first position detection sensor is normal, determines whether the second position detection sensor is defective by using the position signal of the first position detection sensor. Un dispositif d'entraînement de moteur selon un mode de réalisation de la présente invention comprend : un premier capteur de détection de position pour détecter la position d'un moteur et diagnostiquer automatiquement un défaut ; un second capteur de détection de position pour détecter la position du moteur ; et une unité de commande pour recevoir un signal de position et un signal de diagnostic automatique en provenance du premier capteur de détection de position, et recevoir un signal de position en provenance du second capteur de détection de position, dans lequel l'unité de commande détermine si le premier capteur de détection de position est normal en fonction du signal de diagnostic automatique de défaut et, si le premier capteur de détection de position est normal, détermine si le second capteur de détection de position est défectueux en utilisant le signal de position du premier capteur de détection de position. 본 발명의 일 실시예에 따른 모터 구동 장치는, 모터의 위치를 검출하고, 고장여부를 자가진단하는 제1 위치검출센서, 상기 모터의 위치를 검출하는 제2 위치검출센서, 및 상기 제1 위치검출센서로부터 위치 신호 및 자가진단 신호를 수신하고, 상기 제2 위치검출센서로부터 위치 신호를 수신하는 제어부를 포함하고, 상기 제어부는, 상기 고정 자가진단 신호에 따라 상기 제1 위치검출센서가 정상인지 판단하고, 상기 제1 위치검출센서가 정상인 경우, 상기 제1 위치검출센서의 위치 신호를 이용하여 상기 제2 위치검출센서의 고장여부를 판단한다.
